ABSTRACT:
A two cycle internal combustion engine is disclosed incorporating a spherical joint between the piston and the connecting rod. The spherical joint draws lubricating oil into a clearance volume, wherein the oil is sealed therein to hydrostatically transfer piston loads thereacross as the piston reciprocates. The engine further includes a working pump piston for operating on hydraulic fluid. An accumulator chamber is also provided in combination with the engine, wherein the pressure of the fluid in the accumulator chamber is maintained equal to the working fluid pressure of the engine pump by valve means. Also disclosed is a pulse pressure booster for delivering charged air to the combustion chamber of the engine. The pulse pressure booster receives pressurized sump gas and includes a piston for separating the inlet air from the sump gas while communicating pressures thereacross. Also disclosed is an improved reaction valve in the hydrocycle engine pump, wherein the valve incorporates a spring disk configuration to facilitate faster opening of the reaction valve.
