摘要： An internal combustion engine having at least one and preferably two cylinders each with a reciprocating piston, and a compressor which has a reciprocating piston driven by the engine to compress a rich fuel and air mixture within the compressor to inject the mixture directly into the combustion chamber of each engine cylinder. The mixture is ignited by a spark plug to drive the pistons of the engine through their power strokes and rotate an associated crankshaft which is connected to a compressor crankshaft to reciprocate the piston within the compressor and thereby compress and then inject the fuel and air mixture into the engine cylinder. A carburetor preferably supplies an enriched fuel and air mixture to the compressor to reduce the complexity of the system. The fuel and air mixture is preferably substantially atomized through nozzles adjacent each cylinder to improve combustion of the mixture. Preferably the engine is a two-stroke engine with two cylinders and the compressor is driven at twice the speed of the engine.

摘要： A two-stage fuel pump for furnishing fuel to an internal combustion engine utilizes a side or lateral channel pump as a first stage pump to furnish liquid fuel to a second stage pump. A common armature drive shaft drives both pumps and central passages in the vicinity of the drive shaft receive vapor developed in the first stage pump and cause the vapor to exit the pump assembly. A conical baffle directs vapor free fuel to a periphery where it enters the inlet side of the second or main stage pump. A rotor in the first stage pump has central axial passages to facilitate the egress of vapor from the pump assembly.

摘要： A flat commutator for an electric motor of a vehicle fuel pump. The commutator is made with a one-piece carbon ring having a flat outer face, a one-piece conductor ring with a base portion embedded in the carbon ring and underlying outer face, and a housing of a plastic insulating material molded on the rear face of the carbon ring and adapted to mount the commutator on a motor armature. A plurality of circumferentially spaced apart grooves extend radially and axially completely through both the carbon ring and the conductor ring to provide a plurality of individual sintered carbon segments each with a separate conductor for electrically connecting the segments with armature coils.
