Kind Code:
A
Abstract:
PCT No. PCT/EP95/03657 Sec. 371 Date Mar. 21, 1997 Sec. 102(e) Date Mar. 21, 1997 PCT Filed Sep. 18, 1995 PCT Pub. No. WO96/09200 PCT Pub. Date Mar. 28, 1996A rotary slide valve (1) for the power steering of motor vehicles contains a rotary distributor (4) in a valve bore (5) of a valve housing (2), which distributor is connected with a valve inlet member (23). A control bushing (7) is rotatably guided over a small angle in an axial bore (6) of the rotary distributor (4). The control bushing (7) is fixedly connected to prevent relative rotation, with a valve outlet member (18). A centering device (31) is disposed between the rotary distributor (4) and the valve outlet member (18), and contains two parts which can be rotated in respect to each other, and at least one ball (37) situated between the two parts. The one part of the centering device (31) is fixedly connected with a reaction piston (32) and fixedly connected with the rotary distributor (4) against relative rotation, but is axially displaceable. The other part of the centering device (31) is fixedly connected with the valve outlet member (18) to prevent relative rotation and nondisplaceable in a predetermined position. The ball (37) is maintained in recesses (35, 36) of the two elements. In this rotary slide valve the centering device (31) can be set in respect to its centering force and its exact center position independently from the setting of the hydraulic center between the rotary distributor (4) and the control bushing (7).
