旋转式压缩机
摘要：
本发明提供一种旋转式压缩机，形成从活塞(32)的内面(32b)与圆筒形的嵌合部(32a)连通的供油孔(60)，使得油槽(45)根据曲轴(31)的旋转按照一定的区间与该供油孔(60)连通，油槽(45)中的油液通过供油孔(60)，被供给到由圆筒形的嵌合部(32a)和滑叶(33)前端的插入部(33a)形成的摆动部，这样，摆动部的滑动状态变得更好，摆动部的密封性也得以提高，能够进一步抑制气体通过摆动部的缝隙从高压的压缩室(39)向低压的吸入室泄漏。
摘要（英）：

The invention provides a rotary compressor. An oil supply hole (60) connecting from the inner surface (32b) of a piston (32) to a cylindrical fitting section (32a) is formed. This causes a predetermined zone of an oil groove (45) to communicate with the oil supply hole (60) when a crankshaft (31) is rotated and allows oil which is present in the oil groove (45) to pass through the oil supply hole (60) and be supplied to a rocking section formed by the cylindrical fitting section (32a) and an insertion section (33a) at the tip of a vane (33). As a result, sliding conditions of the rocking section are further improved and sealing properties of the rocking section are also improved. This further suppresses a leakage of gas from a high-pressure compression chamber (39) to a low-pressure suction chamber through a gap of the rocking section.
