<p>The invention relates to a pilot- operated feed pressure valve comprising a main stage and a pilot stage. The main stage has a piston (10) that is biased in a closed position. The piston is provided with a piston bore (22) via which an input connection (P) is linked with a rear spring compartment (24). Said piston bore (22) is associated with a throttle valve element (25) that provides a comparatively small cross-section of flow for the control oil in a pressure control function of the feed pressure valve and a comparatively large cross-section of flow in the feeding function.</p> |
