摘要： A variable vane-type pump in which a cam ring with variable eccentricity encompasses a rotary piston comprising vanes guided in radial slots. At least one lateral surface of the rotary piston abuts on the contact surface of a control disc with pressure pocket and suction pocket. A channel is provided in the control disc whose intake opening is disposed in the direction of rotation of the pump between pressure pocket and suction pocket and in direct vicinity of the end of the pressure pocket. The channel terminates in a housing chamber, the waste oil chamber, the lubricating channels and/or into the under-vane chambers. After displacement of the cam ring, a connection can be established between the channel and the pressure pocket so that the pressure fluid still delivered can discharge via the channel to safeguard lubrication of the pump.

摘要： In an adjustable vane-type pump, there is provided an idle stroke adjusting device for variation of the pre-compression. The device comprises a laterally arranged adjustable supporting element having a substantially planar supporting surface bearing against the curved supporting surface area of the cam ring. The plane of the supporting surface of the supporting element is inclined relative to the plane which is defined by the joint axis of the delivery-limiting device and the pressure-control device as well as by the rotor axis. The curved supporting surface area of the cam ring is formed by the cylindrical peripheral surface of the cam ring. By using this extremely straightforward idle stroke adjusting device, wherein the idle stroke adjustment changes in response to the output pressure and the flow rate, respectively, a more favorable noise emission over the entire operating range of the pump is accomplished.

摘要： A hydraulic system with a hydraulic pump driven directly by an internal-combustion engine reduces the dimension, weight and number of component parts used in the state of the art systems while optimizing energy exploitation. A plurality of elements, one of which is a cam shaft adjusting device, are supplied with hydraulic pressure fluid by one and the same pump. A series of simplified hydraulic connections enables equivalent devices to be driven simultaneously by one or more pump circuits.

摘要： A suction-restricted radial piston pump is described, in particular for use with automotive vehicles. The pump delivers a flow constant over a broad speed range and involving low losses in output and generating only negligible noise. In one embodiment, a control slot (13), on the pressure side, is subdivided into several grooves (27,28) which at least in part are in communication, through check valves (32), with the pressure connection (20). An alternative embodiment provides a shape of the pressure-sided control slot in which the introducing end thereof is comparatively narrow to reduce noise at a high speed and the outlet-sided end thereof with a wider width sufficient to meet the required output. According to a third embodiment, the suction-sided slot (12) is provided with a narrow width section and a subsequent wider width section.

摘要： A hydraulic power steering system for automotive vehicles wherein the hydraulic power assistance takes place only above a predetermined steering power. A power cylinder (6) is coupled to a mechanical steering assembly, a pump (19, 36), and a control valve (12). In order to achieve safety in operation and a simple arrangement of the power steering system, a slide of a component (2) of the mechanical steering assembly is slidable with respect to the vehicle body. The slide is effected by the steering power overcoming a prestressing power, serves for the mechanical actuation of the control valve (12).

摘要： A vane-type motor is disclosed including a rotor disposed in a housing having a plurality of cam rings surrounding the rotor, which cam rings are displaceable relative to one another in the circumferential direction. Vanes associated with the cam rings subdivide a work chamber provided between the rotor and the cam rings into work cells and side plates laterally confine the work chamber. An inlet channel supplies pressure fluid to the work chamber and a discharge channel provides for discharge of the pressure fluid from the work chamber. Control channels are provided to preclude pressure impacts and noises with the cam ring displaced. The control channels terminate in the work chamber and connect the work chamber to the inlet channel. The rotor forms a control element for the control channels.

摘要： A brake power assist unit for motor vehicles, the control valve of which can be electrically actuated by means of an electromagnet which actuates a third sealing seat that allows ventilation of the operating chamber. In order to stabilize the characteristic of the load system formed by the armature of the electromagnet, a sleeve that carries the third sealing seat and the valve body of the control valve by means of constructive modifications of the control valve of the externally actuated brake power assist unit, in particular, during the pressure reduction phase, the invention proposes means that allow a controlled pneumatic pressure compensation between the operating chamber and the vacuum chamber or a reduction in the force to be generated by the electromagnet during the pressure reduction phase, i.e., during the return movement of the third sealing seat from the valve body.
