Abstract
A valve (1) having an axially movable piston (2), wherein the piston (2) is arranged in a valve seat (3), the piston (2) has a peripheral groove (6) with a groove bottom (7), in which a sealing ring (12) is arranged, and a spacing between a piston axis (10) and the groove bottom (7) assumes, at least in an axial sectional plane, at least two different values in an axial region (21) around a contact point (13) between the sealing ring (12) and the groove bottom (7).
Claims19
A valve (1), comprising:
- an axially movable piston (2),
- a valve seat (3) in which the axially movable piston (2) is arranged,
- wherein the piston (2) has a peripheral groove (6) with a groove bottom (7),
- a sealing ring (12) arranged in the groove bottom (7),
- wherein at least in an axial sectional plane, a spacing between a piston axis (10) and the groove bottom (7) assumes at least two different values in an axial region (21) around a contact point (13) between the sealing ring (12) and the groove bottom (7),
- wherein the sealing ring (12) has an axial play (22) in the groove (6).
