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 to the drive scroll rotational axis. Further, at least one compression chamber (30) is preferably defined between the drive scroll and the driven scroll. A first bearing (14) may rotatably support the drive scroll in a cantilever manner and a second bearing (24, 115) may rotatably support the driven scroll in a cantilever manner. A transmission (31, 131, 231 and 331) or other device may be provided to rotate the drive scroll in synchronism with the driven scroll.
