Abstract: A crankshaft having at least two eccentric members of different diameter and a method of assembling a reciprocating compressor using a crankshaft having at least two eccentric members of different diameter are provided. A crankshaft having two eccentric members of different diameter is provided for more easily assembling a four-cylinder reciprocating compressor. The eccentric member having a smaller diameter is more easily inserted through apertures of connecting rods having a larger diameter than the eccentric member.

Abstract: A compressor unit having a housing consisting of steel inner and outer shells, the shells being spaced apart from each other to provide an attenuation cell substantially occupying all of the space between the shells, a suction gas inlet and a discharge gas outlet extending through both of the shells and the cell and being isolated from the outer shell by sound absorbing means, and spacer material having sound absorbing properties positioned between the shells and maintaining the spacing therebetween, the spacing being, preferably, at least about 0.06 in. in width over at least a major portion of the cell.

Abstract: A shell for a hermetic compressor unit, the shell having a top section or dome, and a bottom section, the dome having a unique shape which gives enhanced capacity for absorbing and attenuating structural and fluid transmitted wave energies emanating from the unit at wave frequencies of between 1,000 Hz and 2,000 Hz, while reducing total operating noise of the unit, the dome being formed of sheet metal and having a generally inverted cup-shaped configuration with generally cylindrical sidewalls and a top wall having a central portion surrounded by a peripheral portion, wherein the sidewall taken in a generally axial direction is substantially straight, wherein the central portion of the top constitutes from about 40 to about 90% of the total area of the top and has a generally hemispherical configuration on a mean radius of from about 6.5 to about 10.0 inches as measured from an origin point O.sub.

Abstract: A gas compressor having a block with two opposed cylinder banks each having at least one cylinder formed therein, each bank having an upper end, a lower end, an inner wall, an outer wall, and opposite side wall, a floor interconnecting the cylinder banks at their lower ends, and a roof interconnecting the cylinder banks at their upper ends, a crankcase formed by the inner walls, roof and floor, the crankcase having a longitudinal axis extending through the roof and floor, first bearing positioned on the floor and aligned with the longitudinal axis for rotatably mounting one end of a crankshaft, an aperture through the roof, a second bearing positioned on the roof and aligned with the longitudinal axis for rotatably mounting the other end of the crankshaft through the aperture, a piston mounted in each cylinder and each having a connecting rod mounted on the crankshaft, the adjacent edge portions of the inner wall, the side walls, the floor and the roof defining an access portal to the crankshaft and to the co

Abstract: A discharge muffler construction having a casing which defines a noise attenuation cavity and which is provided with an inlet and outlet located at substantially opposite portions thereof and communicating with the cavity, a baffle plate in the cavity intermediate the inlet and outlet and partitioning the same into at least two chambers, the baffle plate having an arcuate surface concave to the inlet, an aperture through the baffle plate, and a tubular conduit mounted through the aperture and placing the chambers in fluid communication.
