摘要： An accumulator and over-pressure relief valve unit disposed within a vehicle fuel tank to accommodate expansion of fuel due to heating of the fuel within the fuel system and to maintain increased pressure of heated fuel in the fuel system to prevent vapor formation and to provide an over-pressure relief to bleed fuel back into the fuel tank when the unit has reached its maximum fuel accumulating capacity. The accumulator has a plastic cap press fit onto a plastic body with a diaphragm received therebetween and defining an expansion chamber with the body. To provide a seal between the cap and body, they are preferably ultrasonically welded together. The diaphragm has a normally closed valve which, when opened, communicates the accumulator chamber with the fuel tank. This valve opens in response to any over-pressure that may develop after the accumulator has reached its maximum accumulating capacity to bypass fuel into the fuel tank and thereby limit the maximum pressure of the fuel in the fuel system.

摘要： A valve in a fuel pressure regulator prevents liquid fuel from being emitted exteriorly of the regulator housing and onto heated engine components. In the preferred embodiment, the valve allows gaseous flow into a chamber of the regulator when the pressure within the chamber is lower than the pressure of gases exterior of the regulator but prevents gaseous flow from within the chamber to the exterior of the housing. In other embodiment an air-bleed passage is provided in the valve to allow gaseous flow from within the chamber to the exterior of the regulator.

摘要： A gear rotor fuel pump having a gear rotor pump assembly received on a cantilever bearing in an end cap of the pump and an armature journalled for rotation at one end in the bearing while being rotatably unsupported at its other end for preventing bearing misalignment and reducing pump noise. The end cap preferably carries a bellows modulator for reducing pump noise by reducing the amplitude of fuel pressure pulses transmitted to the bellows from the pump assembly through a port in the end cap. To further reduce noise, the end cap preferably has at least one cavity for receiving compressible gas therein to further absorb the pressure pulses as well as noise generated by turbulent fuel flow at a pump inlet. Preferably, the end cap has an interior locator surface which abuts the pump assembly and a locator groove which are both preferably machined relative to the bearing axis so that the pump assembly and armature are accurately axially and radially located in the pump to reduce pump noise while increasing performance, reliability, accuracy and repeatability in the mass production of the pump.

摘要： A two-stroke internal combustion engine having at least one cylinder with a combustion chamber defined between the cylinder head and a reciprocating piston, and a carburetor which delivers a rich fuel and air mixture to a compressor with a reciprocating piston driven by the engine to compress the mixture until the mixture is under sufficient pressure to open a differential pressure injection valve and thereby inject the mixture directly into the engine combustion chamber. The mixture is ignited by a spark plug to drive the engine piston through its power stroke and rotate its associated crankshaft which is connected to a crankshaft of the compressor to reciprocate its piston and thereby compress the fuel and air mixture and inject it into the cylinder in timed relation with the engine piston.

摘要： An electric-motor fuel pump that includes a housing with a fuel inlet and a fuel outlet, and an electric motor with a rotor responsive to application of electrical power for rotating within the housing. A pump mechanism includes an impeller coupled to the rotor for corotation with the rotor and having a periphery with a circumferential array of impeller vanes. A pair of plates oppose the sides of the impeller and a split ring surrounds the periphery of the impeller to form an arcuate pumping channel around the periphery of the impeller. Inlet and outlet ports at opposed ends of the pumping channel are operatively coupled to the inlet and outlet in the pump housing. Channels extend radially inwardly from the pockets in each side face of the impeller, and are interconnected by through-passages that extend through the impeller. A vapor vent is disposed in one of the side plates for sequential registry with the impeller through-openings for venting vapor from the pumping channel.

摘要： In a fuel system for an internal combustion engine powering a motor vehicle, a fuel reservoir canister mounted in a main fuel tank. An annular fuel filter element is enclosed in an axially elongate housing with radially spaced apart inner and outer cylindrical side walls. The housing is received in the canister with its outer side wall bearing on and radially supported by a complementary side wall of the canister. Preferably, a fuel pump and pressure regulator are disposed in the canister preferably so they overlap with and are encircled by the filter housing. The high pressure outlet of the fuel pump is connected to the filter to supply filtered fuel to the engine at a pressure regulated and controlled by the pressure regulator.

摘要： A fuel pressure regulator for a no-return fuel system for an automotive engine with fuel injectors having a housing with a flexible diaphragm between first and second chambers. The second chamber has a fuel inlet with a valve therein to admit fuel to the second chamber and an outlet to supply fuel to the engine. The second chamber is in continuous communication with the engine to accumulate any fuel expansion that may occur during engine deceleration or when the engine is turned off due to heating the fuel. The first chamber continuously communicates with the engine air intake manifold so that fuel is supplied to the engine fuel injectors at a substantially constant pressure drop across the injectors.

摘要： A main fuel tank in an automotive vehicle contains a reservoir in which is located a two-stage electrically operated pump. The first stage is a jet pump which draws fuel from the main tank and delivers it to the reservoir. The second stage is a rotary pump which draws from the reservoir and delivers to the vehicle engine. The reservoir has overflow restriction means which allows air to vent while the reservoir is filling but which restricts fuel flow when the reservoir is full. This creates pressure in the reservoir to create back pressure against and shut down flow from the jet pump and also increase pressure on the fuel inlet of the main pump thus increasing the efficiency of the main fuel pump.

摘要： A fuel pressure regulator with a flexible diaphragm defining in part first and second chambers in a housing and moving a ball valve in the first chamber to open and closed positions to regulate pressure of fuel discharged from the first chamber through an outlet having a seat on which the ball is received when the valve is closed. A cage carried by the diaphragm cooperates with a carrier member or disc fixed to the ball to provide a lost motion coupling between the diaphragm and the ball valve. This coupling permits movement within predetermined limits of the diaphragm generally axially, radially and pivotally relative to the ball while it remains on its seat and upon further generally axial movement of the diaphragm open and partially closes the ball valve to regulate and maintain substantially constant the pressure of fuel discharged from the chamber over substantially the full range of the rate at which the fuel is discharged. Preferably, to further improve regulation, a restricted orifice is disposed in the outlet downstream of the valve seat.
