摘要

Cut-off valve comprises a throttled flow connection extending from the closing position of a valve body (20) up to an axial distance of the valve body from the valve seat (18). The connection has a constant throttle cross-section. An independent claim is also included for a servo-valve component with the above cut-off valve. Preferred Features: The constant throttle cross-section is formed as an annular gap (38) between the valve housing (12) and the valve body.
