摘要： A two-stage reciprocating compressor is provided. The compressor includes a block with a single cylinder and associated single compression chamber and single piston. The compressor further includes a crankshaft. The crankshaft has an eccentric crankpin that is operatively connected to the piston. A reversible motor is provided to rotate the crankshaft in a forward direction and in a reverse direction. An eccentric cam is rotatably mounted on the eccentric crankpin. The eccentric cam is held stationary with respect to the crankpin when the crankshaft is rotating in the forward direction. When rotating in the forward direction, the crankshaft drives the piston at a full stroke between a bottom position and a top dead center position. The eccentric cam rotates with respect to the crankpin when the crankshaft is rotating in the reverse direction. When rotating in the reverse direction, the crankshaft drives the piston at a reduced stroke between an intermediate position and the top dead center position.

摘要： A two-stage reciprocating compressor is provided. The compressor includes a reversible motor that rotates a crankshaft. The crankshaft is connected to a piston by a mechanical system. The mechanical system drives the piston at a full stroke between a bottom position and a top dead center position when the motor is operated in a forward direction. The mechanical system drives the piston at a reduced stroke between an intermediate position and the top dead center position when the motor is operated in the reverse direction. The compressor also includes a control for selectively operating the motor in either the forward direction at a first preselected, fixed speed or in the reverse direction at a second preselected fixed speed.

摘要： For a refrigerant compressor having two capacities, a camming structure operable in different manners depending on direction of crankshaft rotation, to achieve each capacity while providing top dead center piston operation thru the use of a circular cam bushing which is eccentrically, rotatably mounted on the crankshaft eccentric and within the connecting rod bearing wherein the combined eccentricities of the bushing and the eccentric equal the primary stroke of the piston. A first stop mechanism is provided for stabilizing the bushing on the eccentric upon rotation of the crankshaft in one direction whereby the eccentricities of the eccentric and bushing become aligned and remain so during synchronous rotational orbiting motion of the eccentric and bushing during rotation of the crankshaft for producing full stroke and full capacity. A second stop mechanism is provided for stabilizing the bushing within the bearing upon opposite rotation of the crankshaft whereby the bushing eccentricity becomes and remains substantially aligned with the connecting rod stroke axis while the eccentric moves alone thru its rotational orbit for producing reduced stroke and reduced capacity. A unique electrical control system is also provided for a reversible electric induction motor for selectively and efficiently driving the compressor crankshaft in either direction for providing the different capacities.

摘要： An automatic self-modulation capacity compressor for an HVAC&R system is disclosed. The system includes a housing, a compressor, a motor, and a pressure sensitive control valve. The HVAC&R system further comprises an expander and a condenser. In the open position, the control valve permits a portion of the pressurized gasses from the compressor to escape, creating a partial capacity compressor within the system. Once a predetermined set point pressure differential is met, the control valve moves to the closed position, where all of the pressurized gasses within the compressor are provided to the system, thereby creating a full capacity compressor. Once the compressor is operating in full capacity, the compressor remains in full capacity mode until the demands of the system are met and the compressor shuts down. Upon restart, the compressor operates in partial capacity until the predetermined set point pressure is met once again and the compressor begins operating in full capacity.

摘要： A compressor with a capacity modulation system includes a compression chamber, a rotatable shaft within the compression chamber, and a roller mounted on the shaft in contact with a wall of the compression chamber. A suction channel is in fluid communication with the compression chamber for providing fluid at a suction pressure and a discharge channel is in fluid communication with the compression chamber for removing fluid at a discharge pressure. A re-expansion channel adjacent to the compression chamber has a first end forming a re-expansion port in the wall of the compression chamber. A re-expansion chamber is connected to the re-expansion channel. A valve disposed in the re-expansion channel is movable between a first position, in which the valve allows fluid communication between the compression chamber and the re-expansion chamber, and a second position, in which the valve prevents fluid communication between the compression chamber and re-expansion chamber.

摘要： A system and method of sizing an inner diameter of the center bore of a laminated rotor is provided. The inner diameter of the center bore is determined by taking a series of measurements in the center bore with an electronic gauge and then analyzing the measurements to determine the acceptability of the rotor. The electronic gauge is inserted into the center bore of the rotor and measurements of the inner diameter of the center bore are taken at a variety of different depths and positions using the electronic gauge. The measurements are then analyzed to determine if the rotor is acceptable for use by evaluating the measurements with respect to a reference diameter and a depth in the center bore.

摘要： A method of assembling and manufacturing a laminated rotor is provided which uses laminations having a thin bridge thickness. Different techniques are provided for preventing the molten material used in the casting or injection molding operation from leaking or seeping between the laminations during casting. In one technique, the laminations are stacked and oriented in the conventional way, and then both axial and radial pressures are applied to the stacked laminations to hold the laminations in position for the casting process. In another technique, the laminations are formed or extruded with a lip or collar portion that fit in a countersunk portion of an adjacent lamination and forms a wall or barrier between the laminations to prevent the leakage of the molten material during the casting or injection molding operation.
