Hermetic rotary compressor |
摘要 |
A hermetic rotary compressor operates two cylinders simultaneously in the regular operation; however it halts operating one of the cylinders when it selects an operation with a half capacity. A vane room of the halted cylinder is air-tightly sealed with respect to lubricant atmosphere in a hermetic case. An oil-supplying groove is provided to a vane groove of the halted cylinder, and lubricant is supplied to the oil-supplying groove in order to lubricate the vane.
