A SYSTEM FOR THE CONSTRUCTION OF PUMPS, COMPRESSORS, AND MOTOR ENGINES, FORMED BY A ROTARY CHAMBER AND PISTONS WHICH ARE DRIVEN IN THE SAME DIRECTION AT VARYING VELOCITIES ALTERNATIVELY OPPOSITE TO EACH OTHER, INSIDE A FIXED OPEN OR CLOSED STRUCTURE

摘要

The present invention refers to a system for the construction of pumps, compressors and motor engines, consisting of a rotary chamber and pistons which are driven in the same direction at varying velocities alternatively opposite to each other, through an adequate mechanism of alternatively opposite variation of velocities inside a fixed open or closed structure. The new system is characterized by the chamber not being fundamentally fixed. On the contrary, it is rotative, preferably formed by two rotary half-chambers, which at least have a displacer or a piston each, jointed to each one of them, closing its own half-chamber and penetrating by sliding in the hollow of the other half-chamber, creating at least two compartments that alternatively vary their volume. The axes of each rotary half-chamber move inside a fixed structure that supports them. This structure may be open or contain a hermetically closed department. In one of its versions, the structure bears a ring, where the openings for the intake and outlet of fluids are located. Placed against the sides opposite to this ring, runs each rotary half-chamber, closing the main chamber. At least one piston or displacer fixed to each half-chamber seals up a sector of the same and introduces itself in a sliding way in the other rotary half-chamber, dividing the chamber into at least two compartments. When these are set in motion by an adequate mechanism (sliding arms, eccentric gears, elliptic, planetary gears, etc.), they alternatively vary their volume.
