<p>The valve (1) has a valve body (9) including a pressurized region within a contact surface between the valve body and a valve seat surface (7) in a direction of the valve seat surface. The pressurized region is operative in a lift direction of the valve body. A resultant force from spring force of valve spring (11) and actuating force of an actuator (23) acts on the valve body. An additional region of the valve body is pressurized with a damping medium, when the damping medium flows into the valve body over a through hole (25) in a closing direction of the valve body.</p> |
