<p><P>PROBLEM TO BE SOLVED: To provide a piston type compressor improving heat insulation in a compression chamber. <P>SOLUTION: A hole 111 for formation of a compression chamber is formed on a cylinder 11, and a cylindrical heat insulating material 30 is press-fitted in the hole 111 for formation of the compression chamber. The heat insulating material 30 is made of synthetic resin. The inside of a cylinder of the heat insulating material 30 makes a cylinder bore 43, and an aluminum made piston 25 is stored in the cylinder bore 43. The piston 25 partitions the compression chamber 112 in the cylinder bore 43. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
