Abstract
The present invention relates to highly efficient suction and compression rotating mechanisms, particularly the compression mechanism with piston blocks mounted on two axes and driven by a pair of matching gears in the field of compressors and vacuums or hydraulic system such as oil pump, hydraulic motor, hydraulic gearbox, specifically there is application that uses this mechanism to create one rotary motor with multi compression stages, force-generating stages and continuous fuel burning regime. The new rotary lobe structure in this invention provides a close contact between curved surfaces with the same radius, which is a “Surface-to-surface” contact, with much better tightness than “line” contact.

A rotary suction/compression mechanism includes:
- a chamber formed by a casing around two symmetrical parallel overlapping cylindrical spaces bounded by opposite end walls;
- two shafts located at center-lines of the two cylindrical spaces, driven by a pair of matching gears affixed to the shafts;
- two bearing plates fastened on the two shafts and located in a middle of the chamber between the end walls, each of the bearing plates having sides facing the end walls and a diameter approximately equal to an inner diameter of the cylindrical spaces of the pump chamber casing;
- fixed hollow cylinders protruding from each of the end walls around each of the shafts, entering the cylindrical spaces between the end walls and the bearing plates, wherein tops of the cylinders are close to side surfaces of the bearing plates, center-lines of the cylinders coincide with the center-lines of the shafts, and outer diameters of the cylinders are less than the inner diameter of the cylindrical spaces of the chamber casing, leaving room between the cylinders and the chamber casing;
- the pistons mounted in pairs symmetrically on opposite sides of each of the bearing plates and in pairs symmetrically across the centerline of each of the shafts, wherein the outer diameters of the pistons are approximately equal to the diameter of the bearing plate and the inner diameter of the cylindrical spaces of the chamber casing, the inner diameters of the pistons are approximately equal to the outer diameter of the cylinders protruding from the end walls, and the pistons are arranged such that when operating, the pistons on both sides of the bearing plates will rotate around the two pump shafts in the room between cylinders and the chamber casing;
- wherein heights of the pistons are approximately equal to corresponding heights of the cylinders and the thicknesses of the pistons fill the room between the cylinders and the chamber casing, such that sealing of the pistons is by surface-to-surface contact.
