Abstract
The two-cycle engine is constructed with a flywheel having pockets spaced about the periphery. The flywheel receives charges of combusted media at spaced apart points so as to rotate the flywheel. Each piston/cylinder arrangement for delivering power to the flywheel cooperates with a spring-biased counter-piston whereby after ignition, the counter-piston moves away from an associated piston to permit exhausting of the combusted mixture into a pocket of the rotating flywheel. The spring stores the energy caused by combustion and delivers the energy into the flywheel during exhaustion of the combusted mixture.
Claims20
In a two-cycle engine, the combination comprising
- a rotatably mounted flywheel having at least one transfer pocket therein;
- a stationary housing means having at least one radially disposed cylinder therein for receiving a combustible mixture, a chamber opposite said cylinder and a power transmission cavity communicating with said chamber and facing said flywheel;
- a piston slidably mounted in said cylinder;
- transmission means for reciprocating said piston in said cylinder to compress a combustible mixture therein;
- ignition means for igniting a compressed combustible mixture in said cylinder;
- a counter-piston slidably disposed in said chamber of said housing means opposite said cylinder and piston to move from an extended position adjacent said cylinder to a retracted position spaced from said piston and said cylinder under the force of an ignited combustible mixture in said cylinder;
- and
- a spring biasing said counter piston from said retracted position to said extended position to exhaust a flow of the combusted mixture from said chamber through said power transmission cavity into said pocket of said flywheel to effect rotation of said flywheel.
A two-cycle engine comprising
- a stationary main housing having a plurality of peripherally disposed cylinders disposed radially of a common central axis and a plurality of chambers, each chamber being disposed opposite a respective cylinder;
- a plurality of pistons, each piston being slidably disposed in a respective cylinder;
- transmission means for reciprocating each piston within a respective cylinder sequentially from an intake position, through a compression position, to an ignition position;
- a plurality of secondary housings spaced about said main housing, each secondary housing having a chamber therein in facing relation to a respective cylinder of said main housing;
- a plurality of counter-pistons, each counter-piston being slidably disposed in a respective chamber in a respective secondary housing opposite said piston in a respective cylinder;
- a plurality of springs, each spring being disposed between a respective counter-piston and said secondary housing to bias said respective counter-piston towards a respective cylinder;
- a power transfer cavity in each said secondary housing disposed in communication with a respective chamber to receive an exhaust flow therefrom;
- a flywheel rotatably mounted on said axis of said main housing, said flywheel having a plurality of transfer pockets disposed therein for sequentially receiving an exhaust flow from a series of said power transfer cavities;
- intake means for directing a combustible mixture into each respective cylinder prior to a respective piston in said cylinder reaching said compression position;
- and
- means for igniting a combustible mixture in each respective cylinder at said ignition position of a piston therein to effect a flow of combusted mixture into a respective oppositely disposed chamber.
