(54) | RECIPROCATING COMPRESSION APPARATUS |
(57) To simplify a configuration for returning to uncompressed gas a lubricant separated
from gas discharged from a compression chamber, while effectively using the lubricant
, a reciprocating compression apparatus includes: a cylinder; a piston disposed in
the cylinder to form a compression chamber therein; a drive section for generating
drive force for reciprocating the piston in the cylinder; a separator for separating
a lubricant from gas discharged from the compression chamber; and a return line for
returning the lubricant separated in the separator to a return destination where gas
containing the lubrication is present and a pressure is lower than that in the separator.
The return line includes a lubrication cooling unit for cooling the lubricant flowing
through the return line and a drive section cooling section for cooling the drive
section with the lubricant which has been cooled in the lubricant cooling unit 35.
