Abstract
A pressure responsive valve for distributing the fluid under pressure delivered by a fluid pressure source to two user components, one of which is connected to an accumulator. The device includes a control valve which is disposed in a line connecting the fluid pressure source with a first user component and governs the cross-section of the passage in that line. The control valve has a control chamber and cross-section reducing member when the control chamber is in communication with the fluid pressure source. When the control chamber communicates with the return line the cross-sectional area of the passage increases. In addition a pilot and/or stop valve is included which changes its position depending upon the pressure existing in the line connecting the fluid pressure source with the second user component. The pilot/stop valve provides for communication between the control chamber and the fluid pressure source below a predetermined switching pressure at the second user component and connects the control chamber with the return line when the switching pressure is exceeded and interrupts the connection from the source to the second user component until the pressure at the second user component drops below the switching pressure.
