ABSTRACT:
A fluid motor or pump that has a front wall, four corner conduits, two lateral conduits, a chamber, two pistons, a piston rod and a crank, in which the rotary motion of the crank is transformed to a vertical sliding motion of the chamber and a horizontal sliding motion of the pistons, that result in continuous fluid motion or vice versa. The front wall supports the crankshaft and the corner conduits. The corner conduits hold and communicate with the lateral conduits. The lateral conduits communicate with the chamber internal areas and allow the chamber to slide. The chamber controls the fluid flow and allows the pistons, joined by the piston rod, to slide. The pistons' sliding motion causes the fluid to flow and the piston rod to move. The piston rod movement causes continuous rotary motion of the crankshaft or vice versa.
