Piston for a reciprocating compressor
 A piston/cylinder assembly for a reciprocating compressor has a piston comprising telescopingly connected first and second piston members. The first piston member is connected to a connecting rod. The second piston member is provided with a piston head and is connected to the first piston member in such a way as to be movable axially relative to the first piston member by a predetermined distance. A spring is interposed between the first piston member and the second piston member to yieldably urge the first and second piston members axially apart.
