COMPRESSOR
Document Type and Number:
Japanese Patent JP2018112118
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a compressor capable of suppressing an increase in the dead volume of a compression chamber.SOLUTION: A compressor 1 incudes a housing 10 formed with a cylinder 160, and a piston 60 stored inside the cylinder 160 in a reciprocating manner and having a head part 61 opposed to a valve plate part 18 as part of the bottom of the cylinder 160, the head part 61 being formed with a communication path 610 communicating a compression chamber 100 formed between the valve plate 18 and itself and a suction chamber 600 formed inside the piston 60, the piston 60 being provided with a spool 90 which is constructed to be movable in a stroke direction as a direction in which the piston 60 reciprocates, the spool 60 including a valve element part 91 for opening/closing the communication path 610, and a stopper part 92 connected to the valve element part 91 for specifying the maximum displacement amount in the opening direction of the valve element part 91, the stopper part 92 being arranged on the side of the suction chamber 600.SELECTED DRAWING: Figure 1
