Abstract:
An EGR valve for recirculating engine exhaust gases comprising a body including a housing containing an actuator, an inlet port for receiving exhaust gases, an outlet port for delivering exhaust gases, a valve mechanism comprising a valve element that is selectively positionable along an axis relative to a valve seat to control the flow of exhaust gases from the inlet port to the outlet port, a mount for mounting the EGR valve comprising an annular wall transverse to the axis and having an inner margin circumscribing a hole, the housing comprising a wall seating on the transverse wall of the mount and comprising a hole aligned with the hole in the transverse wall of the mount, and a shaft passing from the actuator, through the aligned holes, to the valve element, including a bearing guide member passing though the aligned holes and guiding the shaft as the shaft passes through the aligned holes, and further including a tubular wall extending axially from the aligned holes in a direction away from the actuator, the shaft exiting the bearing guide member to pass axially through the tubular wall in inwardly spaced relation to the tubular wall.
