    摘要: Several embodiments of combined torsional and elastic couplings for transmitting power from an engine output shaft that experiences torque fluctuations and a driveshaft. In each embodiment, the flexible coupling includes an inertial member that is coupled either elastically or by means of a viscous body to the engine output shaft for absorbing the torsional vibrations. In addition, an elastic coupling couples the engine output shaft to the driveshaft for permitting limited relative rotation to absorb torque flux variations in the engine output shaft.

    摘要: A piston and piston ring assembly has a compression ring and a compression ring groove configured to allow proper mating between the two following thermal expansion. The groove is provided with a substantially horizontal lower face. The ring has a bottom surface that is contoured to provide a cross-sectional angle that substantially matches the anticipated deflection of the lower face caused by thermal expansion. Thus, when the piston expands due to temperature changes associated with operating the internal combustion engine, the lower face deflects away from the combustion chamber. The deflection is absorbed by the pre-contoured bottom surface of the ring. Thus, localized high points between the piston ring and the piston ring groove are reduced and the friction originating at such locations is also reduced. Accordingly, the ring and the groove experience reduced friction and reduced wear while the sealing function of the compression ring is enhanced.

    摘要: A lubricating system for a reciprocating machine such as a two cycle internal combustion engine having the cylinder bores horizontally disposed. A drain system is provided for draining lubricant from the lowermost crankcase chambers to the upper cylinders so as to maintain uniformity of lubrication and insure even and smooth running. A check valve is provided for precluding reverse flow and the lubricant is delivered both to the crankcase chambers and to the piston through either the piston and/or cylinder liner. The lubricant supplied to the piston is supplied at its upper area so as to insure complete lubrication of its circumference and of the associated cylinder bore.

    摘要: Two embodiments of piston constructions for two-cycle, crankcase compression, internal combustion engines wherein the piston is formed with a blow by passage so that blow by gases escaping past the piston rings will not pass across the skirt portion of the piston to deteriorate the lubricant thereon. In one embodiment, holes formed in the piston permit the blow by gases to flow into the interior of the piston and in another embodiment, the piston pin boss is formed with a relief that permits the blow by gases to exit through one of the scavenge passages.
