<P>PROBLEM TO BE SOLVED: To efficiently replace a seal ring, in a compressor provided with the seal ring and an intake flap valve on a piston head. <P>SOLUTION: This compressor X includes a housing 1, the piston head 23, an eccentric shaft 22 turning by a motor, and a piston rod 21 for transmitting turning of the eccentric shaft 22 to reciprocating motion of the piston head 23. A space in the housing 1 is separated into an intake chamber 1A and a compression space 1B with the piston head 23 as a boundary, and the piston head 23 has a first part 231 connected to the piston rod 21, a second part 232 detachably installed in the first part 231, a seal ring 233, a ventilation passage 234 for communicating the intake chamber 1A with the compression space 1B and the flap valve 235 arranged on one end of the ventilation passage 234. The seal ring 233 is sandwiched by the first part 231 and the second part 232, and the flap valve 235 is arranged in the second part 232. <P>COPYRIGHT: (C)2013,JPO&INPIT |
