20100243353 | ARRANGEMENT OF CANISTER IN SADDLE-RIDING TYPE VEHICLE - A canister is provided which efficiently purges in a saddle-riding type vehicle having an engine disposed downwardly of a rider seat so as to develop a drive power for driving a rear wheel, a fuel tank storing fuel to be supplied to the engine, and a canister adsorbing fuel vapors generated in the fuel tank. An air guide path that guides exhaust air discharged rearwardly from a radiator, which circulates coolant with an engine, is formed inside a vehicle body cover. The canister is disposed in the air guide path. | 09-30-2010 |
20110011373 | FUEL SUPPLY DEVICE - An inexpensive fuel supply device having a high output is achieved using low-output fuel pumps. | 01-20-2011 |
20120234302 | EVAPORATIVE FUEL TREATMENT APPARATUS OF VEHICLE - An evaporative fuel treatment apparatus for a vehicle is provided with a reverse flow preventing valve provided in a fuel supply pipe, a positioning plate provided on the fuel supply pipe, a pressing plate mounted slidably on the fuel supply pipe between the positioning plate the reverse flow preventing valve, a seal member clamped between the positioning plate and the pressing plate, and a stopper. When the fuel supply is started, the reverse flow preventing valve is configured to be set opened so as to form a liquid trap between the reverse flow preventing valve and the pressing plate. When the liquid surface reaches the pressing plate, the fuel pushes the pressing plate upward and the seal member is collapsed in the vertical direction so that the seal member protrudes toward the fuel supply gun insertion holes and makes tight contact with the fuel supply gun to seal a gap. | 09-20-2012 |
20120240904 | EVAPORATED FUEL TREATMENT DEVICE FOR VEHICLE - An evaporated fuel treatment device for a vehicle is provided to suppress the flowout of evaporated fuel into atmospheric air. In the evaporated fuel treatment device, a communication chamber is formed in a fuel supply cap, allowing communication between a charge passage and the inside of a fuel tank in a closed state. In the communication chamber, a positive pressure adjusting valve is openable to supply evaporated fuel in the fuel tank to an evaporated fuel storage unit through the communication chamber and the charge passage, and a negative pressure adjusting valve is openable to supply atmospheric air to the fuel tank from the evaporated fuel storage unit through the communication chamber and the charge passage. An interlocking member is provided between the key cover and the negative pressure adjusting valve, and opens the negative pressure adjusting valve in an interlocking manner with an operation of opening the key cover. | 09-27-2012 |
20120240906 | EVAPORATED FUEL TREATMENT DEVICE FOR VEHICLE - An evaporated fuel treatment device is provided to treat evaporated fuel by using a fuel supply cap with a small size while the flowout of fuel can also be suitably prevented. The evaporated fuel treatment device includes a positive pressure adjusting valve which opens when an inner pressure of a fuel tank becomes a predetermined pressure or more, and a spherical rollover valve which closes the positive pressure adjusting valve when the fuel tank is inclined at an angle equal to or larger than a predetermined angle. The positive pressure adjusting valve and the spherical rollover valve are mounted on one cylindrical portion formed on a fuel supply cap. | 09-27-2012 |
20120247434 | EVAPORATIVE FUEL TREATMENT APPARATUS FOR VEHICLE - An evaporative fuel treatment apparatus for a vehicle includes a direct purge channel for supplying evaporative fuel to a purge channel without involving a canister; a purge control valve for controlling communications between the canister and an air-intake system of an internal combustion engine by an opening and closing operation; a direct purge control valve for controlling communications between a fuel tank and the air-intake system by another opening and closing operation; and a two-way valve provided in a charge channel. During a purge mode of the apparatus, evaporative fuel adsorbed in the canister is purged to the air-intake system by closing the direct purge control valve and opening the purge control valve during operation of engine. During a direct purge mode of the apparatus, evaporative fuel in the fuel tank is purged to the air-intake system by closing the purge control valve and opening the direct purge control valve. | 10-04-2012 |
20120255525 | EVAPORATED FUEL HANDLING APPARATUS - A fuel cap includes a communication chamber configured to make a charge path and the inside of the fuel tank communicate with each other while in a closed state. The communication chamber includes: a positive pressure control valve configured to open, and send evaporated fuel, which occurs inside the fuel tank, to an evaporated fuel reservoir via the communication chamber and the charge path when the internal pressure of the fuel tank becomes equal to or greater than a predetermined pressure; and a negative pressure control valve configured to open, and send air from the evaporated fuel reservoir to the fuel tank via the communication chamber and the charge path when the internal pressure of the fuel tank becomes equal to or less than the predetermined pressure. In addition, a key cylinder sets the negative pressure control valve open upon inserting a key into the key cylinder. | 10-11-2012 |
20130014730 | VAPORIZED FUEL TREATMENT APPARATUS FOR VEHICLEAANM SHIMURA; TakeshiAACI Wako-shiAACO JPAAGP SHIMURA; Takeshi Wako-shi JPAANM IMAMURA; TakahiroAACI Wako-shiAACO JPAAGP IMAMURA; Takahiro Wako-shi JP - A vaporized fuel treatment apparatus for a vehicle including a fuel tank for storing fuel therein with an openable and closable gas filler cap attached to the fuel tank. A vaporized fuel storage is operatively connected to a charge path through which the fuel tank communicates with the vaporized fuel storage and a purge path through which the vaporized fuel storage communicates with an intake system of an internal-combustion engine. A lid covers the gas filler cap to be opened and closed and is supported on a vehicle body. The vaporized fuel treatment apparatus is provided with a positive-pressure adjustment valve for opening when the internal pressure of the fuel tank reaches a predetermined pressure, allowing the fuel tank to communicate with the vaporized fuel storage. The positive-pressure adjustment valve opens when the lid is opened. | 01-17-2013 |
20130153319 | SADDLE-RIDE TYPE VEHICLE - To enable the effective supply of fuel in a low remaining fuel condition, even in a saddle-ride vehicle with a requirement for an increased fuel tank capacity being provided within a limited amount of space. The saddle-ride vehicle includes an engine having a cylinder disposed on a crankcase; an intake system component disposed at the rear of the cylinder for sucking air into the engine; and a fuel tank disposed above the engine for storing fuel. The saddle-ride type vehicle includes a fuel suction port in a side bottom plate portion of the fuel tank for feeding fuel to the intake system component. The saddle-ride vehicle has a sub-chamber having a wall that surrounds the fuel suction port and the sub-chamber includes a fuel flow opening toward the vehicle rear. | 06-20-2013 |
20150041466 | FUEL CAP PROVIDED WITH BREATHER MECHANISM - In a fuel cap provided with a breather mechanism, a cap openably and closably covers a fuel filler of a fuel tank. The cap includes a breather passage for communication between the inside and the outside of the fuel tank. The breather passage is provided with a breather valve mechanism and a resonator chamber as a silencing mechanism. The breather mechanism is a valve having a spring capable of retaining a pressure within the fuel tank up to a predetermined pressure. | 02-12-2015 |
