Title:
SCREW COMPRESSOR AND REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/192114
Kind Code:
A1
Abstract:
The present invention is provided with a variable port (16), the aperture area of which and the initial discharge timing of which can be changed by the movement of a slide valve (12), and a fixed port (17), the aperture area of which does not change when the slide valve (12) moves. When the slide valve (12) is positioned the farthest to the intake side, the shape of the intake-side end surface of a discharge port aperture part substantially forms the shape of a letter 'Z', the angles of which are formed by connecting a slanted surface (12d) on the variable port (16) side, a slide surface (16l), which is the boundary between the fixed port (17) and the variable port (16), and a slanted surface (17a) on the fixed port (17) side.
