Abstract

PURPOSE:To always ensure a suitable amount of lubrication oil by providing an auxiliary oil sump section in the bottom section of a compressor other than an oil sump, by forming passage communicating between the auxiliary oil sump and the intermediate pressure section and the discharge pressure section of the compressor, and by providing solenoid valves in the passages. CONSTITUTION:In a horizontal type scroll compressor, a rotary scroll which is held by the pressure in an intermediate pressure chamber is rotated relative to a stationary scroll 10 so as to decrease the volume of a closed working chamber 11. In this arrangement, when the level of oil in the scroll compressor 1 is lowered, an oil level detector 7 energizes a timer relay 8 having an (a) contact 8 which is closed so as to energize solenoid valves 6. Accordingly, the solenoid valves 6 open passage 4, 5, respectively. With this arrangement, oil is fed from an oil sump container 2 to the intermediate pressure chamber 3 through the passage 4. Thereafter, the timer relay 8 closes the solenoid valves 6 in order to prevent oil from being excessively fed.
