Abstract: This invention relates to an air nozzle, comprising a flange intended for the attachment to a vehicle body opening, and comprising at least one air guiding element via which air flowing through the air nozzle can be deflected. Furthermore, at least two, in particular three, pivot stubs (18,20,22) are mounted to the flange (16) whose pivot axis (61) extends substantially parallel to the axis of the air flow through the air nozzle (10) before reaching the air guiding elements, and the pivot stubs (18, 20, 22) are movable in a direction parallel to their pivot axis (61).

Abstract: A venting nozzle has a housing having an air inlet through which an air flow enters the housing. The housing has an outlet through which the air flow exits. The outlet has deflection elements for deflecting the air flow. Parallel flaps are pivotably connected in the housing for shutting off the air flow. Meshing gear segments are positioned in the housing and connect the flaps. The meshing gear segments are arranged outside the air flow. A rotary control is coordinated with one of the flaps for controlling positioning of the flaps.

Abstract: An air nozzle has an air nozzle body and a lamella arrangement for directing the air flow exiting from the air nozzle. The lamella arrangement includes first lamellas connected to the air nozzle body so as to be pivotable about parallel-extending first pivot axes. A roller is fastened within the air nozzle body so as to be pivotable about a second pivot axis. The roller has second lamellas positioned slantedly to the second pivot axis. The second pivot axis and the first pivot axes extend parallel to one another.

Abstract: A heating-venting-air conditioning unit for a cabin vehicle is positioned at the roof of the cabin vehicle. The unit has at least one blower having air channels connected to a suction side and a pressure side of the blower. At least one of the air channels is connected to the suction side to form a suction channel and at least one of the air channels is connected to the blower side to form an air distributing channel. At least one of the suction channel and the air distributing channel is comprised of two half-shells manufactured by a double deep-drawing process.

Abstract: A holder for an electrical component, such as a resistor, that receives an air flow. The holder is elongated, and in the region where it receives flow has a round cross-sectional shape. The ends of the holder extend into openings in the component. The central portion of the holder has an essentially U-shape and is held in a guide that is associated with a housing.

Abstract: A narrow vent for aerating windshields of tractors, work machines, etc. The vent has a plurality of fins that spread the air stream that is directed onto a window in a fan-like manner. A portion of the fins, as side fins, are directed onto a region adjacent the vent, and the other portion of the fins, as main fins, are directed onto a region just ahead of the vent, with the angle provided by the fins corresponding approximately to a quarter circle. The air-exit plane provided by the vent extends at most insignificantly beyond the vehicle body part in which the vent is installed. All of the fins are partially recessed in the vent. The side fins are longer, and the outermost side fin is considerably longer, than the main fins.

Abstract: A fan assembly that includes an impeller driven by an electric motor. The housing for the impeller has an air intake opening and a pressure-side connection for the discharge of air, with the pressure-side connection being provided with an air inlet opening that communicates with an air conduit that in turn leads to the electric motor housing. Air that flows through the air conduit is supplied at least to the region of the commutator of the electric motor. The electric motor housing is provided with an air outlet opening for receiving air that has been supplied to the electric motor housing via the air conduit, with this air outlet opening being in flow communication with an underpressure region of the impeller remote from the pressure-side connection of the impeller housing.

Abstract: A device for heating passenger compartments. A fan and a heat exchanger are provided in a housing. To achieve a compact construction and a greater air capacity, the fan is a radial-flow fan having a rectangular air outlet opening. The heat exchanger is disposed at one of the end faces of the fan, and the air inlet side of the heat exchanger is disposed at an angle to the axis of the fan. At least one air-guiding member is provided between the delivery conduit of the fan and the inlet side of the heat exchanger. The air-guiding member changes the flow of air emerging from the opening of the fan into an approximately right-angled or rectangular flow profile having a width corresponding to the width of the heat exchanger, with the flow striking the inlet side of the heat exchanger at an acute angle.

Abstract: A heat exchanger, in the form of a radiator, for the coolant circuit of an internal combustion engine. The radiator has an upper water tank, a lower water tank that is connected to a return line, and heat exchanger tubes that extend between the upper and lower water tanks. For more uniform thermal transmission, an air-withdrawal line extends through the heat exchanger register and the lower water tank into the return line.

Abstract: An apparatus for ventilating and air-conditioning driver compartments, cabs, or the like. A base plate is provided that closes off a space formed by the roof construction and the base plate. Disposed in this space is a partition that extends at a right angle to the base plate and is disposed transverse to the direction of flow so as to divide the entire space. The partition is associated with an evaporator, and has an aperture, the dimensions of which are adapted to the air passage cross-section of the evaporator.

Abstract: A ventilating or air supply nozzle for panes, especially windshields, and at least one portion of the interior of a passenger vehicle or a driver's cab. The nozzle has an air inlet connection for fresh air and/or recirculated air, and an air outlet opening. The nozzle also includes a swivel damper which is pivotably mounted about an axis within a housing, and is provided with curved guide elements or deflectors. In order to be able to rapidly deice the windshield, the plane of the air outlet opening extends at an obtuse angle relative to the axis of the air inlet connection. The width of the free cross-sectional area of the air outlet opening is at least as great as the width of the cutting plane of the projection of the air inlet connection with the plane of the air outlet opening. A housing portion which is in the shape of a circular arc essentially covers the obtuse angle. The pivot axis of the swivel damper is disposed on that side disposed across from the housing portion.

Abstract: An arrangement of control members, especially for apparatus for heating and ventilating driver's cabs, passenger compartments, or the like in commercial vehicles. The arrangement includes a mounting plate with openings, into each of which a control member can be fixed in different angular positions. On the periphery of each opening, apertures are provided at equal angular distances apart. Each opening is associated on the display side of the mounting plate with an indicating panel, and on the rear side of the mounting plate with a fixing piece. The fixing piece and the indicating panel each have a flattened portion which enables a fixed position of the fixing piece relative to the indicating panel and relative to the control member.

Abstract: An apparatus for supplying air to a compartment. The apparatus has at least one air-inlet opening which is closable by a flap mounted to swing freely. At least one blower is provided. In order to avoid creating drafts, an electromagnet is mounted on the frame which surrounds the air-inlet opening, and the flap has an armature or member which cooperates with the electromagnet in the closed position of the flap.
