    摘要: The invention relates to a controllable valve, particularly for delivering a pulsed flow of fluid. It comprises a valve body (10); a valve seat (12) dividing the inside of the body into an inlet chamber (14) and an outlet chamber (16); a valve shutter element (22) capable of moving; an actuator (24) comprising a stationary control part (26) for receiving control signals and a moving part (28); first rigid means of connection (30) for connecting the said moving part of the actuator (28) to the said shutter element (22); a mechanical stop (40′); a member (38) that can be compressed under the effect of a force applied to it, comprising a first end secured to the said mechanical stop; and second rigid means (36′) for dynamically connecting one of the faces of the said shutter element (22b) to the second end of the said compressible member (38).
