Abstract: Valve unit with a sliding throttle-chamber, comprising a valve body with an exchange or distribution chamber adapted to receive a sliding throttle-chamber of which the position of translation in the chamber defines ways of fluid communication between a primary inlet opening and at least two secondary outlet openings that can be selectively blocked or released by said throttle-chamber; the sliding throttle-chamber has a composite structure and consists of a first part controlling the fluid communication of said, at least, one secondary or radial outlet opening with the chamber and a second part controlling the fluid communication of the secondary or axial outlet opening with the chamber, the two parts of the throttle-chamber being linked together by a driving link in translation with a dead or non-driving area between the two extreme translation positions of said throttle-chamber.

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.
