Abstract: An electrically controlled EGR valve comprising: a valve stem (64), eccentrically positioned from an axis of rotation and movable in a substantially axial manner relative to a valve seat (84); a poppet valve (70) carried by the valve stem for closing the valve seat (84); a first shaft (52) eccentrically positioned relative to the axis of rotation and engagably connected to one end of the valve stem (64), and an electrically controlled actuator such as a torque motor (30) for rotating the first shaft (52) about the axis to cause the valve stem to move.

Abstract: A fan (10) adapted to be driven by an electrical motor (12), the motor of the type having openings (14) to permit the flow of air therethrough to cool internal components of the motor. The fan comprising a cup-shaped hub (20) adapted to be driven by the motor and including a plurality of arcuately shaped webs (44, 70) for inducing the flow through the motor and through a plurality of openings (40) formed in a axially extending wall (28) of the hub (20).

Abstract: A throttle assembly (10) for an engine comprising: a primary throttle plate (16) rotatably mounted on a first shaft (18); linkage (22) for rotating the first shaft (18) in response to operator demand; a second throttle plate (42) received within a cut-out (30) formed in the first throttle plate and rotatably mounted relative to the first shaft; and an actuator (50) for rotating the second throttle plate relative to the first throttle plate to adjust the flow area of a second flow passage formed between the first and second throttle plates.

Abstract: An air cleaner and method of making same, the air cleaner comprises: a one piece, moulded housing, including domed first and second outer portions integrally formed about a common circumferential first edge, defining therein a chamber, an inlet and an outlet extending therefrom in communication with the chamber. A panel filter is secured within the housing, during the moulding thereof, at the common edge for dividing the chamber into first and second aerodynamically shaped compartments in communication with the inlet and outlet respectively.

Abstract: A solenoid valve comprising: a stator; a coil responsive to current into thereto, and magnetically connected to the stator. The coil characterized such that its resistance changes with temperature to increase or decrease, as the case may be to vary the amount of flux generated. A valve seat positioned about one end of the stator defining a valve seating surface positioned at a predetermined distance for the one end and a flat armature movable relative to the valve seat and when seated thereon is spaced from the one end. The armature fabricated of a bi-metallic, thermally responsive element for causing a portion of such armature to move closer to or farther from the stator to vary the distance between such portion on the one end as a function of temperature to compensate for the changes in magnetic flux.

Abstract: A valve (10) comprising a plurality of passages (22,24), and an annular sealing area (30) in communication with one of the passages. The valve also includes a diaphragm (50), movably supported relative to the sealing area (30) in response to a force differential applied thereacross; including a thin, planar, flexible, non-metallic membrane (92) for sealably engaging against the sealing area.

Abstract: A drive (10) having high speed and low speed modes of operation comprising an input shaft (20), a planetary gear set (12) drivingly connected to the input shaft (20) comprising a sun gear (14) disposed about the input shaft, a brake (46) for preventing the ring gear from rotating during the low speed mode; an output pulley (50) linked to and rotatably with the planetary gear set (12), a clutch (60) for connecting the output pulley (50) to the input shaft (20) during the high speed mode and for disengaging the output pulley from the input shaft during the low speed mode, and bellows (90) for moving the clutch (60) into and out from engagement during the high and low speed modes.

Abstract: A vapor control valve (12) and system therefor for controlling fuel tank (14) pressure and for purging hydrocarbons from a storage canister (16) comprising a single electrical coil (44) responsive to control signals, wound about a carrier or bobbin (34) including a central passage (36) and means for dividing said central passage into first (40) and second (42) axially aligned portions; a first piston (60) slidably received within said central passage at said first portion (40); a second piston (80) slidably received within said central passage at said first portion (42); a first valve seat (132) for receiving said first piston; a second valve seat (106) for receiving said second piston, a first spring (66) for biasing said first piston into said first valve seat; a second spring (90) for biasing said second piston into said second valve seat, wherein the spring constant of said first spring is less than the spring constant of said second spring.
