Abstract
A reciprocating compressor 1A includes a compression part 2 compressing, by a piston 6, gas sucked into a cylinder 4 through a suction valve 36, and discharging the compressed gas through a discharge valve 51, a piston drive part 3 supplying a force to the piston 6 to reciprocate the piston 6 via a piston rod 9 coupled to the piston 6, and a housing 17 accommodating the compression part 2 and forming a vacuum region around the compression part 2.
Claims9
A reciprocating compressor comprising:
- a compression part compressing, by a piston, gas sucked into a cylinder through a suction valve, and discharging the compressed gas through a discharge valve;
- a piston drive part supplying a force to the piston to reciprocate the piston via a rod coupled to the piston;
- and
- a container part accommodating the compression part and forming a vacuum region around the compression part,
- further comprising an intermediate tube part disposed between the piston drive part and the container part, and accommodating the rod,
- wherein the intermediate tube part forms a first intermediate chamber, a second intermediate chamber, and a third intermediate chamber,
- the first intermediate chamber, the second intermediate chamber, and the third intermediate chamber are disposed in the order of the first intermediate chamber, the second intermediate chamber, and the third intermediate chamber in a direction from the piston drive part toward the container part,
- the first intermediate chamber is filled with a type of gas different from the gas sucked into the cylinder, and
- the third intermediate chamber is filled with a type of gas identical to the gas sucked into the cylinder.
