Embodiment Construction

[0028] The engine control valve according to the invention may, for example, be an EGR valve, which regulates the flow rate of gases through the circuit connecting the exhaust circuit to the intake circuit of the vehicle's internal combustion engine.

[0029]The engine control valve according to the invention employs a subsection 1 and three gaskets 2, 3, 4 intended to be inserted between two metal castings of the main part of the valve. The subsection 1 comprises a central axis of rotation 5 and a main subsection 6 and a subsection 6, said sections 6, 7 being arranged on either side of said pin 5, in continuation of each other. The two parts 6, 7 have a small thickness and are rigidly fastened together. The general outline of the subsection 1 delimited by these two parts 6 , 7 is substantially rectangular, each of said parts 6 , 7 also having a rectangular shape.

[0030] The rotor pin 5 is offset with respect to a plane comprising the two parts 6, 7 and is located at the en...

Abstract

The present invention relates to a sealed engine control valve device comprising a main body portion defining an internal conduit and a rotatably movable subsection (1) capable of sealing and sealing in an open position allowing gas flow into the conduit Rotating between closed positions of the conduit, the valve comprises a first system (2, 4) for sealing the conduit against the outside of the body part, and a second system (3) Separate from the first system and ensure that the subsection (1) is sealed when in its closed position.

Description

technical field [0001] The present invention relates to a sealed engine control valve device. A valve of this type may, for example, be fitted in the gas supply circuit of a vehicle's internal combustion engine to regulate the flow rate of EGR (exhaust gas recirculation) gases in the circuit, making it possible to suck in a portion of the exhaust gases leaving the engine in order to transfer them in the Reinjection upstream of said engine. The operating principle of this type of valve is based on the controlled rotation of a section movable from a fully open position (for allowing the passage of gas) to a closed position (for blocking this passage). The subject of the invention is an engine control valve with improved sealing. Background technique [0002] The engine control valve thus has a subsection mounted in rotation on a central axis of rotation. The subsections may include main subsections and subsections separated by the pin. When the subsection is in the closed ...
