<p>The invention relates to a column-type multi-piston. The inventive multi-piston consists of an assembly comprising two cylinders which are connected lengthways. The aforementioned cylinders are separated by a barrier comprising a central hole. A common shaft, which passes through said hole, connects two double-action pistons, each piston being housed in one of the cylinders. The lower end of said common shaft transmits the impulse force, which is generated by the ignition of the fuel mixture, to a crank. Admission, compression, ignition and expulsion operations are performed in each of said double cylinders with dual pistons. Since the inventive device does not use a crankshaft, a connecting rod receives the force from the pistons, transmits said force towards the common shaft and transforms same into a rotary force by means of a crank. The invention can be used as an engine, a compressor and a vacuum pump. As a result of its simplified design, the number of parts used, the size of the device and the production, maintenance and operation costs thereof have all been reduced.</p> |
