Abstract: An internal combustion engine is disclosed, having at least one combustion chamber disposed in an engine casing. At least one fuel injector is mounted to the engine casing for supplying fuel to the at least one combustion chamber. The at least one fuel injector has at least one fuel supply inlet. A fuel supply assembly is mounted to the at least one fuel injector. The assembly is mounted adjacent to the at least one fuel injector for supplying the fuel to the fuel injector. The assembly has at least one fuel supply outlet. The assembly is mounted to the at least one fuel injector by a cooperative fit, such that the at least one fuel supply inlet and the at least one fuel supply outlet align in a sealed relationship to allow fluid communication therebetween. A method of assembling an engine is also disclosed.

Abstract: A pump is disclosed, having a pumping chamber in the rotor. The rotor is rotatable between first, second, third and fourth positions. When the rotor is in the first position, an inlet cam assembly displaces a piston to draw fluid into the pumping chamber via a first housing inlet. When the rotor is in the second position, an outlet cam assembly displaces the piston to expel fluid out of the pumping chamber via a first housing outlet. When the rotor is in the third position, the inlet cam lobe assembly displaces the piston to draw fluid into the pumping chamber via a second housing inlet. When the rotor is in the fourth position, the outlet cam assembly displaces the piston to expel fluid out of the pumping chamber via a second housing outlet. A method of pumping fluid is also disclosed.

Abstract: A solenoid actuated fuel injector for liquified petroleum gas (LPG), compressed natural gas (CNG) or the like has a fuel passage therethrough and a valve to control the flow of fuel through the fuel passage. The valve has a valve head formed of a generally flexible and substantially resilient material engageable with a valve seat to prevent fuel flow through the injector. The valve is preferably spring biased to a closed position which compresses the valve head against the valve seat to prevent fuel flow between them. Compression of the valve head is preferably limited by contact between the metal valve body and the metal valve seat which limits the travel of the valve body relative to the valve seat. The valve head and valve seat are also constructed to be highly resistant to wear to provide a consistent seal between them.
