  • Patent number: 7374406
    Abstract: A method and system is provided for reducing chatter in multi-capacity compressors having disengageable eccentric structures. The multi-capacity fluid compressor includes a compression chamber having a discharge end and an inner surface. The compressor also includes a compression member having a disengageable eccentric structure allowing the compressor to provide discrete compression capacities. A valve portion is disposed adjacent to the discharge end of the compression chamber and is arranged and disposed to discharge a compressed fluid when the compression member has completed. A discharge arrangement is arranged and disposed to discharge at least a portion of fluid remaining in the compression chamber at the completion of the compression cycle. The discharge of at least a portion of the fluid remaining in the compression chamber reduces or eliminates forces on the disengageable eccentric structure to limit rotational acceleration of the disengageable eccentric structure.

  • Patent number: 7281907
    Abstract: A single piece offset mounting foot is positioned between the compressor and the floor of a cabinet for the compressor. The offset mounting foot has a main body having a geometric shape with a top and bottom surface connected by sidewalls that form a perimeter. A depression in the top surface receives a compressor and is offset in the direction of one of the sidewalls. A plurality of substantially equally spaced legs extend outward from the main body. The thickness of the offset mounting foot may be substantially uniform through the main body. The profile of the top surface in the main body is substantially concave forming a bowl-like surface that transitions smoothly from a minimum within the concave surface or concavity to a maximum in the direction toward the periphery and in the direction away from the center of the concavity. The bottom surface of the main body is configured or profiled to contact the floor or base of the cabinet into which the compressor is to be installed.

  • Patent number: 6935848
    Abstract: A muffler system for a compressor includes an expansion chamber muffler for attenuating sound pressure pulses and an acoustic muffler for filtering high-frequency pressure pulsations. The acoustic muffler is connected inline along the discharge side of the compressor between the discharge port of the cylinder head and a discharge tube in fluid communication with the outlet port of the compressor housing. A conduit is in fluid communication between the outlet port of the compressor housing and the condenser to supply the flow of refrigerant therebetween. Interposed adjacent the compressor housing, but exterior to the compressor housing is an expansion chamber muffler in fluid communication with the conduit for further attenuating pressure pulses generated by operation of the compressor.

  • Patent number: 6935221
    Abstract: A die cast aluminum piston for a reciprocating compressor. The piston is cast with no coring and thus includes no aperture in the as-cast piston for a wrist pin. The aperture for the wrist pin is subsequently formed in the wrist pin in a preselected location after casting. The wrist pin is formed of a preselected diameter. Because the wrist pin can be placed in a preselected location with a preselected diameter, the same cast piston design can be used in a plurality of applications by varying the location of the aperture or the size of the aperture, or both.

  • Patent number: 6840746
    Abstract: A resistive muffler attenuates sound generated by the gas intake and suction valve during compressor operation of a refrigerant compressor. The resistive muffler is assembled inline with the suction gas flow of the compressor and is positioned within the compressor housing. The resistive muffler attenuates the sound generated by the compressor during its operation as refrigerant gas is drawn into the compressor from an evaporator and passes through the resistive muffler in transit to the suction valve and hence to the region of the compressor where the gas is physically compressed. The resistive muffler includes a muffler housing having an intake end and an exhaust end. An acoustic foam assembly is incorporated into the muffler housing.

  • Patent number: 6781342
    Abstract: A three phase motor starting system is provided to reduce the in-rush current to the motor in order to obtain a soft start of the motor. The soft start of the motor equates to reduced impact forces on motor parts and device components connected to the motor during startup of the motor, especially a startup resulting from a reversal of the direction of rotation of the motor. The system uses an impedance load in series with the motor windings of the motor to reduce the in-rush current to the motor windings, which results in a reduced acceleration of the motor shaft and a soft start to the motor. The impedance loads used by the system can be a resistive load, a capacitive load or an inductive load, depending on the type of impedance load that is desired for the soft start of the motor.

  • Publication number: 20040055458
    Abstract: A reciprocating compressor having a linear motor, at least one piston and cylinder arrangement and a mechanism operatively connecting the linear motor to the piston and cylinder arrangement is provided. The piston and cylinder arrangement operate to compress a fluid, preferably a refrigerant gas. The piston and cylinder arrangement has a cylinder, a piston configured and disposed to travel in the cylinder and a piston rod connected to the piston. The mechanism connects the linear motor to the piston rod to move the piston in the cylinder upon operation of the linear motor. The mechanism is configured and disposed to limit overtravel of the piston in the cylinder in response to a light load of the reciprocating compressor and to limit undertravel of the piston in the cylinder in response to a heavy load in the reciprocating compressor.
