Abstract

Es wird ein Hydraulikventil (1) mit einem wenigstens zwei Anschlüsse (A, B) aufweisenden Gehäuse (2), mit wenigstens zwei im Gehäuse (2) und im Strömungsweg (4) zwischen den Anschlüssen (A, B) parallel vorgesehenen Sitzventilen (3, 3'), die je mindestens eine Steuerkante (6 bzw. 6') und wenigstens einen insbesondere kolbenartigen Ventilkörper (3 bzw. 3') umfassen, der gegenüber der Steuerkante (6 bzw. 6') im Gehäuse (2) verschiebbar gelagert ist und dessen Stirnseite (31) mit der Steuerkante (6 bzw. 6') zum Öffnen oder Unterbrechen des Strömungswegs (14 bzw. 14') im Strömungsweg (4) zwischen den Anschlüssen (A, B) zusammenwirkt, und mit mindestens einer Betätigungseinrichtung (7) gezeigt, dessen Hydraulikflüssigkeit (13) aufweisender Druckraum (10) mit mindestens einem Ventilkörper (5 bzw. 5') der Sitzventile (3, 3') zum Verschieben des Ventilkörpers (5 bzw. 5') hinsichtlich eines Öffnens oder Unterbrechens des Strömungswegs (14 bzw. 14') zusammenwirkt. Um hohe Schaltgeschwindigkeiten zu schaffen, wird vorgeschlagen, dass die voneinander getrennten Ventilkörper (5, 5') der Sitzventile (3, 3') mit einem gemeinsamen Druckraum (10) zum Öffnen oder Unterbrechen der parallelen Strömungswege (14, 14') zusammenwirken.

Figure imgaf001
There is a hydraulic valve (1) with a housing (2) having at least two ports (A, B), with at least two seat valves (3, 3) provided in parallel in the housing (2) and in the flow path (4) between the ports (A, B) , 3 ') each having at least one control edge (6 or 6') and at least one particular piston-like valve body (3 or 3 '), which relative to the control edge (6 or 6') in the housing (2) slidably mounted is and whose end face (31) with the control edge (6 or 6 ') for opening or interrupting the flow path (14 or 14') in the flow path (4) between the terminals (A, B) cooperates, and with at least one actuating device (7), the hydraulic fluid (13) having the pressure chamber (10) with at least one valve body (5 or 5 ') of the seat valves (3, 3') for displacing the valve body (5 or 5 ') with respect to an opening or interrupting the flow path (14 or 14 ') cooperates. In order to provide high switching speeds, it is proposed that the separate valve bodies (5, 5 ') of the seat valves (3, 3') cooperate with a common pressure chamber (10) for opening or interrupting the parallel flow paths (14, 14 ').
