Abstract
A valve, preferably a solenoid valve, for a seat comfort system, preferably a vehicle seat comfort system, which in particular comprises at least one fluid actuator, or/and a seat, preferably a vehicle seat, which is equipped with such a comfort system, comprises a base body with a linearly movable piston. The piston is reversibly displaceable in the direction of a sealing seat and in the direction of an end stop. The piston has at least one damping element provided for mitigating its impact on the end stop or/and on the sealing seat. The piston has a channel extending through it between its two end-face regions. The damping element is arranged within this channel.

A valve, preferably a solenoid valve, for a seat comfort system, preferably a vehicle seat comfort system, which in particular comprises at least one fluid actuator, or/and a seat, preferably a vehicle seat, which is equipped with such a comfort system, the valve comprising a base body with a linearly movable piston, which is reversibly displaceable in the direction of a sealing seat and in the direction of an end stop, wherein the piston has at least one damping element provided for mitigating its impact on the end stop or/and on the sealing seat, and the piston has a channel extending through it between two end-face regions of the piston, wherein the damping element is arranged within this channel.
A valve, preferably solenoid valve, for a seat comfort system, preferably a vehicle seat comfort system, which preferably comprises at least one fluid actuator, or/and a seat, preferably a vehicle seat, which is equipped with such a comfort system, the valve comprising a base body with a linearly movable piston, which is reversibly displaceable by means of a clamping force into a closed position pressing the piston against a sealing seat and, for reaching an open position, by means of an electromagnetic drive against the clamping force in the direction of an end stop, wherein the piston has at least one damping element provided for mitigating its impact on the end stop or/and on the sealing seat, which damping element protrudes relative to an end-face region of the piston to form an annular gap spacing the piston in a closed position away from the sealing seat or/and in its open position away from the end stop, further comprising at least one compensating element designed to partially bridge the annular gap, such that, with respect to a longitudinal direction (X) of the piston, a length (a) of a portion (6a, 6b) of the damping element protruding relative to the preferably associated end-face region of the piston is less than a width (b) of the preferably associated compensating element.
