<p>A slide valve, having a pump port P, a reservoir port T and consumer ports A, B comprises a slide 46 which is spring-loaded into a first position and can be moved into a second position counter to the spring force by means of an adjusting assembly 18. At least one, A, of the consumer ports is connected to the reservoir port T in the first slide position and to the pump port P in the second slide position. Arranged between the adjusting assembly 16 and the slide 46 is a seat-controlled safety valve 26 which, in the closed position, shuts off the adjacent open end of a longitudinal duct 72 formed in the slide 46 which, on the one hand, is constantly connected to the consumer port A and, on the other hand, is connected to the reservoir port T via the opened safety valve 26 when the slide is possibly blocked and not loaded by the adjusting assembly 18. The longitudinal duct 72 is closed off at the other end by an additional pressure relief valve 26 which limits the pressure in the longitudinal duct with the safety valve 26 usually being closed. The consumer port A may be connected to a differential lock of a vehicle, while the consumer port B may be connected to a level control. <IMAGE></p> |
