<p>The valve has a housing with displaceable hollow piston, divided by a throttle into two pressure chambers, each having radial passage bores in the walls. One open piston front end is connected to a pressure medium supply, which charges the piston via the throttle in an axial direction. On the other side, the piston is charged by a spring in the opposite direction and is pressed against a stop. The second pressure chamber is connected with a relief valve, independent of the axial position of the piston in the valve housing. The relief valve is positioned between the second chamber and a relief outlet.</p> |
