High efficiency explosion engine with a double acting piston
First Claim
Patent Images
1. A high-efficiency engine having a double-acting central piston cooperating with auxilliary feed and inlet units, the engine comprising:
- a cylinder having a central axis and in which a piston slides and on said central axis a through-shaft is fixed, said shaft being subdivided by the piston into two coaxial half-shafts having outer ends provided with auxilliary pistons slidably positioned within inlet chambers, and exhaust openings provided in the central part of the cylinder;
at least one of the two free ends of the half-shafts being connected to a connecting rod;
said inlet chambers being provided with non-return valves for permitting gases to be fed into the inlet chambers; and
at least one pair of gas intake valves oriented with one valve through each end of the cylinder on opposite sides of the piston, the gas intake valves being controlled by the auxilliary pistons for permitting gases to be cyclically fed from the inlet chambers to the cylinder.

Abstract
A high-efficiency explosion engine has a double-acting central piston mounted on a shaft within a cylinder to form two combustion chambers. Auxilliary pistons mounted on the ends of the shaft control the intake of gases to the combustion chambers. In one embodiment, the auxilliary pistons are mounted axially offset from the piston shaft. In a further embodiment, fuel is provided through the piston shaft into the combustion chambers dependant upon the position of the piston within the cylinder.
