The invention relates to a device for controlling the ingress of intake gases to an engine, notably an internal combustion vehicle engine comprising cylinders, said device taking the form of a compartmentalized guide piece (), each compartment () comprising a main duct () and a secondary duct () for gas, characterized in that the control device comprises a multitude of modules () each one delimiting a main duct () and a secondary duct (), and in that the modules () constitute separate components designed to be fitted together.

Gas intake system for a vehicle engine

The invention relates to a module () for supplying gas to a motor vehicle, comprising a double dispenser (), a charge air cooler (), and an intake box () connecting said double dispenser () to said cooler (), the double dispenser () comprising a first outlet () intended to lead into the intake box () and a second outlet intended to lead toward the outside of said module ().

Module for supplying gas to a motor vehicle

The invention relates to an interface part () between a motor vehicle engine head and a heat exchanger (), the interface part () comprising a first opening for the flow of a first gas. According to the invention, the first opening has a profile capable of engaging with a valve element comprising a movable portion () of the valve (), with a view to at least partially sealing the first opening by means of said movable portion (). The invention also relates to an assembly of such an interface part and a valve, and to a gas supply module for an engine comprising such an assembly. The invention is applicable, in particular, to the automotive field.

Interface part between a motor vehicle engine head and a heat exchanger

The invention relates to a gas supply module () for an engine, comprising a heat exchanger () capable of cooling gases for the intake thereof in an intake space of a cylinder head of the engine, and a gas supply valve () capable of directing said gases toward the intake space of said cylinder head and/or through said heat exchanger (), said module () further comprising an interface element () closing said intake space of said cylinder head. According to the invention, said interface element () and said valve () are shaped such that said valve () can be attached to said cylinder head via at least a first attachment means extending through at least the interface element (). The invention also relates to an assembly of an engine cylinder head and such a module, and to a motor vehicle engine comprising such an assembly. The invention can particularly be used in the field of motor vehicles.

Gas supply module for a motor vehicle engine, assembly of an engine cylinder head and such a module, and motor vehicle engine comprising such a module

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.

Gas intake device

A three-way valve () with two flaps () respectively positioned in two of the three paths () of the valve and comprising means (-) for controlling and actuating the flaps () to make them pivot from one to the other of two positions in which the paths () are either open or closed. Single control means () are provided for both flaps (), and there are actuating means (-) designed to be controlled by the single control means () and to actuate the two flaps () with a temporal phase shift.

Device for air intake of a heat engine including:

Air intake device for a heat engine with a cooled main circulation system and a bypass system equipped with a heating mechanism

A valve including a body delimiting an inlet duct opening into a first and second outlet duct. The body includes a first butterfly valve element and a second butterfly valve element. The first butterfly valve element is mounted on a first transmission gearwheel connected to a drive motor and is movable into two closed positions on either side of an open position of the first duct. The first transmission gearwheel is connected to a second transmission gearwheel, on which the second butterfly valve element is connected by a one-way positive drive element. When the first butterfly valve element is moved from an open position to one of the two closed positions in the first duct, the second butterfly valve element is driven from a closed position to an open position of the second duct. The valve includes a member for returning the second butterfly valve element to the closed position.
