Abstract: A device for monitoring circulation of a fluid at a first opening includes a housing through which fluid passes, the first opening to be monitored, at least a second opening that empties into a chamber of the housing, and a sealing element that can shift or be moved, in a reversible manner, from one closed position in which it seals the first opening to at least one open position in which it releases the opening and allows fluid circulation. The sealing element is capable of being deployed in the chamber, and its movement is controlled by at least one activating element. The sealing element includes a moving body that forms a piston whose one end part is configured to seal the first opening and a portion of membrane is sandwiched between the end part of the moving body and at least the edge that forms a seat of the first opening.

Abstract: A water out-let box comprising a regulating thermostat principally made up of a valve to block an opening of a passage emerging in the box, the valve being stressed against its seat, formed by the peripheral edge of the above-mentioned opening, by an elastic loading means and moved away from the seat by a pressure means that reacts to heat, the means with opposed actions resting, directly or indirectly, on a stress-absorbing clamp which also ensures that the thermostat is mounted and positioned in cooperation with an opposed bearing. Box is produced in a thermoplastic material and comprises, on the internal face of its constitutive wall (1?), at least two internal protrusions (10, 10?) providing permanent support surfaces (10?) for the clamp (9) of the thermostat (2), before and after installation of the box (1).
