Abstract: A supercharged internal combustion engine has a supercharger operable to selectively supply a mass of air from below through above atmospheric air pressure according to the operating requirements of the engine. The supercharger has a shuttle combined with a throttle valve that controls the mass of air directed to an air mass bypass opening and supplied to the internal combustion engine. The shuttle has rollers that ride on rails that allow the shuttle to move to open and close the air mass bypass opening in communication with a casing that directs a mass of atmospheric air and a bypass mass of air interfused with the mass of atmospheric air to an air mass inlet of the supercharger.

Abstract: A diesel or diesel-like internal combustion engine drivably connected to a variable internal compression ratio supercharger that supplies varying amounts of air to the engine responsive to the load requirements of the engine. The supercharger has a pair of rotors concurrently driven by the engine to move air to the engine. A slide assembly associated with screw rotors is movable with a controller relative to the rotors to bypass air to atmosphere and regulate the amount of air and pressure of the air compressed by the screw rotors to the engine to increase the engine's efficiency.

Abstract: An internal combustion engine is coupled to a supercharger operable to supply varying amounts of air to the engine responsive to the load on the engine. The supercharger has a pair of screw rotors driven by the engine to move air to the engine and a control apparatus for varying the mass and pressure of air supplied to the engine.

Abstract: A pump has an extruded metal housing surrounding a square internal chamber accommodating a piston assembly with square pistons. An eccentric member and block assembly associated with a driven shaft reciprocates the piston assembly to pump fluid. The flow of fluid into and out of the pumping chamber is controlled with intake and exhaust valves incorporated into plates mounted on opposite ends of the housing.

Abstract: An internal combustion engine has rotary valves associated with movable shutters operable to vary the closing of intake air/fuel port sections to obtain peak volumetric efficiency over the entire range of speed of the engine. The shutters are moved automatically by a control mechanism that is responsive to the RPM of the engine. A foot-operated lever associated with the control mechanism is also used to move the shutters between their open and closed positions.

Abstract: A seal assembly slidably mounted in a slot in the piston engages the cylindrical internal wall of the housing to form separate chambers. The housing has arcuate slots non-concentric with its cylindrical internal wall accommodating rollers connected to the seal assembly to maintain the seal assembly in constant and substantially uniform sealing engagement with the internal wall of the housing.

Abstract: An internal combustion engine having a head with valve assemblies for controlling flow of intake and exhaust gases to and from piston chambers. A head plate is located between the head and a block having cylinders accommodating pistons. The head plate has openings in communication with the cylinders and valve assemblies. Each valve assembly has a continuous ceramic sleeve having an intake port, and an exhaust port. Rotatably disposed within the sleeve is a rotatable valve body having a valving combustion chamber open to a piston chamber. A spark plug is mounted on each valve body. A first pressure responsive seal mounted on the valving body has a sealing surface engageable with the sleeve. A second pressure responsive face seal is located between the head plate and the rotating valve body. The valving body and first seal are rotatably driven to sequentially align the valving combustion chamber with the intake port and exhaust port during the operation of the engine.

A ceramic segment seal member movably mounted on the valving body has sealing surfaces engageable with the sleeve. A face seal is located between the head plate and the rotating valve body. The valving body and seal member are rotatably driven to sequentially align the valving combustion chamber with the intake port, ignition hole, and exhaust port during the operation of the engine.

Abstract: A rotary internal combustion engine has a housing with an elliptical inside surface surrounding an elliptical rotor forming with the housing combustion chambers. Valve and ignition assemblies connected to a source of air under pressure and injectors for introducing fuel into the air supply sequentially allows the air and fuel mixture to flow into the combustion chambers and ignite the air and fuel mixture therein. Vane and seal assemblies on the rotor and housing are controlled with cam and linkages to provide positive effective gas seals between the housing and rotor. A slack adjuster maintains lateral sealing relationships between the housing vane and seal assemblies and opposite side walls of the housing.

Abstract: An air pump and compressor having a housing with a cylindrical internal chamber. A plurality of pairs of intake and exhaust valves mounted on the housing control the flow of air into and out of the chamber. A piston located within the chamber is mounted on a shaft rotated on the housing. The shaft has a primary eccentric that supports the piston in the chamber. A pair of secondary eccentrics spaced from the primary eccentric are mounted on the piston and housing to control the orbital movement of the piston. Seal assemblies slidably mounted in slots in the piston engage the inner cylindrical wall of the housing to form separate pumping chambers. Each pumping chamber is in communication with an intake valve and an exhaust valve so that on orbital movement of the piston the air flows into and is pumped out of each pumping chamber.
