A scroll type compressor having a main frame, a sub frame and a crankshaft rotatably mounted in the main frame and the sub frame via a main frame bushing and a sub frame bushing, further includes a fixed scroll and an orbiting scroll cooperable with the fixed scroll to compress gas, the orbiting scroll being drivingly mounted on the eccentric shaft portion. A barrel shaped band portion faces the crankshaft and presents a convex surface in at least one of a respective force direction of a compressive load generated in a compression chamber formed between the orbiting scroll and the fixed scroll, and a reactive force direction of a centrifugal load generated by a revolution movement of the orbiting scroll and rotary movements of upper and lower balance weights. The barrel shaped band portion is formed on the sub frame bushing.

A scroll type compressor which includes a compression unit, a crankshaft having an oil passage therein, and an electric motor stator having an oil return hole. An oil pump feeds oil into the oil passage of the crankshaft, and an oil drain tube receives return oil from the compression unit and feeds the oil to the oil return hole of the electric motor stator. The drain oil tube advantageously includes an upper nonflexible drain opening which receives oil from the compression unit. The oil then passes through a nonflexible portion which includes a bend or bent portion, and then to a flexible portion which extends from the elbow into the oil return hole of the electric motor stator.

A scroll type compressor which includes a spacer between the fixed scroll base plate and the frame, with the spacer disposed about the orbiting scroll. The spacer is coupled to the fixed scroll and frame, and can be coupled to a center shell of the compressor, for example, by a shrinkage fit. Further, one or more bolts extend from the fixed scroll base plate through the spacer and into the frame. In addition, one or more bolts can be provided which extend from the spacer to the frame to provide for positioning of the spacer with respect to the frame.

The invention concerns a high-reliability scroll compressor with little moment for making a fixed scroll unstable. A scroll compressor comprising in a sealed vessel a fixed scroll, an orbiting scroll being combined with the fixed scroll for forming a compression space, and executing orbiting motion with respect to the fixed scroll, a frame for axially supporting the orbiting scroll and radially supporting a drive shaft, and a seal member being disposed in an axial gap between a high and low pressure separator stuck to the frame by any method and the fixed scroll, wherein a base plate outer peripheral surface of the fixed scroll is radially supported by a stationary member coaxial with the base plate outer peripheral surface, and wherein with the stationary member as a guide, the fixed scroll can make axial movement within a range in which it interferes with the orbiting scroll downward in the axial direction and with the high and low pressure separator upward in the axial direction.
