Scroll compressor with axial biasing

摘要

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. 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 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.
