Exhaust gas recirculation device for e.g. vehicle's diesel engine, has cylindrical inner body including traversing passage allowing communication between low pressure inlet and outlet orifices when inner body occupies low pressure position

摘要

The device has a hollow body (110) provided with high pressure inlet and outlet orifices (112, 116), and low pressure inlet and outlet orifices (114, 118). A cylindrical inner body (130) has a rectilinear traversing passage (134) that allows communication between high pressure inlet and outlet orifices when the inner body occupies a high pressure position, and allows communication between the low pressure inlet and outlet orifices when the inner body occupies a low pressure position. An independent claim is also included for an internal combustion engine comprising an exhaust gas recycling circuit.
