Composite piston machine combining rotary oscillating and pendular movements

A composite piston machine comprising:

• a. a main body comprising an inner cavity and the main body defining one or more inlet ports allowing for inlet of fluids to said inner cavity and defining one or more outlet ports allowing for outlet of said fluids from said inner cavity;
• b. two lids closing said inner cavity, each lid having an inner face, and an outer face, each said inner face comprising a skid guide and a bearing cavity;
• c. a separator having two faces each facing an opposing inner face of one of the two lids and each separated from the opposing inner face of one of the two lids by a lid-separator distance, said separator dividing said inner cavity into two working chambers, said separator comprising a skid guide on each face, and a separator bearing cavity traversing the separator from one face to the other;
• d. three bearings, one of these bearings inserted in each lid bearing cavity and one bearing disposed in the separator;
• e. a shaft linked to said three bearings;
• f. in each of said two working chambers, a rotor having a radius and a depth, each said rotor being linked to said shaft 180° out of phase with the other rotor;
• and
• g. in each of said two working chambers, a composite piston comprising a piston head and a piston body, said piston body having two skids, said piston body inserted within a piston guide radially carved in each said rotor, and said skids inserted in said piston guides, said piston heads separating said working chambers into inlet chambers and outlet chambers of variable volume;
• wherein said rotors move linked to said shaft and impulsed by said composite pistons whose skids follow the path of said piston guides, altering the volume of said inlet and outlet chambers and intermittently obstructing inlet and outlet of said fluids from said inner cavity.
