Control valve to return exhaust gas to fresh gas in IC engines consists of two parts connected to separate guide systems with tubes for returned exhaust

摘要

The valve has a fresh gas-sided first part and an exhaust-sided second part, each with passage bores to block/free exhaust flow. The passages (5) of the first valve part (4) are connected to a first guide system (6) with separate tubes (7) for returned exhaust, which are associated with individual cylinders. The passages (5') of the second valve part (4') are connected to a second similar guide system (6') with exhaust tubes (7'). The valve parts are relatively moveable.
