Title:
SCROLL COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2020/174534
Kind Code:
A1
Abstract:
This scroll compressor is provided with: a shell having a suction pipe for causing a fluid to flow to the inside; a compression mechanism part that has an oscillating scroll forming a compression chamber together with a fixed scroll and that compresses, at the compression chamber, the fluid having flowed in from the suction pipe; a crankshaft that drives the oscillating scroll and that leads, to the compression mechanism part, a lubricating oil of an oil reservoir formed at the bottom of the shell; a driving part that is provided between the compression mechanism part and the oil reservoir and that rotates the crankshaft; and a flow path changing member that has a movable member provided at a position where collision of the fluid having flowed in from the suction pipe occurs and that opens/closes an opening part in accordance with the collision pressure of the fluid, the flow path changing member causing the fluid to flow in a direction toward the oil reservoir by the movable member setting the opening part to a closed state if the collision pressure of the fluid is a first collision pressure, the flow path changing member splitting the fluid by the movable member setting the opening part to an opened state such that the fluid flows in the direction toward the oil reservoir and a direction in which the fluid passes from the opening part, if collision pressure of the fluid is a second collision pressure greater than the first collision pressure.
