Abstract

The valve includes a control piston (5) for the pressure medium path between at least one working pressure channel, and one channel connected to the pressure source and one connected to a tank. The control piston (5) is mounted to be displaceable in a housing bore, and includes sections (7,9) provided with an annular slot (12) between them. When no pressure medium is flowing, the channel (14) joined to the pressure medium source (P) is blocked by the first piston section (7), and the pressure regulation channel (15) joined to system (A) opens out into the annular slot (12), and that (16) joined to the tank (T) discharges into the annular slot (12) at piston section (9).
