The Compact Non Vibrating Endothermic Engine (CoNVEE in the following) is an internal combustion engine with reciprocating motion of the pistons, whose innovative architecture makes it more compact, given the same delivered power, with respect to the current state of the art. This happens both because the CoNVEE core occupies a very reduced volume, and also because it does not require the presence of any additional compensation or damping of mechanical vibrations. In fact all the moving parts of the CoNVEE are already internally compensated: they act in perfect anti-symmetry compensating each inertia force developed, excluding, of course, that of the motor shaft which is indispensable for the generation of the useful mechanical energy. The intrinsic compactness of the CoNVEE is made possible by the new and characteristic mechanism adopted for the motion transfer from the pistons to the motor shaft. The CoNVEE may be conveniently used with any type of propulsion fuel and, particularly, for those applications which require high power density and low vibration in the motor. |

1. An internal combustion two-strokes engine comprising at least one cylinder with two pistons inside, facing each other
said two pistons have, having an axial reciprocating motion, and characterized in that: when said two pistons move towards the ends of the cylinder, each of said two pistons pushes towards outside the cylinder a “T-rod”, each of said two “T-rods” comprises a stem parallel to the direction of motion of said two pistons and two arms; said stem is fixed, on one end, to the piston's back and, on the other end, it is fixed to said two arms that fork in opposite directions and said two arms are terminated with tappets or rollers; the movement of said stem of said “T-rod”, referred to the frame of said engine, is purely axial along its axis without any rotation and said stem slides across a hole obtained in the wall that closes the end of said cylinder, to achieve a pre-compression chamber; said internal combustion two-strokes engine, at each end of each cylinder has a “T-rod guidance” element which is fixed to the frame of the engine, and said “T-rod guidance” binds said arms of the “T-rod”, so that said “T-rod” and said relative fixed piston can slide along the axial direction of the cylinder housing said piston, being prevented by said guidance to spin around said cylinder's axis; said internal combustion two-strokes engine comprises also a hollow cylindrical cam associated to each piston; a straight motor shaft is coupled via gear trains, or other similar mechanisms to said two hollow cylindrical cams for the transfer of the motion, and its axis is parallel to the axis of said cylinder. |
