- Fig. 4 and 5 shows the position of the sections A-A, B-B, C-C in the valve block 1, wherein the longitudinal sections A-A and B-B are guided through the longitudinal axis of the valve assembly and the cross-section in the amount of a fail-safe means 18 described below is performed.
- a continuous longitudinal bore 3 is formed, in which a rotary valve 2 is arranged rotatably about its longitudinal axis.
- the rotary valve 2 is rotatable by means of a schematically illustrated electric stepping motor 26.
- the rotary valve 2 has a cylindrical body, which is supported at its axial end regions via two ball bearings 4, 5 radially to the valve block 1.
- the longitudinal bore 3, which receives the rotary valve 2 is sealed at one of its two axial ends by a screw plug 6 with a sealing ring 7 to the outside and secured. At the other end of the rotary valve 2 is flush with the longitudinal bore 3 from.
- the rotary valve 2 has two axially spaced radial bores 8, 9.
- the remote from the screw 6 radial bore 8 is formed as an input valve, via which in the axial plane of the input in the valve block 1 formed, transversely oriented supply channel 10 for a pressure medium, such as a hydraulic brake fluid, with a brake pressure channel 1 1 is connectable.
- the radial bore close to the closure screw 6 tion 9 is formed as an output valve, via which a trained in the axial plane of the output in the valve block 1 transversely oriented return passage 16 with the brake pressure channel 1 1 is connectable.
- the brake pressure channel 1 1 consists of a first transverse channel 12, a second transverse channel 17 and a longitudinal channel 13, which are also formed in the valve block 1.
- the first transverse channel 12 extends in an open position of the input valve whose radial bore 8, crosses the longitudinal channel 13, and is closed to the outside pressure-tight by a closure element 14a.
- the second transverse channel 17 extends in an open position of the output valve whose radial bore 9, crosses the longitudinal channel 13, and is sealed to the outside pressure-tight by a closure element 14c.

This results in two switching positions of the rotary valve. 2
- the lubrication of the two ball bearings 4, 5 is advantageously carried out by means of leakage oil, which is formed by the used in the valve assembly or in the valve block 1 hydraulic oil for actuating the brake system.
- the leakage oil accumulates, inter alia, in the region of the two axial ends of the rotary valve 2 and passes within the valve block 1 through the two ball bearings 4, 5 via a first connecting channel 27 and a second connecting channel 28 in a manifold 25, which via an unrecognizable connection line with the said return channel 16 is connected (Fig. 1, Fig. 2).
- the arranged in comparison with the manifold 25 in another plane of the valve block 1 return passage 16 leads the leakage oil back into a collecting container, not shown for the hydraulic oil. Accordingly, no separate supply of the two ball bearings 4, 5 takes place with a special lubricating oil, since the hydraulic oil used here has sufficiently good lubricating properties for the ball bearings 4, 5 as the pressure medium of the brake system. However, this concept should not use classic brake fluid.

- the check valve 18 consists of a valve ball 21 which is seated on a valve seat 23, wherein the valve ball 21 is pressed against the valve seat 23 by a helical compression spring 22, which is supported on the closure element 14 f inside.
- a first branch channel 19 leads perpendicular to the supply channel 10 in front of the input valve 8 and a second branch channel 20 at the intersection of the first transverse channel 12 with the longitudinal channel 13 after the input valve 8.
- the two branch channels 19, 20 are outwardly through in each case a closure element 14d, 14e sealed pressure-tight.
- the first branch channel 19 is operatively connected to the spring-loaded, ie the biased side with the check valve 18.
- the second branch passage 20 is operatively connected to the check valve 18 on the side of the brake pressure channel 1 1, that is, the actuating side.
- the check valve 18 thus bridges the input valve. 8
- the operation of the fail-safe device 18 is as follows:
- the check valve 18 is closed. If an overpressure with respect to the inlet occurs on the brake cylinder side, in particular in the case of a blocked or blocked inlet valve 8, the valve ball 21 lifts off from its valve seat 23 as soon as the spring force of the screw pressure spring 22 is overcome by the hydraulic pressure and releases the path in the direction of the supply channel 10 of the pressure medium.
