Claims

[Scope of utility model registration request]

The compressor is driven by an electric motor, and outside air is supplied to the compressor main body from an inhaler, lubricating oil is supplied to the compressor main body through an oil supply pipe by air pressure from an oil separator tank, and a sub-wire is supplied from the pressure section main body through a discharge pipe. Air and used lubricating oil are led to the oil separator tank, and only the lubricating oil is circulated between the compressor body and the oil separator tank to cool, lubricate, and seal the compressor body, and the compressed air is transferred to the oil separator tank. In an oil supply control position of an oil-cooled rotary compressor that is supplied from a separator tank to other parts, one solenoid valve or two solenoid valves controlled by a timer are provided in parallel in the oil supply pipe, One of the bypass oil supply pipes equipped with two solenoid valves is equipped with a restriction, and at startup, the supply of lubricating oil to the compressor body is stopped for a certain period of time set by the timer, or the supply of lubricating oil to the compressor body is stopped. An oil supply control device for an oil-cooled rotary compressor, characterized in that the supply amount is kept below a normal state, and after a certain period of time, the solenoid valve is opened to supply lubricating oil in a normal state. .
