ABSTRACT:
Engines, pumps and compressors having one or more pistons mechanically connected to a crankshaft (30; 100; 200) incorporates an eccentric disc (35, 35; 111, 112; 210) skewered by and mounted on a crankshaft crankpin (34; 101; 201-203). The eccentric disc is either a part of the piston (220) or is itself the piston (35, 36; 111, 112), and it tangentially engages the internal sidewall (42, 43) of the cylinder or "piston Chamber" so as to receive the brunt of the piston side force. The eccentric disc may also include a freely rollable peripheral portion (90; 115) to minimize internal frictional resistance and wear. The embodiment of FIG. 3 additionally features the combination of double-acting pistons; a four-to-one piston-stroke to crankpin-offset ratio; and two 90.degree. out-of-phase eccentric discs rigidly connected together side-by-side with each eccentric disc contained in a different piston chamber that are banked 90.degree. from one another. A completely sealed (48, 49, 63, 67, 73) lubrication system (64, 65, 68, 69, 70, 71, 76, 77, 78, 79, 80, 81, 83) forcibly lubricates crankshaft bearings (46, 47, 62, 66).
