摘要： 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.

摘要： A bellows valve assembly installed in a fluid pathway includes a valve body, a bellows housing positioned adjacent the valve body, and a valve actuator. The valve body is equipped with an inlet, an outlet, a valve bore positioned between the inlet and the outlet, and a valve seat disposed between the inlet and the outlet. A valve closure element having a sealing surface is positioned in the valve bore and is engageable with the valve seat to restrict fluid flow through the valve bore. The valve closure element also has a valve stem that extends from the valve bore through the bellows housing. The valve stem has a lower portion characterized by a first average diameter and an upper portion characterized by a second average diameter that is at least 25% smaller than the first average diameter. The actuator is engageable with the upper portion of the valve stem to move the sealing surface relative to the valve seat. Further, a pressure-balanced bellows assembly is positioned in the bellows housing and has at least one section secured to the valve stem such that the bellows assembly surrounds a portion of said valve stem. The bellows assembly divides the bellows housing into a first chamber defined inside of the bellows assembly and a second chamber defined outside of the bellows assembly. A first passageway is provided to extend between the first chamber and a location in the fluid pathway downstream of the valve seat so as to communicate the fluid pressure downstream of the valve seat to the first chamber. Further, a second fluid passageway is provided to extend between the second chamber and a location in the fluid pathway upstream of the valve seat so as to communicate the fluid pressure upstream of the valve seat to the second chamber.
