An exhaust gas recirculation valve

An exhaust gas recirculation valve

Disclosed is an exhaust gas recirculation (EGR) valve assembly for selectively opening or closing exhaust gas flow. The valve assembly may be used to control the flow of exhaust gas from a source, such as an exhaust manifold 225, to an EGR cooler 310 or to an EGR cooler bypass passage 310a or both....

description Disclosed is an exhaust gas recirculation (EGR) valve assembly for selectively opening or closing exhaust gas flow. The valve assembly may be used to control the flow of exhaust gas from a source, such as an exhaust manifold 225, to an EGR cooler 310 or to an EGR cooler bypass passage 310a or both. The valve arrangement comprises a single by-pass valve 320a and a housing 1 having inlet F1 for the exhaust gas, a first outlet F2 connected to the EGR cooler passage 310 and a second outlet F3 connected to the EGR cooler bypass passage 310a. The single by-pass valve comprises at least a shut-off member 2, possibly in the form a piston having a shaft 3 and a head 4 which may be slid to at least partially cover either the first or second outlets or moved to a position in which it covers neither outlet.
