20080245513 | Tube for heat exchanger and method of manufacturing tube - A tube for a heat exchanger is constructed of a single plate having one end portion and the other end portion in a width direction perpendicular to a tube longitudinal direction. The single plate having opposite first and second wall surfaces is bent to have a protruding portion at a position adjacent to the one end portion in the width direction and a contact portion adjacent to the protruding portion in the width direction. The protruding portion is configured to continuously extend in the longitudinal direction and to have a protruding tip on a side of the first wall surface, and the protruding tip contacts the first wall surface of a portion along the longitudinal direction. The second wall surface at the one end portion and the contact portion contacts the first wall surface at the other end portion and a position near the other end portion, respectively. | 10-09-2008 |

20110123372 | VANE PUMP AND EVAPORATIVE LEAK CHECK SYSTEM HAVING THE SAME - An upper casing and a lower casing cooperate together to define a pump chamber, in which a rotor is rotatably received. A surface of the lower casing, which is opposed to one end surface of the rotor in an axial direction of the rotor, has a recess that is recessed for a predetermined amount away from the rotor in the axial direction of the rotor. A surface of a plate portion of the upper casing, which is opposed to the other end surface of the rotor in the axial direction of the rotor, has a recess that is recessed for a predetermined amount away from the rotor in the axial direction of the rotor. An outer peripheral edge of each of the recesses is placed radially inward of an outer peripheral edge of the rotor in an axial view of the rotor. | 05-26-2011 |
20110138885 | VANE PUMP AND EVAPORATION LEAK CHECK SYSTEM USING THE SAME - A vane pump has an upper casing, a lower casing, a rotor and a motor. First to fourth points are defined on an outer peripheral end of a lower flat surface of the lower casing. The first point is farthest from an intersection between an axis of a shaft of the motor and the lower flat surface. A suction passage passing through the third point and a discharge passage passing through the second point are formed between the upper casing and the lower casing. The fourth point is defined in a range from the third point to the first point. The lower flat surface is provided to incline with respect to the axis of the shaft of the motor such that the fourth point is farthest from a motor case of the motor among points on the outer peripheral end. | 06-16-2011 |
20110311385 | Vane Pump and Vapor Leakage Check System Having the Same - A vane pump includes a housing defining a pump chamber; a rotor rotatably arranged in the pump chamber; and a motor to rotate the rotor. An imaginary plane is defined to bisect the pump chamber in an axis direction. The housing has a first inlet port and a second inlet port located symmetrical with each other with respect to the imaginary plane, and the housing has a first outlet port and a second outlet port located symmetrical with each other with respect to the imaginary plane. | 12-22-2011 |

20130014563 | EVAPORATED FUEL LEAK DETECTING APPARATUSAANM Itoh; TomohiroAACI Nagoya-cityAACO JPAAGP Itoh; Tomohiro Nagoya-city JPAANM Kobayashi; MitsuyukiAACI Gamagori-cityAACO JPAAGP Kobayashi; Mitsuyuki Gamagori-city JPAANM Sugihara; ShinjiAACI Mizuho-cityAACO JPAAGP Sugihara; Shinji Mizuho-city JP - A first determiner determines whether a pressure in a fuel tank is within a predetermined range when an ignition switch of an engine is on. A second determiner determines whether a valve allows or prohibits a communication between the fuel tank and a switch valve, when the first determiner determines that the pressure in the fuel tank is within the predetermined range. A control unit controls a pressure controlling portion based on a determination result of the first determiner and a determination result of the second determiner. A leak determiner determines whether the fuel tank has a leak of evaporated fuel based on a signal output from a first detector detecting a pressure in a detection passage and a signal output from a second detector detecting a pressure in the fuel tank. | 01-17-2013 |

20140026867 | FUEL VAPOR PURGE DEVICE - A fuel vapor purge device includes a canister connected to an internal combustion engine and a fuel tank via a purge passage to adsorb and hold a part of fuel vapor, a switch valve connected to the canister and to an atmosphere, and a pump connected to the switch valve via a pump passage and to the atmosphere via an atmosphere passage. The pump is capable of depressurizing or pressurizing an interior of the fuel tank, and the switch valve switches connection of the canister between with the atmosphere and with the pump. The fuel vapor purge device further includes a seal valve provided in the pump passage to open or close the pump passage depending on a pressure in the atmosphere passage. | 01-30-2014 |
20140060498 | FUEL VAPOR TREATMENT SYSTEM - An ECU controls a selector valve so as to connect a first pump passage and a second pump passage, and determines whether a fuel vapor leak from a fuel tank is in an allowable range based on a pressure in the fuel tank which is detected by a pressure sensor while a pump is driven to decrease a pressure in the fuel tank. The ECU opens a purge valve, whereby the fuel vapor adsorbed by a canister is introduce into an engine through an intake passage. The ECU controls the selector valve to connect a first pump passage and the second pump passage so as to circulate an atmospheric air in the pump while the purge valve is opened to introduce the fuel vapor into the internal combustion engine, whereby a foreign matter in the pump can be removed. | 03-06-2014 |
