    摘要： The invention relates to a valve which inside a housing (10) has a chamber (11) in which the valve seat (17), which is closed by a valve body (19), is positioned. The valve seat (17) is supported by an actuator (15) capable of contracting and expanding axially. In response to an actuating signal the actuator (15) contracts in such a way that the valve seat (17) is moved away from the valve body (19) more rapidly than the valve body (19) is able to follow. This creates a flow through the valve seat (17), which flow pushes the valve body (19) back into the closed position. The valve allows for short switching times and high repetition rates.

    摘要： The invention relates to a valve comprising a closing body (25) that is located in a valve chamber (10). The valve chamber (10) is delimited at one end by an opposing wall (16) and at the other end by a piston (18). The latter (18) is pressed towards the opposing wall (16) by a pressure device (26). The closing body (25) is thus pressed against a centring seat (15), which is aligned axially with the valve seat (14). The pressure device (26) enables the valve to close securely even when a small pressure differential prevails between the valve inlet (17) and valve outlet (19).
