Piston for electromagnetically actuate able hydraulic valve and hydraulic system with the electromagnetically actuate able hydraulic valve and a signal element

摘要

A piston for an electromagnetically actuatable hydraulic valve wherein the piston is configured cylindrical and axially movable along a central opening that extends along a longitudinal axis of a housing of the electromagnetically actuatable hydraulic valve, wherein plural connections of the housing are opened or closed according to a position of the piston wherein the plural connections are flow connected with the central opening, wherein the hydraulic valve is hydraulically actuatable by a signal element, wherein a damping system is provided for reducing oscillations of a signal pressure of the signal element that impacts the piston, and wherein the damping system is configured in the piston that includes a receiving cavity for receiving the damping system.
