摘要:
A coupler for connecting the confronting ends of two fluid lines. The coupler includes a coupler housing having a generally tubular body extending along a longitudinal axis. The body includes an opening at a first end thereof for receiving a first tube in the body and an opening at a second end thereof for receiving a second tube in the body. Seals are provided for sealing engaging an end portion of the first tube within the body and for sealingly engaging an end portion of the second tube within the body. A clip extends radially inwardly from a slot in the body for engaging the first tube to retain the first tube within the body and to limit the longitudinal movement of the first tube into the body. The body includes a frangible neck portion intermediate the openings at the ends of the body for separating the first and second tubes by shearing the body at its neck portion.

A layered tubing for use in a motor vehicle has five layers, namely a thick tubular outer layer formed of a Nylon 11 or Nylon 12, a thick tubular intermediate layer of Nylon 6, a thin tubular intermediate bonding layer between and bonded to the thick outer and intermediate layers and formed of polyethylene or polypropylene, a thin tubular intermediate solvent-blocking layer inside the thick layers and formed of a copolymer of ethylene and vinylalcohol, and an inner layer of Nylon 6 inside the blocking layer. The thick outer and intermediate layers each have a thickness of between 0.2 mm and 0.7 mm. The thin intermediate blocking layer comprises by weight 30% to 45% polyethylene and the intermediate blocking layer has a thickness of between 0.1 mm and 0.2 mm. The inner layer has a thickness of at most 0.1 to 0.5 mm and the bonding layer has active side chains of maleic acid anhydride and a thickness of between 0.05 mm and 0.2 mm.
摘要:
A pulsation preventive member for use with a pump constructed in the form of a hose disposed in a pump fluid passage. The hose is located in a fuel tank in such a manner that one end of the hose is connected with the pump and the other end of the hose is connected with a injector or the like. The hose is constructed so as to substantially inhibit pulsation by elastically deforming. The hose may have a substantially circular cross-sectional shape and a mesh-shaped thread layer incorporated therein. The mesh angle of the thread layer is preferably less than 50 degrees. Alternatively, the hose may have non-circular cross-sectional shape such as rectangular or elliptical cross-sectional shape. Further, the hose may be constructed so as to have a double-walled structure comprising an inner layer and an outer layer in the form of a hose with a plurality of connecting members interposed therebetween.

A marine propulsion system includes a two cycle water cooled crankcase compression internal combustion engine (52) including a vapor separator (33), a remote fuel tank (60), and a fuel pump (62) in the tank for delivering fuel to the engine in response to crankcase pulse pressure. A combination conduit (64) between the fuel tank and the engine includes a first passage (66) communicating crankcase pulse pressure from the engine to the fuel pump in the tank, a second passage (70) supplying fuel from the pump in the tank to the engine, a third passage (74) returing fuel vapor from the vapor separator at the engine back to the tank, a fourth passage (78) supplying cooling water from the engine towards the tank, and a fifth passage (82) returning water from the fourth passage back to the engine.
摘要:
An automatic shut off device for preventing air from entering the fuel system of an internal combustion engine when the fuel supply becomes low. The device provides a fuel chamber having an inlet connected to a fuel supply line, a float switch and an outlet connected to the engine fuel pump or fuel system. When the fuel supply falls below a preselected low level, but before the level reaches a lower inlet to a standpipe, the float switch is actuated to shut down the engine before air can enter the engine fuel system, thereby eliminating the necessity of bleeding the fuel system when the fuel supply is restored. A bleed orifice at the top of the fuel chamber allows trapped air to escape and return to the fuel tank when fuel is restored to the device.

An alternative fuel management system may include a base configured for arrangement on a supporting floor or other framework of a vessel and configured to support alternative fuel supply equipment. The system may also include a sealed enclosure sealingly coupled to the base and configured to surround the alternative fuel supply equipment. The system may also include the alternative fuel supply equipment and it may be arranged within the sealed enclosure. The alternative fuel supply equipment may include a high-pressure pump, a fuel filter, a transfer pump, and a high-pressure fuel delivery line extending across the sealed enclosure and configured to provide alternative fuel from the high-pressure pump to a combustion engine. The alternative fuel management system may also include a purge fluid system configured to deliver purge fluid to the combustion engine from a source of purge fluid.

A protective structure includes: a base including a base main wall attached to a vehicle body wall defining a part of an engine room and extends vertically, a stay fixed to the base main wall to hold a fuel line, and a base extension wall extending from an upper part of the base main wall in a direction away from the vehicle body wall; a cover including a cover main wall disposed to oppose the base main wall and to be located in front of the stay and the fuel line, a cover extension wall extending from the cover main wall along the base extension wall, and a leg extending from the cover main wall toward the base main wall below the cover extension wall; and a fastening member extending vertically through overlapping parts of the base extension wall and the cover extension wall to fasten the base and cover.
摘要:
A flexible hose or a tubing having a barrier layer of polyamide 6 having an impact modifier, and/or branched molecular structure, a flexural modulus of 1 to 2 GPa and/or a tensile elongation of 100% or more. The hose may have additional layers such as an HNBR rubber inner tube, an EVM/CPE rubber blend outer cover, a textile or wire reinforcement, or the like. Permeability to ethanol- and methanol-containing fuels is very low. Permeability to B20 biofuels is very low.
