Patent ID: 7857282

Claim:
A solenoid valve, with a pressure fluid Inlet channel and a pressure fluid outlet channel within a valve housing receiving a valve closure member that cooperates with a valve tappet and a magnet armature to control a pressure fluid connection between the inlet channel and the outlet channel, with the valve closure member being movable to rest on a valve seat and the magnet armature being movable to rest on a magnet core and being axially movably guided within the valve housing, with a valve spring biasing the valve member away from the valve seat, and with a magnet coil arranged at the periphery of the valve housing for the purpose of energizing the magnet armature to adopt a switch position in which the valve closure member is able to close the pressure fluid connection In the valve housing in opposition to the effect of the valve spring, wherein valve closure member ( 5 ) is arranged in a self-centering manner around a point of rotation (D) between the valve tappet ( 4 ) and the valve seat ( 14 ), wherein the valve closure member ( 5 ) has a tubular design, and the point of rotation (D) is positioned within the valve closure member ( 5 ) on the axis of rotational symmetry of its body, and wherein the valve closure member ( 5 ) includes at its outside periphery a back ring ( 17 ) which swivels about the point of rotation (D) synchronously with a self-centering tilting movement of the valve closure member ( 5 ) and seals the valve closure member ( 5 ) along its periphery in the valve housing ( 10 ).
