プ。In a reciprocating vacuum pump that uses a permanent magnet and an excitation coil as a driving source, a piston is disposed inside the outer cylinder and separated from the inner wall of the outer cylinder by a bellows, and a through hole communicating with the suction chamber is provided. A hollow space is formed in the thick part of the cylinder, and a hollow cylindrical body communicating with the hollow space is embedded in the excitation coil, and a cooling medium is sealed in the hollow space and the hollow cylinder, and the cooling medium is sealed around the drive source and outside the bellows. A noiseless vacuum pump characterized by creating a vacuum and eliminating sound propagation.
