A slide-valve device sliding in a predetermined axial direction, includes a valve body having two chambers, the first chamber including a lateral fluid-intake opening and a fluid-outlet opening provided with a normally closed, conditionally opening plug device, the second chamber including first and second lateral fluid-outlet openings, mutually offset in the axial direction. Two inner regions of the second chamber are arranged contiguously in the axial direction and communicate with one another via an opening or an internal passage, and in that the sliding drawer includes a first plug member suitable for selectively plugging the communication opening or the internal communication passage or opening between the two regions and a second plugging member suitable for preventing fluid communication between the second lateral fluid-outlet opening of the second chamber and a first region of the second chamber, within a predetermined range of translation of the sliding drawer.

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.

A water outlet chamber-type regulating device includes a chamber component having an inlet and an outlet for a fluid to be regulated, and including a member for regulating the flow, the member having a valve component translatingly movable and configured to close a passage cross-section between the inlet and the outlet, and is rigidly fixed to a control shaft. The chamber component includes at least one opening formed in its lateral wall, and the control shaft carries a second closing component, which is integral in translation with the shaft and is positioned on the shaft and has a shape that is configured to regulate the flow of water passing through the opening as a function of the regulation of the flow in the region of the passage cross-section.

Regulating device of the water outlet chamber type

A cooling circuit comprises a cylinder block and a cylinder head block, these blocks each including cooling elements the form of integrated portions of circuit. The cooling circuit also includes at least a first, a second and a third separate external loops for external recirculation or reinjection mounted in parallel and looped on the integrated cooling elements. A circulating pump is connected fluidically to the integrated cooling element and to the three recirculation loops causing the fluid to circulate in the integrated cooling element and in the three recirculation loops. The at least three recirculation loops offer at least one common fluid node and are at least partially overlapping. A single actuator controls the flow of liquid circulating in the at least three recirculation loops.

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 ('), at least two internal protrusions (&#x2032;) providing permanent support surfaces (&#x2033;) for the clamp () of the thermostat (), before and after installation of the box ().

A pump/valve assembly forming part of a circuit for circulating a liquid fluid has a pump and a proportional-control valve unit () in series with the pump. The valve unit () has a valve (), an electrical actuator () and a position sensor () which are fixed to a movable member (') sealing the valve () for displacement therewith, and control means () controlling the actuator () according to the position of the movable member (&#x2032;) indicated by the sensor () and a reference signal. The valve unit () is subjected to a procedure indexing the position of the movable member (&#x2032;) and setting parameters for the control means () at the beginning of each new operating cycle of the assembly, and the pump () is rotated at a constant speed selected from a limited number of predetermined speeds at least during part of each operating cycle.

The present invention relates to a flap valve device and a regulation assembly comprising such devices. A pivoting flap valve device has a flap body substantially in the form of a disc mounted on a support and control axle, for the regulation of the circulation of a fluid, particularly a liquid, between an upstream conduit portion and a downstream conduit portion. The flap body ( ) is mounted centered on the axle ( ), in that the two conduit portions ( and ) are axially offset relative to each other and in that the internal surfaces ( ) of the opposed offsets resulting from the axial offset or non-alignment of the portions ( and ) constitute bearing surfaces ( ) for two complementary seat portions ( ) for the flap body ( ), located on opposite sides of the axle ( ) carrying the flap body ( ).
