AIR COMPRESSOR WITH MULTI-TYPE CONNECTING ROD

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air compressor having a multi-type connecting rod, and more particularly to a novel concept of arranging a plurality of connecting rods, which are connected to a reciprocating piston inserted in a crankshaft used in a reciprocating air compressor, . In the conventional air compressor, since the length of the crankshaft is longer than necessary and the cylinders are arranged at intervals in the front-rear direction, the external shape of the compression pump becomes larger as the number of cylinders increases, A bearing for preventing the frictional resistance of the bearing is required. In order to solve such a problem, the present invention proposes a method of connecting a fixed linking link integrally formed at the upper end of a large end portion of a multi-type connecting rod to a piston in one of the cylinders, The detachable connection link selectively connected to the required number of recesses is characterized in that the fixed connection link and the detachable connection link can be arranged in a straight line along the mutually circumferential direction when the piston is connected to the piston in another cylinder .

[Class 8 (i).] Sets of radial compression cylinders 3, 4 are formed in a block, each set delivering the air at a different predetermined pressure. The pistons are actuated by an eccentric 5. The larger cylinders 3 draw through valves 9 from an annular suction chamber 10, and deliver to a low-pressure receiver 12 ; a byepass 14 fitted with a spring-controlled valve 15 returns the air to the suction chamber at a certain receiver pressure. The small cylinders deliver from the suction chamber 10 to a highpressure receiver 13 from which the air is similarly byepassed to the suction chamber on attaining a certain higher pressure. The receiver 13 opens into an outlet manifold by a free passage, and the low-pressure receiver 12 opens into the manifold by a passage having a spring-actuated valve. Delivery takes place from both chambers 12, 13 till at a certain pressure the byepass valve is opened and so the valve leading to the outlet is closed; while at a certain higher pressure the receiver 13 is byepassed.

Efficiencies for cam-drive piston engines or machines

Disclosed are crankshaft, single-plate cam and beam mechanisms that provide significant improvements in performance for 2 & 4-stroke engines, compressors and pumps. These cost effective mechanisms include linkages with the new and improved use of pivoting arms that operate with a variety of cylinder arrangements. One embodiment of the crankshaft mechanism has its crankpin roller positioned within a novel yoke-arm. The cam mechanism uses a pair of centrally positioned parallel links that are connected to roller cam followers and single or diametrically-opposed pistons. A pair of laterally extending follower arms connects to the ends of the links to provide support and alignment for the piston rods. Between the reciprocating links, cam followers and follower arms is a rotating odd-lobe plate cam.
