Abstract
Scroll compressors (1) may include a housing (2, 3) having an inlet port (3a) and an outlet port (3b). A drive scroll (10) may be rotatably disposed within the housing and may have a rotational axis. A driven scroll (20) may be rotatably disposed within the housing and may have a rotational axis. The driven scroll rotational axis preferably is offset with respect to the drive scroll rotational axis. Further, at least one compression chamber (30) is preferably defined between the drive scroll and the driven scroll. First bearings (14, 16, 16a) may rotatably support one of the drive scroll and the driven scroll in a straddle manner. A second bearing (24) may rotatably support the other of the drive scroll and the driven scroll in a cantilever manner. A transmission (31, 131, 231 and 331) or other device may be provided to rotate the driven scroll in synchronism with the drive scroll.
