摘要： An accumulator for a no-return fuel system for a vehicle engine with fuel injectors. The accumulator has a housing with a flexible diaphragm between first and second chambers and a spring in one chamber yieldably closing the diaphragm to reduce the volume of the other chamber. One chamber has a fuel inlet that allows fuel into the chamber which accommodates expansion of the fuel by increasing the volume of the chamber against the bias of the spring. Preferably, the diaphragm has an over-pressure valve which opens when the system has reached its maximum over-pressure to allow the fuel to flow from one chamber to the other chamber in bypass relation to the injectors. The other chamber has an outlet communicating directly with the fuel tank. In another embodiment, the accumulator has a housing with a flexible diaphragm between first and second chambers in which one chamber has a fuel inlet for communication with the fuel rail and the other chamber continuously communicates with the engine air intake manifold so that the pressure drop across the engine fuel injectors is maintained more constant as the manifold pressure varies.

摘要： An apparatus to control the flow of hydrocarbon fuel vapor from a vehicle fuel tank. The apparatus is mounted adjacent the top of the fuel tank and contains a valve system which controls fuel vapor flow from the tank to a receiving canister and prevents the vapor from escaping to the atmosphere. The valve system utilizes a diaphragm, operably connected to a main valve, to prevent the vapor pressure in the fuel tank from closing the valve. The main valve is actuated by a float responsive to the level of fuel in the tank and remains open when the fuel level is below a designated level and closes due to a sufficiently high fuel level or in a vehicle roll-over condition to prevent liquid fuel from escaping from the fuel tank through the apparatus.

摘要： A damper in a self-contained electrically operated fuel pump for vehicle engines incorporating a positive displacement pumping element. The damper has a hollow toroidal flexible element in contact with the liquid fuel discharged from the pump for absorbing pulsations. A retainer with a locating plate on one side of the damper centers it in the pump housing and has resilient circumferentially spaced, radial fingers extending over and around the periphery of the toroid to confine it against destructive expansion while permitting limited expansion and contraction needed to absorb fuel pressure pulsations in pump operation.

摘要： A system for automotive vehicles carrying a fuel tank for volatile fuels which is directed to avoiding the escape to atmosphere of fuel vapors which rise from the liquid fuel. The system includes a collector dome on the fuel tank and a storage canister for vapors. A vapor pump is provided for reducing the stored vapor to liquid before directing it from a high pressure tank into the fuel supply leading to the engine of the vehicles. The vapor pump is powered by an electrical source or, alternatively, by the vehicle engine. A pressure responsive switch controls the initiation of the vapor pump action. A standard fuel pump in the fuel tank delivers liquid fuel to the fuel injection system of the engine.

摘要： A fuel delivery system for an internal combustion engine that includes a fuel supply with a pump responsive to application of electrical power for supplying fuel under pressure. A fuel injector is coupled to the supply for controlled delivery of fuel from the supply to the engine. A check valve is positioned in the fuel line that connects the pump outlet to the injector to prevent reverse flow of fuel from the injector to the pump when the pump is shut down. A sensor is coupled to the fuel line between the check valve and the pump outlet for providing an electrical signal as a function of fuel pressure at the pump outlet, and electronic control circuitry applies electrical power to the pump as a function of such pressure signal. A fuel bypass is connected to the fuel line between the pump outlet and the check valve for providing an open but restricted fuel flow path from the pump outlet parallel to the fuel line, such that fuel continues to flow through the bypass and the pump continues operation even in the absence of fuel demand at the engine. In this way, the pump maintains a minimum level of operation so as to be able rapidly to accommodate increasing demand for fuel at the engine.

摘要： An electric-motor fuel pump that includes an inlet end cap, an outlet end cap and a case coaxially joining the end caps to form a closed pump housing. An electric motor is disposed with the housing, and includes an armature journalled for rotation between the end caps, a stator surrounding the armature and means for applying electrical power to the motor. The armature is coupled to a gerotor mechanism for pumping fuel from the inlet to the outlet through the housing. The gerotor pumping mechanism comprises an annular wall on the inlet end cap forming an open pocket axially opposed to the armature. Inner and outer gear rotors are disposed within the pocket, and have radially opposed intermeshing teeth that define circumferentially disposed expanding and ensmalling pumping chambers. The inner gear rotor is coupled to the motor armature. Inlet and outlet gerotor ports in the inlet end cap axially open between the rotors into the expanding and ensmalling chambers respectively. A bearing pad is affixed to the inlet end cap well adjacent to the outlet port, and extends radially inwardly through a gap that separates the end cap wall from the outer gear rotor to an arcuate bearing surface in sliding contacted with the gear rotor. Preferably, the inlet end cap, wall and bearing pad are of one-piece integral construction.

摘要： A two-cycle engine has an air inlet in the crankcase, and a spiral air-fuel passage encircling the cylinder wall rising from the crankcase to an inlet in the cylinder head to effect cooling of the cylinder. A fuel injection device introduces fuel into the transfer passage. A unidirectional valve admits air and fuel into the cylinder head and curved fins impart a swirling action to the air and fuel to effect a fuel and air stratification. An exhaust passage in the cylinder wall has an adjustable throttle to control dirctly the outflow of exhaust gases and indirectly the inflow of fresh fuel-air mixture, whereby the power level of the engine is controlled.
