Title:
VORTEX COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2017/202385
Kind Code:
A1
Abstract:
A vortex compressor, comprising a fixed vortex (150) and an orbiting vortex (160); the fixed vortex (150) comprises a fixed vortex end plate (154) and a spiral-shaped fixed scroll (156) extending from the fixed vortex end plate (154); the orbiting vortex (160) comprises an orbiting vortex end plate (164) and an orbiting scroll (166) which extends from the orbiting vortex end plate (164) and which engages with the fixed scroll (156) to form a compression chamber. The fixed scroll (156) comprises a first fixed scroll portion (156a) on a radially outer side and a second fixed scroll portion (156b) on a radially inner side; the first fixed scroll portion (156a) is periodically covered by the orbiting vortex end plate (164) while the vortex compressor is operating, and the second fixed scroll portion (156b) is always covered by the orbiting-vortex end plate (164) while the vortex compressor is operating. A sealing member is provided on one of the first fixed scroll portion (156a) and a first covering portion (164a) of the orbiting vortex end plate (164) corresponding to the first fixed scroll portion (156a). A radial space of a compressor having such a structure can be fully utilized; thus, displacement may be increased while exhibiting good sealing performances.
