Embodiment Construction

[0022] now refer to figure 2 , which shows an engine control valve 100 according to the invention comprising a valve flap 112 mounted in a pivotal manner about an axis of rotation 114 . The valve flap 112 includes a first portion 112A and a second portion 112B interconnected at an axis of rotation 114 . The first portion 112A and the second portion 112B of the valve flap 112 are parallelepiped-shaped in cross-section. The first portion of the valve flap 112 includes opposed first and second planar surfaces 118A, 118B. Similarly, the second portion 112B of the valve flap 112 includes opposed first and second planar surfaces 120A, 120B. One end of the first portion 112A of the valve flap 112 is arranged on the shaft 114 such that its first surface 118A is located opposite the shaft 114 with respect to its second surface 118B. The second portion 112B of the valve flap 112 bears at one end by its first planar surface 120A against the first planar surface 118A of the first port...

Abstract

The invention relates to an engine control valve (100), comprising a flap (112) rotatably mounted in a valve body (126) about an axis (114) separating said flap into a first portion (112A) and a second portion (112B), said flap (112) being capable of engaging with sealing means supported by the valve body (126) in a closed position in order to halt the flow of a fluid through said flap, for which the first portion (112A) of the flap (112) sealingly engages with first sealing means (122A) and the second portion (112B) of the flap (112) sealingly engages with second sealing means (124B). According to the invention, the first sealing means (122A) and the second sealing means (124B) are mounted securely so as to slide along the valve body (126).

Description

technical field [0001] The invention relates to an engine control valve, as well as an engine and a motor vehicle comprising such a valve. Background technique [0002] Traditionally, current engines include a decontamination system by means of exhaust gas recirculation, consisting of ducts that allow diversion of the exhaust gases towards the intake, equipped with a heat exchange for cooling the combusted gases The exhaust gas recirculation (RGE, or English EGR: Exhaust Gas Recirculation) valve, the opening of the valve is controlled by the engine control calculator to adjust the reintroduction of the burned gas in the direction of the intake port. gas flow rate. [0003] The operating principle of this type of valve is thus based on the controlled rotation of a valve flap which can be switched from a fully open position for letting the exhaust gas flow through to a closed position for preventing this passage. [0004] Thus, the engine control valve has a valve flap which...
