<p>PROBLEM TO BE SOLVED: To provide a reciprocate compressor in which a piston rod can be positioned as preset and sealability of a liquid seal can be improved while preventing increase in accuracy required in parts processing and assembling.SOLUTION: A reciprocate compressor includes: a piston 23 which slides in a reciprocate manner in a cylinder 22; a cross head 33 which slides in a reciprocate manner in a gide cylinder 32; and a piston rod 31 having one end connected to the piston and the other end connected to the cross head. A liquid seal 54 is provided on a block 51 through which the piston rod penetrates. At least one of a connecting part of the piston and the piston rod and a connecting part of the piston rod and the cross head is connected slidably in a range of minute distance and swingably in a range on inure angle in a direction orthogonal to an axis of the members to be connected.</p> |
