Embodiment Construction

[0105] The invention relates to a fluid circulation valve for a motor vehicle. figure 1 Such a fluid recirculation control valve 10 is depicted, configured to control the flow of exhaust gas recirculated to the engine intake.

[0106] The exhaust gas recirculation valve can be of the "high pressure" type, meaning that the exhaust gas is between the point on the exhaust circuit upstream of the turbocharger's turbine and the point on the engine intake circuit downstream of the turbocharger between recirculation.

[0107] The valve 10 includes a valve body 12 delimiting a gas circulation conduit 14 . The duct extends along a longitudinal axis denoted A.

[0108] The valve body 12 may be made of metal such as steel. Preferably, the valve body 12 is made of aluminum or aluminum alloy.

[0109] The valve 10 comprises a shut-off member 16, in this case a plug, movable in translation between two end positions. One of the end positions of the shut-off member corresponds to a posit...

Abstract

The invention relates to an actuator (30), in particular intended for being integrated into a valve for a motor vehicle engine, comprising: a toothed sector (34) rotatably mobile about an axis of rotation; a rod (32) centred on the axis of rotation; and a damping means (36) comprising at least one pair of abutments (38), at least one abutment (40) being rigidly connected to the toothed sector (34)and at least one abutment (42) being rigidly connected to the rod (32), and wherein at least one abutment (40, 42) of the pair of abutments (38) is designed to absorb the relative movements between the toothed sector (34) and the rod (32).

Description

technical field [0001] The invention relates to an actuator, in particular intended to be integrated in a valve for a motor vehicle engine, and a fluid circulation valve comprising such an actuator. [0002] In particular, the field of the invention is devices for supplying internal combustion engines, in particular motor vehicles, such as air metering valves or actuators involved in the operation of the internal combustion engine and arranged in the air circuit of the internal combustion engine. In the sense of the present invention, the term "internal combustion engine air circuit" refers to the circuit between the intake air inlet and the exhaust air outlet of the internal combustion engine. The valve may be placed in an intake circuit, an exhaust circuit, or a recirculation circuit ("EGR") through which exhaust gas is fed back into the intake passage. Background technique [0003] Valves for controlling the flow of gas are known, comprising a body with a fluid passage c...
