Abstract: A vane pump has a pump flange, a cam ring, a pressure plate and at least one pin extending axially through the pump flange, the cam ring and the pressure plate, the pin being preloaded in an axial direction thereof by means of at least one spring element.

Abstract: A vane cell pump comprises a contour ring having an inner peripheral face and a rotatable rotor which has a plurality of conveying elements displaceable radially relative to a rotation axis. The inner peripheral face includes a plurality of pump portions each constructed with an intake region and a pressure region which are passed through by the conveying elements during rotation of the rotor. A narrow location at which the conveying elements are displaced radially inward toward the rotation axis to a greatest extent, is located between a pressure region and a subsequent intake region. By applying a part-stroke, an auxiliary start contour which is arranged between the rotation axis and the inner peripheral face radially inside the conveying elements in the region of at least one pump portion displaces the conveying elements to the greatest extent radially inwardly.

Abstract: There are described a vane cell pump and a method for operating a vane cell pump. The vane cell pump comprises a hollow-cylindrical contour ring which is arranged between two side plates and which has an inner peripheral face and a rotor which is rotatably supported about a rotation axis which extends parallel with the cylinder axis of the contour ring and which has a plurality of conveying elements which can be displaced radially relative to the rotation axis and which are urged against the inner peripheral face during a rotation of the rotor. The inner peripheral face is formed in such a manner that a number corresponding to the number of flows of the vane cell pump in respect of pump portions are each constructed with an intake region and a pressure region which are passed through by the conveying elements during a rotation of the rotor.

Abstract: A pump, particularly a vane-type pump, including a rotor guiding at least one vane and resting against at least one pressure plate, which has at least one pressure through-hole and at least one under-vane through-hole, the holes being connected to a pressure outlet provided in a housing of the pump or in a transmission housing. In between the pressure plate and the housing a flow guide device is arranged, which delimits a fluid path from the pressure through-hole past the under-vane through-hole to the pressure outlet.

Abstract: A ventilation device (10) for a motor vehicle includes a housing (12) made of plastics and at least one ventilation flap (14) molded to the housing (12). The housing (12) has an opening (24) in the connecting region of each ventilation flap (14). A mold for producing the ventilation device (10) includes two cores (26, 28), which in an injection position define the contour of a ventilation flap (14) and in a demolding position provide for demolding the molded part formed in the mold. In the injection position, an opening (32) is formed between the two cores (26, 28) in the connecting region of the ventilation flap (14). In a method for producing the ventilation device (10) by means of the mold, the ventilation flap (14) is molded to the housing (12) through the opening (24) in the housing (12).

Abstract: A vent flap, in particular for venting an interior of a vehicle, includes a frame (12) consisting of a first material and at least one non-return flap (18). The frame (12) has a continuously surrounding spring member (20) which is formed on the frame (12) and includes, at least in partial regions, a seal (24) made of a second material.

Abstract: An air vent is provided that is capable of delivering a distributed divergent air flow with a predominant direction of flow that can be changed within a wide range of mutually perpendicular directions. In one embodiment, the air vent has an outlet grid that is generally ball shaped and that is rotatably mounted at an end of an air duct for rotation about its center. Each of the multiple outlet openings of the grid points to a direction that is different from pointing directions of all other outlet openings so that a divergent air flow is obtained. By rotating the ball shaped grid about its center, the predominant direction of air flow can nevertheless be changed in a within a wide range.

Abstract: A non-return valve (10) for ventilating a vehicle interior, having a frame (12), in which at least one outflow opening (14) is configured. The outflow opening (14) is surrounded by a valve seat (16) and at least one valve flap (18). The valve flap (18) can move between a closed position, in which the valve flap (18) contacts the valve seat (16) and closes the outflow opening (14), and the opened position in which the valve flap (18) releases the outflow opening (14). The valve flap (18) is made of an elastically springy material and is attached such that a return force is generated which urges the valve flap (18) toward the valve seat (16).

Abstract: An apparatus (100) controls the temperature of air flow from a temperature control system (10) The apparatus (100) includes a blend door (150), an output gear (140), and a biasing mechanism (124) The biasing mechanism (124) facilitates rotation of the output gear (140) in a first rotation direction (136) and impedes rotation of the output gear (140) in a second rotation direction (138) opposite the first rotation direction (136) This results in the torque necessary to rotate the output gear (140) in the first rotation direction (136) being substantially equal to the torque necessary to rotate the output gear (140) in the second rotation direction (138).

The apparatus (100) includes a blend door (150), an output gear (140), and a biasing mechanism (124). The blend door (150) blocks air flow and has a plurality of positions, each blocking different amounts of air flow. The blend door (150) is rotatable about a first axis (142) between each of the plurality of positions. The output gear (140) is secured to the blend door (150) and is rotatable about the first axis (142) to rotate the blend door (150) between each of the plurality of positions.
