A reciprocating refrigerant compressor system is disclosed. The compressor system includes a cylinder, a piston disposed within the cylinder, at least one fluid passageway, and an actuator. The piston is movable between a bottom dead center (BDC) and a top dead center (TDC) position. The fluid passageway is disposed within the cylinder between the BDC and TDC position and defined by one or more apertures. The actuator is in operative communication with the aperture and is responsive to an environmental condition external to the compressor system to at least partially close the aperture.

Variable capacity compressor and refrigerator

The valve assembly for a rotary compressor includes an elongated valve member which rests on pads on each side of the valve seat and includes an intermediate sealing section normally sealing against the valve seat. An elongated valve spring biases the sealing section toward engagement with the valve seat. An elongated spring backer sits on one end of the valve spring and the other end of the valve member. One end of each of the valve member, valve spring and spring backer are bolted to the compressor end plate. The other end of the spring backer permits the corresponding end of the valve member to slide along the end plate as the valve member moves between its open and closed positions, while restraining the end of the valve member from moving away from the end plate. A backer support, positioned between the spring backer and the head of the bolt, spreads the clamping force and defines a line about which the valve member and valve spring flex.

Rotary compressor with span type discharge valve

A rotary compressor comprising a cylindrical chamber, a vane slidably mounted in the peripheral cylinder wall and a torsion spring to bias the vane into contact with an eccentrically mounted roller. The spring includes an elongated central portion and a pair of arms extending from the central portion in parallel planes. The arms are curved or radiused in opposite directions. The central portion is connected to the outer edge of the vane while the ends of the arms are connected to opposite side of the cylinder so that the arms exert a torsional force on the central portion.

Torsional vane spring

A rotary compressor includes a cylinder with a cylindrical compression chamber. A cylindrical piston is eccentrically movable within the chamber. A vane slot extends outwardly in the cylinder from and communicates with the chamber. A vane is reciprocatingly mounted in the vane slot for selective protrusion into and retroaction from the chamber to contact the piston. At least one noise reduction slot projects into the cylinder from its outer peripheral wall near the vane slot and extends completely between the ends of the cylinder.

Compressor with an isolated vane slot

A hermetically sealed compressor unit includes a hermetically sealed casing having a side wall with a cylindrical inner surface; an electric motor is positioned within the casing and includes a stator with a cylindrical outer wall having an interfering fit with the casing side wall inner surface; a rotary compressor unit driven by the motor includes a cylinder spaced from the motor and having a cylindrical outer wall welded to the casing side wall at selected positions; and at least one stiffening ring positioned adjacent the cylinder and having a cylindrical outer wall of a larger diameter than said cylinder outer wall and having an interfering fit with the casing side wall inner surface.

Motor-compressor with means to reduce noise

A hermetically sealed rotary refrigerant compressor, comprising a compression chamber, a roller eccentrically rotatable in the chamber, and a vane slidably mounted in a slot in the wall of the chamber dividing the chamber between a low pressure suction side and a high pressure compression side including means for modulating the pressure differential between the low pressure suction side and the high pressure compression side of the vane at a preselected time in the compression cycle so as to minimize the frictional forces between the vane and vane slot caused by the pressure differential in the chamber.
