A new and improved EGR valve having a valve body having an inlet port and an outlet port with a valve member moveably supported within the valve body between the inlet and outlet ports. A control cap is connected to the valve body and contains an integrated sensor that is used to provide an engine control module with pressure readings from the valve body and the interior portion of the cap. Additionally the cap also has an integrated zero emissions system that is capable of preventing the release of harmful chemicals into the atmosphere.

Exhaust gas recirculation (EGR) module having sensor integrated into cover (ESM)

The valve has a solenoid actuator and a position sensor providing an electric signal of the position of the solenoid armature. The solenoid is an electromagnet coil disposed on a plastic bobbin. The magnetic circuit contains a stator member having a flange disposed against a flange of the bobbin, and the position sensor has a plastic housing having a base that captures the stator member flange against the bobbin flange. The stator member flange contains apertures through which non-metallic material that joins with the bobbin flange passes to join with the position sensor housing base, thereby uniting the bobbin and the position sensor housing in assembly capturing the stator member flange. The assembly may be fabricated by an insert molding method or a method in which joining material is melted.

Electric exhaust gas recirculation valve with integral position sensor and method of making

An internal combustion engine cylinder head (,) has an exterior wall that contains a walled compartment (,). A wall of that compartment is exposed to an internal coolant passage (,) through which liquid coolant circulates. An exhaust gas passageway (,) running through the compartment has an exhaust gas entrance (,) into the compartment and an exhaust gas exit (,) from the compartment. The compartment comprises a receptacle (,) that intersects the exhaust gas passageway between the entrance and the exit. An EGR valve (,) disposed on the exterior wall comprises a base (,) that has an inlet port (,) and an outlet port (,) and that is disposed within the receptacle with the inlet port open to the entrance via the passageway and the outlet port open to the exit via the passageway. As hot exhaust gas is recirculated, coolant that circulates through the coolant passage aids in limiting peak temperatures to which the valve may be subjected.
