摘要： PROBLEM TO BE SOLVED: To provide a vaporized fuel leakage inspection system capable of reducing amount of electric power consumption and being light in weight.
SOLUTION: A diaphragm 22 of a differential pressure regulating valve 20 is displaced due to difference in pressure between a canister port 24 and a pressure chamber 26 and shuts off and continues communication between the canister port 24 and an atmospheric air port 25. A first suction and exhaust port 31 of a pump 30 is communicated with the canister port 24 through a filter 16, and a second suction and exhaust port 32 is communicated with the pressure chamber 26. The second suction and exhaust port 32 of the pump 30 is communicated with a pressure detection passage 202 between a differential pressure sensor 14 and a reference orifice 210 through a check valve 50. The check valve 50 inhibits air flow from the second suction and exhaust port 32 to a reference orifice 210 side. By inverting the direction of rotation of a motor 34, suction and exhaust are switched between the first suction and exhaust port 31 and the second suction and exhaust port 32.

摘要： PROBLEM TO BE SOLVED: To reduce fluctuation in the lift timing of a second valve member in a solenoid valve with two-stage valve members. SOLUTION: A first connecting pipe 14 of the solenoid valve 10 is connected to a fuel tank side, and a second connecting pipe 16 to a canister side. A spring 28 urges a movable core 30 and a first valve member 50 toward opening the solenoid valve 10. A shaft 52 of the first valve member 50 has a flow control part 54 at the distal end of a pressure receiving member 71 side. The flow control part 54, formed into a taper in the direction of insertion, is inserted in a communication passage 72, with an abutting part 62 of a bellows 60 seated on a projected part 76a of a rubber member 76. The communication passage 72 in the pressure receiving member 71 is formed into a taper in the direction of inserting the flow control part 54. Upon energization of a coil 40, the first valve member 50 moves in the direction of driving the flow control part 54 out of the communication passage 72. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a pump device reduced in rotating loss by preventing a frictional force from being increased by a seal.
SOLUTION: A vane pump comprises a pressure plate 17 disposed between a rotor 1 and a second side housing 6, a biasing means 18 biasing the pressure plate 17 to the rotor 1 side, and a pressurized fluid imparting means 20 guiding a discharge air into a cancel chamber 19 formed between the pressure plate 17 and the second side housing 6. The force in the side outer direction is generated in the pressure plate 17. The force in the side inner direction is generated in the pressure plate 17 by the high-pressure discharge pressure guided into the cancel chamber 19. Namely, the force in the side outer direction is canceled by the force in the side inner direction. By the cancel mechanism, the sealing performance can be secured even if a seal member is not strongly pressed against the rotor, and the rotating loss of the rotor 1 can be reduced.
