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

An electromagnetically actuatable hydraulic valve, comprising:

• a piston arranged in a housing;
• and
• a damping system including a first hollow damping element that is axially movable in the piston and a spring element that is axially supported at the piston and at the first hollow damping element,
• wherein the piston is configured cylindrical and axially movable along a central opening that extends along a longitudinal axis of the 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 piston is axially movable by a force generated directly at the piston by a hydraulic signal pressure from a signal element,
• wherein the damping system reduces oscillations of the force generated directly at the piston by the hydraulic signal pressure from the signal element when the piston is at the position,
• wherein an entirety of the damping system including an entirety of the first hollow damping element and an entirety of the spring element is received in a receiving cavity configured in the piston,
• wherein the entirety of the damping system always moves together with the piston when the piston moves,
• wherein the first hollow damping element seals against the signal pressure along an axial travel range of the first hollow damping element in the piston, and
• wherein the first hollow damping element partially envelops the spring element.
