<p>The combination valve (1) has a housing (2) with a through bore (3), in which axially slides a control piston (4). The valve housing contains load pressure connections (8) to a hydraulic circuit. The piston consist of a number of sections, i.e. a pressure piston (5), throttle slider (11), and a servo-piston (15). With the load pressure connections and over flows (47a,b), the through bore is divided into sections (3a-d), forming a pressure manometer (10), throttle (12), and zero circulation (18). This is such that the combination valve controls the pressure and delivery flow in the hydraulic circuit.</p> |
