Patent ID: 11927973

Abstract:
A fluid control device includes a slide valve movable in a chamber along an axis between a closed position, in which the slide valve is pressed axially against a fixed seat, and an open position, in which the slide valve is axially separated from the seat and a thermomechanical actuator, which is able to drive the slide valve depending on the temperature of the fluid in the chamber and which includes both a thermostatic element, including a fixed piston, and a body forming a heat-sensitive part of the thermomechanical actuator, arranged inside the chamber The piston being mounted with the ability to move along the axis on the body so that the piston deploys against the body when the thermally expandable material expands, and a return spring, interposed axially between the casing and the body so as to retract the piston away from the body when the thermally expandable material contracts.
