Abstract (en)
[origin: EP1035331A2] A control chamber(38,40) is provided for each control piston(32,34), and the seating components(18,20) have differently sized valve ports(22,24). To create an externally sealing system whereby the end faces of the seating component facing away from each other interact with the spool(26), the seating component which controls a pressure medium connection between the pressure medium channels(P,A) has the larger valve port and lies adjacent to the control piston(32) with the smaller piston area.
