摘要： A contactless control switch (20) for a vehicle for actuating a system between an open and a first closed circuit position is disclosed. The switch includes a housing (22) and a pivot assembly (24) disposed within the housing. The switch also includes a switch actuator (26) having first and second ends. The switch actuator is coupled to the pivot assembly for producing pivoting motion of the switch actuator in response to a force (84) applied to the switch actuator. The switch also includes first and second proximity sensors (80a and 80b) and a first magnet (70). The proximity sensors are disposed within the housing and the first magnet is fastened to the switch actuator second end. The first magnet is adapted to be selectively displaced into and out of close proximity with one of the proximity sensors when the force is applied to the switch actuator. The switch (20) also includes a biasing member (52a and 52b) disposed between the switch actuator and the pivot assembly for biasing the switch actuator into an open circuit position.

摘要： A valve plug is biased inwardly by a spring (90) to close an opening (10) in a cap (2) for a fuel tank filling and venting tube. A valve stem includes a first portion (62) which is engaged by the spring (90) and a second float cage portion (40) that is secured to and extends axially inwardly from the plug. A collapsible retainer (70) is secured to the cage (40) and has an abutment surface (74) which engages an abutment surface (68) on the first portion (62) to hold the cage (40) and the first portion (62) in position relative to each other and to transmit axial forces therebetween. A fusible material ring (88) is positioned radially between the retainer (70) and the cage (40) to prevent the retainer (70) from collapsing. At elevated temperatures, the ring (88) melts to allow the retainer (70) to collapse, the cage (40) and first stem portion (62) to separate from each other, and the valve plug and cage (40) to move away from the opening (10).

摘要： A fill tube (12) leading into a fuel tank (10) is provided with a normally closed closure door (20) and a fill nozzle seal (24, 26, 30) spaced outwardly of the closure door (20). When liquid fuel is to be added to the fuel tank (10) a fill nozzle (32) is inserted through the fill nozzle seal (24, 26, 30). A seal element (30) engages the outside diameter of the fill nozzle (32) and seals against vapor leakage between the seal element (30) and the fill nozzle (32). Further insertion of the fill nozzle (32) into the fill tube (12) moves the end of the fill nozzle (32) against the closure door (20) opening the closure door (20). When this happens, fuel vapor within the fuel tank (10) flows through an opening (18) that is normally closed by the closure door (20), to and through an outlet (36) leading from a chamber (34) that is between the fill nozzle seal (24, 26, 30) and the closure door (20). The vapor flows from the chamber (34) into and through a vapor recovery passageway which leads to a vapor storage device (38). Liquid fuel being introduced into the fuel tank (10) displaces vapor from the fuel tank (10) through the vapor recovery passageway to the vapor storage device (38).

摘要： Separate valve bodies (16, 18) are connected by a sleeve (24). The joint (26) between the first body (16) and the sleeve (24) is detachable by bending forces and resistant to tension forces. The joint (32) between the second body (18) and the sleeve (24) is detachable by tension forces and resistant to bending forces. Each joint (26, 32) includes an annular groove (28, 34) on the valve body (16, 18) and portions (30, 36) of the sleeve (24) extending radially into the groove (28, 34). Each valve body (16, 18) has a valve element (44) that moves axially inwardly to close the flow passage (42) when one of the joints (26, 31) is detached. The valve element (44) is normally retained in an open position by a ball detent (84). A projection (82) carried by the confronting valve body (16, 18) holds the ball (84) in a groove (62) on the element's shaft portion (56). In a vehicle (2) having two fuel tanks (4) connected by a crossover line (10), a valve (14) is positioned at each end of the line (10) between the line (10) and the associated tank (4).

摘要： A piston (36) divides the valve interior into a main chamber (38) and a sensing chamber (40). A fixed valve seat (26) sealingly engages the piston (36) to close communication between the chambers (38, 40). The seat (26) is carried by an axial stem (20) which extends through an opening (42) in the piston (36). The valve inlet (14) extends through a passageway (22) in the stem (20) into the main chamber (38). An outlet (28) is formed in the main chamber (38). A valve element (62) closes the outlet (28). When pressure is higher in the main chamber (38) than in the sensing chamber (40), the piston moves toward the sensing chamber (40) to open communication between the chambers (38, 40). When there is a pressure drop in the main chamber (38), the piston (36) moves toward the main chamber (38) to open communication between the chambers ( 38, 40) and move the valve element (62) into an open position. A flange (46) caried by the piston (36) engages a flange (80) formed on a hat-shaped retainer (72) to which the valve element (62) is attached. The valve (8) preferably has a manual drain lever (88).

摘要： A vapor vent valve (16) comprises a housing (28) the interior of which is divided into two fluid chambers (32, 34) by a movable wall (30). The first chamber (32) provides a closable junction in the vapor recovery passageway (18, 20) between a liquid fuel tank (10) and a vapor storage canister (22). The second chamber (34) has a combined inlet/outlet (38) which is interconnected with a signal pressure region (44) in the fuel tank fill tube (12) adjacent to the fill tube cap (14). A valve plug (36) is fixed to the movable wall (30) so that when the pressure in the first fluid chamber (32), the signal pressure region (44 ) and the second fluid chamber (32) are substantially equivalent, the valve plug (36) is positioned to close the vapor recovery passageway (18, 20). When the closure cap (14) is removed, a fill nozzle (46) is inserted into the fill tube (12 ), and liquid fuel is being delivered into the fuel tank (10), the pressure in the signal pressure region (44) and the second fluid chamber (32) decreases relative to that in the tank (10) and the first fluid chamber (34), the movable wall (30) is displaced from its normal position causing the valve plug (36) to open the vapor recovery passageway (18, 20) between the fuel tank (10) and the vapor storage canister (22).

摘要： A gas vent orifice (78, 148) is located within a gas vent passageway. A closure ball (80, 154) is located upstream of the orifice (78, 148). A piston (66, 166) is located downstream of the orifice (78, 148). The piston (66, 166) includes a projection (76, 170) which projects into the orifice (78, 148), for dislodging the closure ball (80, 154) from its seated position. A mass in the form of a spherical ball (74, 160) functions to move the piston (66, 166) to dislodge the closure ball (80, 154). The mass (80, 154) rests on a conical ramp (56, 126) and the slope of the ramp serves to direct the mass (80, 154) against the piston (66, 166). A steep sloped ramp (126) may be used in combination with a piston (166) having a cylindrical center portion (168). Or, a shallow ramp (56) may be used in combination with a piston (66) having a flat upper surface and radial legs (68, 70) which fit within radial slots (58) in the ramp (56).
