Title:
ROLLING CYLINDER TYPE DISPLACEMENT COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2016/067355
Kind Code:
A1
Abstract:
A rolling cylinder type displacement compressor according to the present invention is provided with a rotary drive source, a compression unit, and an oil storage unit. The compression unit includes a rolling cylinder (1) having a cylinder groove, a circling piston (3) slidably accommodated in the cylinder groove, and a stationary cylinder (2) having an eccentric cylinder hole in which the rolling cylinder is rotatably accommodated. To the eccentric cylinder hole of the stationary cylinder, a fixed pin (5) having a center line different from a shaft axis is attached. The circling piston has a slide groove (3b). The fixed pin has such a configuration as to be slidably fitted to the slide groove, and is configured in such a manner that the autorotation of the circling piston and the rotation of the rolling cylinder are synchronized. Lubricating oil in the oil storage unit is supplied to the fixed pin and the slide groove. As a result, in the case where a pin mechanism is applied to the rolling cylinder type displacement compressor, the lubricating oil can be sufficiently supplied to the pin mechanism, so reliability of the pin mechanism can be improved.
