Abstract (en)

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.

Abstract (de)

Es werden vorsteuerbare Wegeventile (10, 58, 60) vorgeschlagen, die durch ihre Bauweise die Ausbildung von ebenfalls vorsteuerbaren Ventileinheiten (50) erlauben, welche als sitzgesteuerte Impulsventile oder als Umschaltventile in außendichtender bzw. innendichtender Bauform ausführbar sind. Die Wegeventile (10, 58, 60) weisen dazu Sitzkörper (18, 20, 68, 70) mit unterschiedlich großen Ventilöffnungen auf. Ferner sind die Ventilschieber (26, 64) mit Steuerkolben (32, 34, 82, 84) unterschiedlich großer Kolbenflächen ausgestattet, die jeweils in separaten Steuerkammern (38, 40, 96, 100) geführt sind. <IMAGE>
