Abstract: A hermetic compressor may include a crankshaft having an input shaft rotatably supported on the cast-iron block along the crankshaft axis and connected to the electric motor rotary output, and an eccentric crankpin orbitally rotating about the axis as the crankshaft is rotated. A pair of opposed pistons may lie on the common plane. Each piston may be pivotably connected to one of the connecting rod piston ends to drive the pistons in an oscillatory manner within the cylinders as the crankshaft rotates. The piston and cylinder pairs may cause fluid to be pumped from the inlet port to the outlet port as the piston oscillates varying the volume of the enclosed space bound by the piston and the cylinder pairs.

Abstract: Compressor with double compression chamber and gas purification process, having a set of movable mechanisms and fixed parts, and procedures for the preparation of refrigerators and hermetic compressors before filling with refrigerant gas, which greatly enhances the energetic efficiency and useful life of refrigeration compressors. Additional, by adding a process tube, made of copper, steel, or any other appropriate material to the side wall of the hermetic or semi-hermetic compressor, on its bottom, or attached vertically to the central base of the compressor. This additional tube and the traditional suction tubes, discharge process, follows an alternative construction format to enhance the efficiency and useful life of a refrigeration system.

Abstract: This is a dynamic system for refrigeration equipment. This invention provides special features, including a set of mechanisms, electro-mechanisms, and electronic controls for refrigeration compression chambers or other kinds of fluids that employ two, three, or four compression chambers. There is extremely low vibration, noise, cost, and energy consumption in this equipment. It does not overheat and has a reduced size, lightweight and requires less raw materials to build it. There are other advantages in its technical aspects. It can be run on an electric motor or only with solenoid coils for traction. The applications include, but are not limited to, refrigerators, freezers, air conditioners, cold stores, refrigerated trucks, compressors for automotive air-conditioning, etc. Other applications include those that normally require a piston (piston-air compressor or diaphragm compressor to fill tires, spray painting, etc . ).

Abstract: It refers to the special features of this invention, which are a set of mechanisms, electro-mechanisms, and electronic controls that allow a compression chamber for a refrigeration fluid or other kinds of fluids to employ three, six, or even double that number of chambers. The equipment runs at an extremely low vibration (even annulled is possible), little noise, it does not overheat, small size, lightweight and requires a smaller quantity of raw material to build int. There are other advantages regarding the technical aspects. It can be built using an electric motor or only solenoid coils for traction. This makes the manufacturing of compressors faster, lower cost. Making it a much better product. (This is a better compressor), which supplies compression for fluids at a lower energy cost, low vibration (even annulled is possible), runs quietly, it does not affect the atmosphere adversely, and it is highly efficient.
