Abstract: A bag forming, filling and sealing machine for producing bag packages with a base or block bottom comprising a forming tube whose lower part has two segments that accomplish a transition from a circular inlet cross section to a rectangular outlet cross section via a square intermediate cross section. As a result of the intermediate cross section, differences in length longitudinally along the jacket lines from the circular inlet cross section to the rectangular outlet cross section of the forming tube are virtually equalized. As a result, bulging and corrugation of the packaging material at the side faces of the bag packages is virtually precluded.

Abstract: A fuel-injection pump of the distributor type has a distributor shaft which is coupled fixedly in terms of rotation to a drive shaft and which, during rotation, successively supplies an injection nozzle with fuel from a pump working space. Seated displaceably in each case in one of a plurality of radial bores in the distributor shaft are pump pistons which, on the one hand, limit the pump working space and, on the other hand, bear non-positively on a coaxial cam ring via rollers held in roller shoes. For a construction of the injection pump which is advantageous in manufacturing terms, the drive shaft engages over the distributor shaft by means of a cup-like coupling head, and a number corresponding to the number of radial bores, of axial slots for the displaceable reception of the roller shoes are made in the cup wall.

Abstract: The object is to reduce the weight of the hydraulic unit. The hydraulic unit (12) has a metal valve block (11) with at least one stepped receiving bore (15) for the hydraulic portion of an electromagnetically actuated valve (10). The hydraulic portion (13) is provided with a securing flange (30), which is inserted into a step (46) of the receiving bore (15) and is positionally secured by a caulking (48) formed from the metal of the valve block (11). A valve dome (16) protruding beyond the boundary plane (17) of the valve block (11) carries the electric portion (14) of the valve (10). The savings in weight is attained by using light metal, such as an aluminum alloy or the like, for the valve block (11). The hydraulic unit is intended for traction-controlled brake systems of motor vehicles.

Abstract: An engine injection system for a combined injection of fuel and an auxiliary fluid into a combustion chamber of an internal combustion engine. A fuel injection pump is used for pumping both fuel and the auxiliary fluid at high pressure. The pump communicates with an injection nozzle and, via a magnet valve assembly, with a fluid metering device, which in turn communicates via a metering line with the injection nozzle. Connecting the magnet valve assembly directly to the supply outlet of the fuel injection pump upstream of an equal-pressure valve, and providing a pressure generator in the metering device, given a suitable triggering of the magnet valve assembly, the remaining supply stroke of the pump piston of the fuel injection pump after the end of the fuel injection by the injection nozzle is utilized to generate the requisite metering pressure in the metering device to enable the auxiliary fluid that is to be metered to be stored in the injection nozzle.

Abstract: An electromagnetic valve having a magnet armature which can be moved longitudinally in a valve dome and the valve tappet of which carries a closing member of a first seat valve, which valve is open in the rest position. The first seat valve is situated in a valve chamber, from which first and second pressure-medium passages lead to first and second chambers arranged axially at both ends of the magnet armature. The connection between the first control chamber, which is remote from the closing member, and the second chamber, which is close to the closing member, is controlled by the magnet armature by a second seat valve, which is open in the rest position. When the second seat valve assumes its closed position, the pressure in the first control chamber, which is remote from the closing member, brings about a displacement of the magnet armature counter to the force of a return spring, resulting in a reduction in the cross section of flow of the first seat valve.

Abstract: The invention joins the intake module or intake tube to the engine with the aid of a displaceable retaining element. The retaining element, which in the mounted state is under initial tension, is braced against an engine retention face associated with the engine and against at least one counterpart intake module retention face joined to the intake module or intake tube. Because of the displaceability of the retaining element, the expense and effort of mounting and dismantling the intake module or intake tube to the engine by screws are substantially reduced. The engine is intended in particular for motor vehicles.

Abstract: A process for detecting the stroke motion of a body, which is displaceable in a housing, such as a valve member of an injection valve, by a measurement device disposed outside the housing, in which the stroke motion of the body is detected by means of an X-radiation penetrating the housing and detected by the measuring device.

Abstract: A method and apparatus for determining the spring force of a closing spring upon the opening of a valve, the valve is connected by means of a connection to a pressurized-gas line in which a pressure measuring device and, upstream of the latter, a variable pressure-regulating valve, a shut-off valve and a pressurized gas source are arranged. The end of the valve opposite from the pressure line connection is connected to a flow meter. After the shut-off valve has been actuated into its open position, the control pressure regulated at its outlet by the pressure-regulating valve is changed in such a way that it rises. Once the control pressure has risen to a value at which the valve closing element rises from the valve seat, i.e., the valve opens, the flow meter transmits a measurement signal which characterizes the flow of pressurized gas and which is input into a control and evaluation unit in addition to the value for the control pressure determined by the pressure measuring device.

Abstract: [The aim is to] A solenoid valve which achieves a setting of a reduced flow area which is active after a closed position of the valve is disclosed. The solenoid valve has a seat valve in a valve chamber. A magnet armature for actuating the seat valve is provided on its end face remote from the seat valve with an axially expandable hollow part whose interior, acting as a control chamber, is connected to a valve sub chamber through a pressure fluid channel. A [D]dynamic pressure is generated in the partly open position of the seat valve in the valve subchamber and is capable through expansion of the hollow part in the control chamber of causing a force which acts on the magnet armature against the force of a resetting spring and on the basis of which the seat valve maintains its partly open position. The valve can be used in slip-controlled hydraulic brake systems of motor vehicles.

Abstract: A clean air facility is proposed in which a clean air room is formed by welding the sides, ceiling, ducts and flooring together to avoid any friction movement between the wall and ceiling of the clean air room. A filter-blower is supported on a frame support outside of the room so that it is easier to service the filter-blower and it is easier to move the facility since the filter-blower can be detached and separately moved. The air from the filter-blower is directed directly into elongate cells in the ceiling from which the air is distributed via apertures in the ceiling evenly throughout the clean air room.

Abstract: An electromagnetic valve having a magnet armature which can be moved longitudinally in a valve dome includes a valve tappet which carries a closing member of a first seat valve, which is open in the rest position. The first seat valve is situated in a valve chamber, from which first and second pressure-medium passages lead to ends of the magnet armature, which is sealed off at the circumference. The connection between the first pressure-medium passage and a control chamber between that end of the magnet armature which is remote from the closing member and the valve dome is controlled by a second seat valve (54), which is closed in the rest position. When the second seat valve (54) assumes its open position, the pressure in the control chamber (46), which is remote from the closing member, brings about a displacement of the magnet armature counter to the force of a return spring, resulting in a reduction in the cross section of flow of the first seat valve.
