A valve arrangement in a hydraulic circuit comprises a longitudinal duct 3
and a transverse duct 2. A throttle slide 10 can be displaced in the
direction of the longitudinal duct 3. Arranged in the throttle slide 10
is a valve piston 25, by means of which the flow through the hollow
throttle slide 10 can be enabled or blocked. The flow of hydraulic fluid
takes place through two groups of passage holes 33a, 35a, which are
arranged in the throttle slide 10. The interaction of pressure and flow
direction of the hydraulic fluid, and also the restoring force of a slide
spring 20 and a piston spring 30, achieves a situation where hydraulic
fluid can flow through the valve arrangement in both directions but that
a throttling action occurs only when the hydraulic fluid flows from the
transfer duct 2 to the longitudinal duct 3 under increased pressure.
