IC engine with rectilinear piston motion - has two sets of pistons which move in opposite directions, with valves operated by incompressible fluid

摘要

The engine, designed to convert the energy of an explosive mixture into the compression of a gas or fluid, has no rotary components. Its distribution valves (A1-E3) are controlled by an incompressible fluid which moves, with the engine operating phases, in one direction, from piston to piston, with the pistons returning to their original positions by a return movement of an incompressible fluid. In a variant of the design the return movement of the pistons can be provided by having a series of eight pistons in opposite pairs, all linked mechanically to a single pressure piston in a master cylinder. ADVANTAGE - Reduced weight and pollution, obviating need to convert reciprocating motion to rotary and back for propulsion, e.g. of vehicle, boat or aircraft.
