Controllable valve particularly for delivering a pulsed flow of fluid

Controllable valve particularly for delivering a pulsed flow of fluid, comprising:

• a valve body;
• a valve seat dividing the inside of the valve body into a fluid inlet chamber and an outlet chamber;
• a valve shutter element capable of moving in one direction of travel to collaborate with the valve seat;
• an actuator comprising a stationary control part for receiving control signals and a moving part, the said stationary part applying to the moving part a force which corresponds to the control signal;
• first rigid means of connection extending in the direction of travel so as to connect the said moving part of the actuator to the said valve shutter element;
• a mechanical stop;
• a member 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 for dynamically connecting one of the faces of the said valve shutter element to the second end of the said compressible member.
