SCROLL-TYPE COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2015/056432
Kind Code:
A1
Abstract:
A scroll-type compressor is provided with: a movable scroll (11) having a spiral-shaped low-stage-side movable tooth part (11b) protruding toward an axial first side of a movable substrate part, and a spiral-shaped high-stage-side movable tooth part (11c) protruding toward an axial second side of the movable substrate part; and a shaft (25) arranged so as to pass through the movable substrate part, the shaft (25) allowing the movable scroll (11) to undergo orbital motion, a low-stage-side compression mechanism and a high-stage-side compression mechanism being configured on both axial sides of the movable substrate part. Furthermore, the the low-stage-side movable tooth part (11b) and the high-stage-side movable tooth part (11c) turn once, a low-stage-side compression chamber (VL) in the low-stage-side compression mechanism is configured from a single space when interconnected with an intermediate-pressure discharge hole (12d), and a high-stage-side compression chamber (VH) in the high-stage-side compression mechanism is a single space when interconnected with a high-pressure discharge hole (13d). Increases in energy loss can thereby be suppressed with a simple configuration.
