Abstract: A crankshaft and connecting rod assembly comprises a driver having a crank lobe with a shank received in a radial slot through a shaft so as to be driven thereby. The crank lobe has an inner side that operably contacts the shaft and an outer side that operably contacts a bore in a connecting rod and the shank has an end that also operably contacts the bore. The outer side of the crank lobe and the end of the shank each have a semi-circular cylindrical surface and these surfaces are located diametrically opposite each other and have a common axis eccentric and parallel to that of the shaft and a radius substantially equal to that of the bore whereby upon shaft rotation the crank lobe through sliding contact with the bore drives the connecting rod while the end of the shank slidingly follows the bore and cooperates with the crank lobe to prevent radial movement of the driver on the shaft to thereby maintain such drive.

Abstract: An axial piston swash plate refrigerant compressor is provided with a discharge gas baffle and pulse attenuation device that reroutes the discharge gas from one discharge cavity away from the compressor outlet to meet with that from another discharge cavity in an attenuation chamber and thereafter further attenuate the combined discharge prior to delivery to the compressor outlet.

Abstract: A variable displacement wobble plate compressor is disclosed having a bearing body with a slot and cylindrical guide surfaces such that the bearing body operates directly between a guide rod and a wobble plate to prevent rotation while permitting angulation of the latter.

Abstract: A variable displacement wobble plate compressor is disclosed having vibration isolation mounting cups supporting the opposite ends of a guide rod that operates through a multiple axis joint to prevent rotation while permitting angulation of the wobble plate.

Abstract: A swash plate compressor is disclosed having integral plastic ball and shoe parts with opposing working surfaces of equal area providing the drive between the opposite sides of the swash plate and the inner ends of double-ended pistons that straddle the plate.

Abstract: A hydraulic radial piston pump has intake porting comprising a slot in the face of a slider block communicating with a passage extending axially through the piston.
