Abstract:
An electromagnetic compressor capable of reciprocating a piston to suck in and compress a gas by means of the force of attraction of an electromagnet and the resilient force of a return spring, comprising:a cylinder assembly including a front cylinder portion, a rear cylinder portion, and a center hole capable of storing said piston for reciprocation and having a working chamber defined by the piston; an electromagnet located between said front cylinder portion and the rear cylinder portion and capable of actuating said piston; an electrically conductive member for supplying electricity to the electromagnet; and an internal passage connecting said working chamber to the outside of the compressor, said cylinder assembly and the electromagnet having an integral structure molded from a resin in a manner such that said internal passage is hermetically sealed with respect to the electromagnet and the electrically conductive member.
