    Abstract: 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.

    Abstract: A bearing system includes a bearing housing that includes a sleeve and a mounting structure for connecting the bearing system to a compressor housing. The sleeve has a radial inner surface that defines a cylindrical bore, and includes a locking feature located along the radial inner surface. The mounting structure is located radially outward from the sleeve. The bearing system also includes a foil bearing assembly positioned within the cylindrical bore. The foil bearing assembly includes an outer foil, an inner foil, and a bump foil positioned between the outer foil and the inner foil. At least one of the outer foil and the inner foil includes a bearing retention feature cooperatively engaged with the locking feature to maintain the foil bearing assembly within the bearing housing at a fixed rotational position.

    Abstract: 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.

    Abstract: A compressor may include a first scroll member, a second scroll member and a drive shaft. The first scroll member may include a first end plate defining a first discharge port and a first spiral wrap extending from the first end plate. The second scroll member may include a second end plate defining a first variable volume ratio port and a second spiral wrap extending from the second end plate and meshingly engaged with the first spiral wrap and forming compression pockets. The variable volume ratio port may be located radially outward relative to the first discharge port and in communication with a first compression pocket. The drive shaft may be engaged with the second scroll member and driving orbital displacement of the second scroll member relative to the first scroll member.
