Abstract: A dust filter is surrounded by a frame and is held exchangeably in an air duct of a heating system or air-conditioning system of a motor vehicle and downstream of which an absorption filter may be arranged. For fitting an exchange of the absorption filter, the frame has an integrally formed edge or extension on the air-outlet side of the dust filter, which extension has latching openings into which hooks protruding resiliently from a retaining frame of an absorption filter are latched.

Abstract: An actuating device for a pivotable regulating flap in a motor vehicle rests against a stop formed on an air passage opening when closing the latter. The actuating device has an actuating member remote from the regulating flap and a connecting rod for converting the actuating stroke of the actuating member into a pivoting movement of the regulating flap. In order to obtain a self-adjusting actuating device without the necessity for readjustment operations, the connecting rod is of two-part configuration, and an elastically compressible connecting member with a prestressing force greater than the actuating force during the closing operation is secured between the two rod parts. The actuating stroke of the actuating member is sized to be larger than the control stroke of the regulating flap for its transfer into a closed position.

Abstract: The invention concerns a heating system or air conditioning system for vehicles having a heater box and an operator unit which has to be arranged separately from the heater box in the passenger compartment. In order to hold the operator unit on the heater box until the point of final assembly and for the purpose of adjusting the operator unit during preassembly, a two-part assembly aid element is provided, of which one part is firmly connected to the heater box and the other part is firmly connected to the operator unit so that the operator unit is fixed so that it cannot be varied until final assembly on the heater box. In order to configure the assembly aid element so that it can be manufactured simply and at low cost, its two parts are formed by two plug-in parts of a plug-in connection which can be pushed one into the other and a clip-type interlock is included in the plug-in connection.

Abstract: An engine bonnet integrates a water separation facility while dispensing with expensive additional parts which were hitherto necessary in order to separate concomitantly entering water from the air for a heating and air-conditioning system flowing in via an air inlet situated in the engine bonnet or between the rear edge of the engine bonnet and the windscreen. The necessary inner reinforcement of the engine bonnet panel is configured in such a way along that side of the engine bonnet which is turned towards the windscreen that it simultaneously feeds the air stream entering via an air inlet in the engine bonnet to an air-fill chamber situated upstream of the air intake duct of the heating or air-conditioning system that water separation also occurs in addition.

Abstract: In the case of a multi-part housing of a heating or air-conditioning system, there is provided, in order to prevent the passage of an unfiltered portion of air conveyed by a fan, a space receiving the leakage air produced, which space is connected to the suction side of the fan. In order to obtain a modular unit which is economical in terms of installation space, each receiving air leakage is formed by the fact that a wall area of the suction housing is attached in one piece to a bottom part of the housing. The channel thus produced is covered by an outwardly pointing flange area of the suction housing top part, which forms, on the pressure side, connected to a bar separating, on the housing side, the pressure area from the suction area of the fan, the top part of the bottom part of the housing.

Abstract: An air-conditioning system for a motor vehicle is controlled in such a manner that the temperature control in the air-conditioning mode occurs with two channels, i.e. corresponding individually to the preset desired values for the left-hand and right-hand side halves of the passenger compartment of the vehicle. This occurs in the automatic air-conditioning mode with a single channel, while the air distribution occurs in both operating modes with a single channel.

Abstract: A passenger compartment air filter arrangement for motor vehicles having a ventilation or air-conditioning system is provided with a filter for the air sucked in out of the passenger compartment of a motor vehicle. The filter is installed directly behind the cover of an intake channel. On the inlet side of the channel, the housing has a web-like flange which presses in a sealing manner into damping material of the foot space cover when the cover with the filter and a foot space cover are mounted, to achieve a good suction effect and noise damping.

Abstract: A fresh-air supply system for a vehicle ventilation device through an air inlet opening in a bonnet or hood swivellably attached to the vehicle bodywork, has a fresh-air duct which starts from the air inlet opening, the first duct portion of which is arranged underneath the air inlet opening on the bonnet and the second duct portion of which is arranged immovably on the bodywork. The two duct portions of the fresh-air duct are brought by the closing movement of the bonnet into a connection position in which a circumferential sealing flange of the first duct portion cooperates with a corresponding sealing flange of the second duct portion. The cooperating sealing flanges of the two duct portions, lying in an approximately horizontal plane, are covered over by the bonnet. The first duct portion is a water-collecting box surrounding the air inlet opening and having a drainage device.

Abstract: A device for simultaneously adjusting at least two pivoted elements, in particular valves used for air distribution in a vehicle heating or air-conditioning system, has an operating unit with a control disc which is connected to a rotary knob and a control groove which is closed upon itself and into which at least two levers engage which are pivotably accommodated by the operating unit and whose pivoting movements are transmitted to the pivoted elements. Simple tolerance compensation and installation without subsequent setting work is possible when each lever has a separate pivot bearing. The pivoting movements, occurring when the control groove is followed, of the bearing pin of each lever, with a universal-joint arrangement in between which leads away essentially in the axial direction of the bearing pins and permits length compensation, are transmitted from the operating unit to pivoted levers mounted on the heating box side.

