Abstract: A mounting bracket mechanism and system for mounting a solenoid operated valve, such as an EGR valve, to a vehicle. A strap-type mounting bracket is positioned over the valve and secured to the engine or other vehicle component with a plurality of bolts or other fasteners. A curved recess or groove is provided in an engine component or surface, or a spacer member is positioned between the valve and the engine component or surface in order to maximize surface contact and thus heat transfer between the valve and the vehicle. Spring tab members can be positioned on the mounting bracket in order to minimize vibration of the valve in the vehicle and more securely fix it in place. The mounting bracket, spacer member, and valve can be assembled together as a modular preassembly for mounting to the engine.

Abstract: A closed-loop controlled system solenoid actuated EGR valve includes an engine mount for attachment to a vehicle engine, a valve housing to which the engine mount is attached, a motor housing positioned above the valve housing, and a sensor housing. The valve housing includes a valve inlet adapted to receive engine exhaust gas and a valve outlet which communicates the engine exhaust gas from the valve inlet to an engine intake system. The motor housing has a bobbin, an armature, and a valve stem disposed in a bore formed therein. The valve stem is in communication with a plunger extending from the sensor housing to monitor the position of the valve stem with respect to the valve seat. A guide bearing is positioned in the housing to guide the armature while a valve stem bearing is positioned in the valve housing to contact and position the valve stem with respect to the valve seat while a valve opening is being closed.
