Claims

[Scope of utility model registration request]

(1) An unloader is provided at the cylinder intake port, a check valve is provided at the discharge port, and a receiver tank connected to the cylinder via the check valve is connected via piping to circulate and supply lubricating oil into the cylinder. At the same time, in the action direction of the compressed gas discharged from the discharge port, there is an electromagnetic force in the partition plate provided in the receiver tank and/or in the piping connecting the oil reservoir of the separator and the cylinder at a position after passing through the separator. An oil-cooled rotary compressor, comprising a valve, and the solenoid valve is configured to be opened at the same time as the compressor is stopped.

(2) An unloader is provided at the cylinder intake port, a check valve is provided at the discharge port, and a receiver tank connected to the cylinder via the check valve is connected via piping so that lubricating oil is circulated and supplied into the cylinder; The inside of the discharge port is connected to a receiver tank via a pump, and the compressed gas and lubricating oil in the discharge port are collected to the receiver tank, and the direction of action of the compressed gas discharged from the discharge port is recorded. A solenoid valve is provided in the partition plate provided in the receiver tank and/or in the piping that connects the oil sump of the separator and the cylinder at a position after passing through the separator, and the solenoid valve is opened at the same time as the compressor is stopped. An oil-cooled rotary compressor according to claim 1, characterized in that it is configured as follows.

(3) The unloader is provided with a solenoid valve, the solenoid valve is connected to a pressure switch that is activated by detecting the internal pressure of the receiver tank, and the solenoid valve and the first solenoid valve are of a type that closes when energized; The first solenoid valve is connected to the B contact of the pressure switch, and the first solenoid valve is connected to the A contact of the pressure switch, so that when the receiver tank internal pressure is above a certain value, the solenoid valve of the unloader is activated by the operation of the pressure switch. De-energize and open the solenoid valve to close the unloader, energize the first solenoid valve to close the solenoid valve, and then open the compressor stop switch at the time of stop to close the first solenoid valve. An oil-cooled rotary compressor according to claim 1 or 2, characterized in that the compressor is opened.