Abstract: A filter in the inlet stream of a heating system or air-conditioning system of a motor vehicle for retaining noxious gaseous air components has the form of a tubular section which has air flowing through it transversely. The filter can be sealed at one end by a flap. For the purpose of rapidly implementable desorption with low expenditure, the filter be constructed from layered discs filled with activated carbon. The discs are separated from one another in each case by an intermediate layer consisting of material with good heat-conducting properties. The discs and the intermediate layers are clamped to each other by armatures penetrating the discs in the direction of the central longitudinal axis of the tubular section. The armatures, which have a heat-conducting connection to the intermediate layers, can be heated.

Abstract: In a filter insert which is received exchangeably in a shaft along a channel and which can be fixed sealingly relative to frame shaped shaft walls via at least one gasket preferably continuous on a flow-off side of the filter, it becomes possible to change the filter easily, without the danger of damaging the gasket, if there is at least one pressing element which can be connected to a pressure reducing device. When the pressing element is in the contracted pressure reduced position, a continuous gap forms between the gasket and associated shaft wall during a shift of the filter, this gap being cancelled when the pressure reducing device is disconnected.

Abstract: A filter arrangement in the intake airflow of a heating or air-conditioning system of a motor vehicle, comprising two filters (preferably activated carbon filters), arranged offset and at a distance on behind the other relative to the direction of air flow, through each of which a partial volume of the air to be filtered flows. An air-guiding device is arranged upstream of the filters which feeds air proportionately to the two filters to produce a uniform supply. A wall capable of preventing flow round the rear filter, is provided between the two filters.

Abstract: In heating or air conditioning equipment for the passenger compartment of a motor vehicle, the equipment being connected to the bulkhead on the passenger compartment side and covered by a dashboard provided with a glove compartment and having an air filter located on the air inlet side, it is proposed that, for easy insertion and removal of the air filter, the latter should be aligned at least approximately horizontally and located adjacent to the glove compartment insert. After the insert or a partial region of it has been removed or pivoted away, the air filter can be inserted and removed through the glove compartment opening.

Abstract: In a device for supplying fresh air to the passenger space of a vehicle, to ensure an easy filter change, at the same time with the air filter being protected against water, the fresh-air inlet is arranged in the engine hood and the water run-off is arranged on the top side, facing the fresh-air inlet, of a hood-like filter cover covering the air filter. The filter cover is fastened releasably to an air distributor box receving the air filter and carries air throughflow orifices in its casing region. With the engine hood open, the filter cover is freely accessible and can be removed from the air distributor box for the purpose of a filter change.

Abstract: In a heating/air conditioning system for a motor vehicle, with an exchangeable and selectively bypassable absorption filter which is arranged in a channel shaped housing and through which fresh air and/or circulating air can flow, a high degree of absorption is achieved when unprocessed air passing through internal leakage points at the absorption filter holder and the shut off bypass line of the absorption filter is collected and conveyed, via at least one line, to a location which is separated from the passenger space and the pressure level of which is lower than the pressure level on the flow off side of the absorption filter. Untreated air, which in certain circumstances escapes through external leakage points of a housing partition, is guided outside the passenger space, at the same time being prevented from overflowing into the latter.

Abstract: In an air-conditioning system for vehicles, with a blower, evaporator, heat exchanger and air distributor box with air-outflow ports for at least one middle nozzle and for side nozzles, the air distributor box is connected directly by means of its inlet cross-section to the evaporator. The heat exchanger is arranged aproximately centrally in the air distributor box so as to subdivide the latter into a front and a rear space portion. An air-guide connection piece extends from the front space portion which leads to the middle nozzle and which is connected to the front space portion via a cold-air scoop flap and is in communication with the rear space portion via two bypass channels, in each of which a temperature control flap is arranged. Air-outflow ports for the side nozzles are arranged in the bypass channels. Thus, in the "maximum cooling" mode, cold air passes directly from the front space portion of the air distributor box into the middle and side nozzles and improves the cooling of the passenger space.

Abstract: A coupling device for rods required to be connected together is proposed, with a connecting element having bores on both sides, into which the ends of the rods can be inserted. One bore ends in an internal ring-shaped groove coaxial to it, in which an angled end of the rod is accommodated. The other bore is constructed as a screw-threaded bore, into which the rod is engageable by a screw-threaded shoulder. In order to insert the angled end, the connecting element is provided on its housing part with a releasable cover part, which can be closed and caught afterwards. A precise length adjustment of the rods is possible by rotating the connecting element.
