<p>PURPOSE:To simplify the internal shape of a compressor by spraying the circulating oil in a refrigerating cycle direction to sliding sections by use of a suction action of the compressor so as to lubricate the sliding sections. CONSTITUTION:The refrigerant gas entered through a suction port 18 is separated into a refrigerant and oil by means of the difference between inertia forces of the refrigerant and the oil when turned through a low pressure gas passage 20, and the oil is fed into a small sump 30'. A pipe 31 is connected from this sump 30' to the low pressure gas passage 20, and a small hole 32 is provided on said pipe downstream the flow of the refrigerant. When the refrigerant gas flows through the low pressure gas passage 20, the vicinity of the small hole 32 of the pipe 31 becomes a negative pressure, sucking oil from the pump 30' in a form of mist, which, together with the refrigerant gas is sucked into a crank case so as to be sprayed to various sliding sections for lubrication.</p> |
