High-efficiency explosion engine provided with a double-acting piston cooperating with auxiliary feed inlet units
First Claim
1. High-efficiency engine provided with a double-acting piston cooperating with auxiliary feed and inlet units, the engine comprising:
- a cylinder (2) having a central axis a piston (3) slidably mounted in the cylinder;
a through-shaft fixed on said central axis, said through-shaft being subdivided by the piston into coaxial semi-shafts (4,5) shaped with outer ends with auxiliary pistons (14,15) which slide in inlet chambers (10,11), at least one of the two outer ends of said semi-shafts (4,5) being dovetailed in a connecting rod (16);
said inlet chambers (10,11) being provided with non-return valves (19,20) for permitting the gases to be fed to the inlet chambers and said cylinder being provided with exhaust openings (21) in its central part.

Abstract
The present invention refers to a double-acting, single-cylinder, explosion engine whose peculiarity is to be provided with auxiliary components which permit to optimize the inlet stroke because such auxiliary components are arranged in a way that the gases to be burnt are not inlet by the piston. Such gases are inlet by the auxiliary components.
In general the present engine (1) comprises a cylinder (2) in which a piston (3) may run. The median axis of the piston (3) is interested by a through-shaft which is fixed and coaxial to the piston itself. The shaft is divided in two half-shafts (4, 5) having the same size and shape by the piston.
The half-shafts (4, 5) comprise pistons (14, 15) which may run in inlet chambers (10, 11) and narrowings (12, 13) or holes, openings, leaks or the like through which the inlet gas passes to reach the respective explosion chambers through heads (8, 9). The cylinder (2) is provided with exhausts (21) at its median part.
The above described engine (1) is connected with at least a connecting rod (16) and is able to do two active bursts during a turn of 360° of the connecting rod.
