Abstract
A valve has a chamber (,) in a housing (,), in which the valve seat (,) is closed by a valve body (,). The valve seat (,) is supported by an actuator (,) which is capable of axially expanding and contracting. In response to an actuating signal the actuator (,) contracts which causes the valve seat (,) to move away from the valve body (,) so rapidly that the valve body (,) is not capable of following, which produces a flow passing through the valve seat (,). The flow pushes the valve body (,) back into the closed position. The valve allows short switching times and a high repetition rate to be achieved.
