ABSTRACT:
A slide valve, having a pump port, a reservoir port and at least one consumer port is described, which comprises a slide 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. At least one of the consumer ports is connected to the reservoir port in the first slide position and to the pump port in the second slide position. Arranged between the adjusting assembly and the slide is a seat-controlled safety valve which, in the closed position, shuts off the adjacent open end of a longitudinal duct formed in the slide which, on the one hand, is connected to the consumer port and, on the other hand, to the reservoir port via the opened safety valve when the slide is possibly blocked and not loaded by the adjusting assembly. The longitudinal duct is closed off at the other end by an additional pressure relief valve which limits the pressure in the longitudinal duct with the safety valve usually being closed.
