Abstract
A two-stroke internal combustion engine which comprises two rocking pistons disposed on opposite sides of a separating element that separates two pump chambers from each other. The pump chambers are located on the back side of the rocking pistons, and a hollow rotary slide is mounted in the separating element to positively control the intake and precompression phases of the pump chambers.
Claims7
A two-chamber, two-stroke rocking piston internal combustion engine comprising:
- a. a housing having a cavity therein;
- b. two rocking pistons directly mounted on a common shaft in said housing cavity, each of said rocking pistons having a forward side delimiting a work chamber and a back side delimiting a pump chamber, each of said pistons being movable through a work stroke and a compression stroke, precompression of fresh air taking place in said pump chamber as each piston moves through its work stroke;
- c. a hollow, cylindrical, stationary separation element located between the two pump chambers, said separation element having control slots therein;
- d. a hollow, rotatable slide mounted in said separation element and having an internal fresh air intake channel and a through flow slot for cooperation with said control slots in the separation element to positively control admission of fresh air into the two pump chambers and also positively control precompression thereof in said two pump chambers;
- e. by-pass channels formed in said housing and extending between each pump chamber and the associated work chamber;
- f. means connecting each by-pass channel for communication with one pump chamber and the associated work chamber so as to permit scavenging and recharging of such work chamber by precompressed fresh air from the pump chamber when the piston delimiting such chambers reaches a position wherein there is fluid flow communication between such pump chamber and the work chamber;
- g. means, coupled with the engine, for supplying fuel thereto;
- and
- h. ignition means associated with each work chamber.
