Abstract

The valve has two valve members (16,35) concentric with one another of which the pressure limiting inner valve member (35) is opened by pressure in a load chamber 13 against a spring (43) and has a sliding seal (27,36) which separates a cavity (42) in the outer valve member (16) from a load chamber (13). A throttle (45,39) provides damping of the inner valve member (35) in both directions. From pressure at load chamber 13, the outer valve 16 is subjected to an opening force and, via a spiral groove 34, to a closing force. When the direct opening force on valve 16 due to pressure at outlet 15 is greater than the net closing force due to load pressure combined with spring 32 this valve will open to allow a make up flow from outlet 15 to load chamber 13. <IMAGE>
