The invention relates to a double distributor for distributing the intake fluid of an internal combustion engine and controlling the temperature thereof, comprising a body () in which first and second channels for circulating said intake fluid are arranged, first () and second () shutters being positioned in said channels in order to distribute the flow passing through said channels, said distributor also including a motor () for actuating said shutters and kinematics simultaneously actuating the first and second shutters according to a movement law in response to an actuation of said motor, said kinematics comprising an inactive position in which said shutters are positioned when no force is supplied by said actuator motor, characterized in that said kinematics are configured such that said shutters can strictly follow said movement law when actuated by the motor from said inactive position without returning to said position.

Distributor having two channels and a single motor operating in a single direction

The invention relates to a distribution module () for distributing an inlet mixture to at least two cylinders of a heat engine, this inlet mixture selectively comprising:&#x2014;cooled inlet air, or&#x2014;non-cooled inlet air, or&#x2014;recirculation gas, or&#x2014;a combination of at least two of the above elements, the module () comprising:&#x2014;a first inlet () for conveying cooled inlet air into the module (),&#x2014;a second inlet () for conveying non-cooled inlet air into the module (),&#x2014;a third inlet () for conveying recirculation gas into the module (), the module being arranged to distribute the inlet mixture substantially equally between said at least two cylinders.

Distribution module for distributing an inlet mixture

The invention pertains to a three-way valve (), particularly one intended to be used in an air intake circuit of a motor vehicle, comprising: a body () delimiting a first (), a second (), and a third () conduit, said conduits opening into a shared inner space (), a first flap () capable of being moved to obstruct the first conduit, a second flap () capable of being moved to selectively obstruct either the second or the third conduit, a single actuator being arranged to selectively move at least one of the first and second flaps.

Valve with two flaps placed serially and actuated by a common motor

The valve comprises: a body () through which the fluid flows; and a controllable rotary closure means () disposed in the body, which can be rotated in relation to the body in order to occupy different angular positions. Advantageously, the body () comprises an inner cylindrical housing () having a circular cross-section, and the closure means () comprises one portion () arranged on a plane inclined in relation to the cylindrical housing () and co-operating with the side wall () of the housing by means of a peripheral generatrix, such as to provide a sealed contact between the closure means () and the body () in at least one angular position.

Valve for controlling a flow of fluid, including a rotary closure means

The invention relates to a fluid flow valve, particularly for a motor vehicle. Said fluid flow valve comprises a body (), capable of having said fluid pass therethrough; and a sealing means (), placed in said body, capable of occupying different angular positions by rotation of said sealing means () relative to said body (). Said sealing means () is configured so as to enable, in a first angular position, the fluid to pass from a first inlet () to a first outlet () of the valve and from a second inlet () to a second outlet () of the valve, and, in a second angular position, to enable the fluid to pass from the first inlet () to the second outlet () through the body (). Said sealing means () is also configured so as to ensure a gradual closing of the first inlet ().

Fluid flow valve, particularly for a motor vehicle, and a temperature regulation device including one such valve

The invention relates to a fluid circulation valve, notably for a motor vehicle, comprising a body () and a shutoff element () able, by rotation of said element () with respect to said body (), to occupy various angular positions, said body () having a first (), a second (), a third () and a fourth () inlet/outlet. Said valve is configured so that it: &#x2014;in a first of said angular positions allows fluid to circulate from the first () to the second () inlet/outlet, &#x2014;in a second of said angular positions allows fluid to circulate from the first () to the third () inlet/outlet, and from the fourth () to the second inlet/outlet (), &#x2014;in a third of said angular positions allows fluid to circulate from the first () to the fourth inlet/outlet () and from the third () to the second () inlet/outlet.

Fluid circulation valve, notably for a motor vehicle, and thermal conditioning device comprising such a valve

A device for dosing inlet fluid in an engine and for regulating the temperature thereof is disclosed. The device has a dosing body on which a first and a second circulation channel are arranged. First and second movable flow dosage flaps are arranged in the circulation channels. The dosing body also includes an actuator motor and a kinematic capable of actuating the first and/or the second flap. The device additionally includes first and second tubes, at least one of the tubes having a means for modifying the temperature of the fluid. The kinematic is shaped so as to position at rest, if flap actuation is lost, the first flap of the cool channel being then in a fully open position and the second flap of the hot channel being then in a fully closed position.

Secured double-channel controlling device for automobile engine

The invention relates to a double distributor for distributing the intake fluid of an engine, comprising a body in which first and second flow channels are arranged, first and second movable shutters being positioned in said flow channels, said distributor also including an actuator motor and kinematics for simultaneously actuating the first and second shutter, characterized in that the kinematics are arranged so as to distribute the flow passing through the first output channel by rotating the first shutter, provide proportional distribution via the two output channels by simultaneously rotating the two shutters, and distribute the flow passing through the second output channel by rotating the second shutter.

Throttle having two channels with control via each channel

The invention relates to a fluid circulation valve comprising a body () through which said fluid can pass, and a first and second shutoff means ('), arranged in series, in the direction of flow of the fluid, in said body and each able, by rotation of said means (&#x2032;) with respect to said body () to occupy various angular positions, said valve further comprising a drive train allowing said shutoff means (&#x2032;) to be driven off one and the same actuating motor, said valve being configured to: &#x2014;over a first angular range of said first shutoff means () allow said fluid to be metered in a first outlet port () of said valve, said second shutoff means (&#x2032;) being in a position in which said first port () is wide open, &#x2014;over a second angular range of said first shutoff means () allow said fluid to be metered in a second outlet port () of said valve, said second shutoff means (&#x2032;) being in a second position in which said second port () is wide open.

Fluid circulation valve

A valve able to control an exhaust gas recirculation system of an internal combustion engine equipped with a turbine installed in an exhaust circuit of the internal combustion engine, is disclosed. The valve includes a body through which a first stream of exhaust gas tapped off upstream of the turbine can flow and through which a second stream of exhaust gas tapped off downstream of the turbine can flow. The valve is configured to control the flow of the first and second streams of exhaust gas through the valve body.

Control valve for an internal combustion engine exhaust gas recirculation system

A gas intake device for letting gases into an inlet volume of a cylinder head of a motor vehicle combustion engine includes a valve () for supplying the cylinder head with gas, this valve communicating with the inlet volume of the cylinder head directly and indirectly via a heat exchanger (). The valve () and the heat exchanger () are mounted on a plate () intended to be mounted directly on the cylinder head. The device is compact and relatively insensitive to vibration.
