摘要： A compressor may include a shell assembly, a compression mechanism, a driveshaft, a first bearing, a second bearing, a third bearing, and a surface supporting the third bearing. The compression mechanism may include first and second compression members. The driveshaft may be coupled to the first compression member to rotate the first compression member relative to the second compression member. The first bearing may support the driveshaft for rotation about a first axis. The second bearing may support the driveshaft for rotation about the first axis. The third bearing defines a second axis. The third bearing may support the second compression member for rotation relative to the first compression member. The surface may support the third bearing such that the third bearing is able to roll along the surface to move the second compression member and the second axis in a radial direction relative to the first compression member.

摘要： A compressor according to the principles of the present disclosure includes a shell, a compression mechanism, a driveshaft, a drive bearing cavity, and a drive bearing. The compression mechanism is disposed within the shell and includes an orbiting scroll member and a non-orbiting scroll member. The orbiting scroll member includes a baseplate and a tubular portion extending axially from the baseplate. The driveshaft is drivingly engaged with the orbiting scroll member. The drive bearing cavity is disposed between an outer radial surface of the driveshaft and an inner radial surface of the tubular portion of the orbiting scroll member. The baseplate of the orbiting scroll member defines a first discharge passage in fluid communication with the drive bearing cavity. The drive bearing is disposed in the drive bearing cavity and is disposed about the driveshaft adjacent to the first end of the driveshaft.

摘要： A system may include a compressor including a compression mechanism having first and second compression members defining a compression pocket disposed between the first and second compression members that decreases in volume during operation of the compression mechanism. A heat exchanger receives compressed working fluid from the compressor. An expansion device may be disposed downstream of the heat exchanger. A lubricant separator receives lubricant and working fluid discharged from the compression mechanism and provides separated lubricant to the compression mechanism. A lubricant-injection flow path may include a lubricant fitting and extends between the lubricant separator and the compression pocket such that separated lubricant is injected into the compression pocket through the lubricant fitting.

摘要： A compressor may include a crankshaft, first and second cylinder housings, first and second rotors, a divider plate, and first and second valves. The crankshaft includes first and second eccentric portions. The cylinder housings define cylindrical recesses. The rotors are disposed within respective cylindrical recesses and engage respective eccentric portions of the crankshaft. The first rotor and the first cylindrical recess define a first compression chamber therebetween. The second rotor and the second cylindrical recess define a second compression chamber therebetween. The divider plate may be disposed between the cylinder housings and may include first and second fluid openings in communication with the first and second compression chambers. The valves may be moveable relative to the divider plate between a first position allowing fluid flow through the fluid openings and a second position restricting fluid flow through the fluid openings.

摘要： A compressor may include a crankcase, a crankshaft, a piston, a discharge valve and a suction plenum. The crankcase defines a discharge plenum receiving working fluid at a first pressure. The crankshaft is disposed within the discharge plenum. The piston is drivingly connected to the crankshaft and reciprocatingly received in a cylinder. The piston and cylinder cooperate to define a compression chamber therebetween. The discharge valve may control fluid flow through a discharge passage between the compression chamber and the discharge plenum. The suction plenum may receive working fluid at a second pressure that is less than the first pressure. The suction plenum may provide working fluid at the second pressure to the compression chamber.

摘要： A compressor includes a shell, a first compression member, a bearing housing and a second compression member. The first compression member is rotatable relative to the shell about a first axis. The bearing housing is coupled to the first compression member and rotatable relative to the shell about the first axis. The bearing housing includes a first pin that extends therefrom. The second compression member is rotatable relative to the shell about a second axis. The second compression member includes a base plate and an arcuate-shaped first pin pocket. The first pin pocket is formed in the base plate and receives the first pin. The first compression member is moveable between a first position in which the first pin is engaged with a surface of the first pin pocket and a second position in which the first pin is disengaged from the surface of the first pin pocket.
