Abstract: An exhaust bypass valve assembly for an internal combustion engine includes an exhaust bypass valve having valve structure coupled to a rotatable shaft such that rotation of the shaft moves the valve structure between opened and closed positions. An actuator is disposed remotely from the bypass valve for selectively causing rotation of the shaft associated with the valve structure in opposing directions. Linkage structure is connected between the actuator and the shaft to transfer motion of actuator to the shaft.

Abstract: A bypass valve cartridge (10) is provided for permitting exhaust gas recirculation (EGR) flow to bypass a cooler port of a cooler of a vehicle. The cartridge (10) includes housing structure (11) constructed and arranged to be inserted into and mounted in a portion of a cooler (30). Flapper structure (22) is disposed in the housing structure and movable between a first position permitting EGR flow to pass to a cooler port (34) and a second position substantially preventing EGR flow to pass to the cooler port.

Abstract: An emission control valve is operated by an electric actuator that has an electric coil, stator structure, and a positioning mechanism, including an armature that is selectively positionable along an axis, for selectively positioning a valve element. The stator structure is separated from the armature by an air gap that includes a non-ferromagnetic guide sleeve that is in surface-to-surface contact with the armature for guiding armature motion along the axis. The guide sleeve and the stator structure are in surface-to-surface contact for mutually concentricity with the axis. Along a region of mutual overlapping a minimum air gap is provided between the guide sleeve and the stator structure by radial spacing between the stator structure and the guide sleeve. Various embodiments are disclosed.

Abstract: A connection and a method of providing a connection includes a fluid tight communication between a valve and a tube. The valve includes a first surface, a second surface, a cavity, and an aperture extending through the valve between the first and second surfaces. The tube includes a first portion, a second portion and a third portion between the first and second portions. The first portion penetrates the first surface and extends through the aperture into the cavity. The third portion is deformed so as to engage the second surface.

Abstract: A slider assembly for use in a linear or rotary position sensor having a board that includes at least one ink strip. The slider assembly includes a housing for attachment to an object whose position is being detected. The housing includes standoffs for contacting portions of the board which are adjacent the ink strip. An arm extends the housing, wherein the arm includes finger elements which contact the ink strip. The assembly further includes a spring for biasing the standoffs against the board to then bias the finger elements against the ink strip so as to provide a predetermined contact pressure.

Abstract: A slider assembly for use in a linear or rotary position sensor having a board that includes ink strips. The slider assembly includes a base element having a plunger for attachment to an object whose position is being detected. Finger elements extend from the base element, wherein the finger elements contact the ink strips and are biased against the ink strips. A spring device having first and second spring elements is also included, wherein the first and second spring elements contact portions of the board that do not include the ink strips. The contact portions are biased against the board to reduce relative motion between the finger elements and the ink strips.

Abstract: An internal combustion engine exhaust emission control system has a module for conveying exhaust gas from an engine exhaust system to an engine intake system. A valve selectively restricts the flow path. A pressure sensing passage communicates a pressure sensing port of a pressure sensor to the flow path. The pressure sensing passage comprises a tube having an end portion passing through a through-hole in a side wall of the flow path. In one embodiment, an open free end of the tube is disposed within the flow path in spaced relation to the side wall opposite an orifice that creates a pressure drop for obtaining a flow measurement using pressure sensed via the tube as one input. In another embodiment, the open free end of the tube is disposed flush with the side wall opposite a nozzle.
