The invention relates to a valve which inside a housing (10) has a space (11) in which the valve seat (17) is arranged which is closed by a valve body (19). An actuator (15) intermittently displaces the valve seat (17). The valve body (19) is unable to follow this movement owing to its inertia and the valve seat (17) is opened slightly. The valve body (19) then impacts against a tappet (20), which together with the valve seat (17) is moved by the actuator (15). This impact displaces the valve body (19) fully away from the valve seat (17) so that the outlet opening (13) is opened completely. The flow then pushes the valve body (19) back into the closed position. The valve allows for both short response times and large valve opening. |
