ABSTRACT:
A valve for combining exhaust gas from an engine combustion chamber with engine intake gases. The valve includes a valve body having a gas inlet and a gas outlet connected by a throughpassage. A flow control member supported by the valve body regulates flow through the valve body throughpassage. A magnetic drive is supported for movement with respect to the valve body and coupled to the flow control member to regulate flow in the throughpassage. An electronically actuated field-generating solenoid moves the magnetic drive member to control flow through the valve body. The solenoid and a sensor for monitoring a position of the magnetic drive are supported within a plastic molded housing. The plastic housing also partially encapsulates a pole piece that forms a magnetic circuit in combination with the magnetic drive.
