ける起動負荷軽減装置。 In an air compressor in which a compression piston in a compression cylinder is driven by a drive motor to compress the air in the compression cylinder and feed it into an air tank, a portion of the circumferential surface of the output shaft of the drive motor is provided. A magnet is disposed, and a rotation detection valve for the drive motor is provided, the valve stem having a tip disposed close to the side of the output shaft which is not affected by the magnetic force of the magnet when the rotation of the drive motor is stopped; Connect one side of the valve to the air tank,
The other end is connected via a throttle passage to an unload valve that releases the air inside the compressed cylinder to the atmosphere, and when the drive motor stops rotating, the rotation detection valve connects the air tank and the unload valve. 1. A start-up load reduction device for an air compressor, characterized in that air in a compression cylinder is released to the atmosphere by.
