VIBRATION TYPE COMPRESSOR AND STIRLING REFRIGERATING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a vibration type compressor capable of surely securing a state that a piston can be reciprocated without contacting with a cylinder, and to provide a Stirling refrigerating machine using the same.;SOLUTION: The vibration type compressor includes: a compressor body 10 formed with a cylinder; a piston 21 inserted into the cylinder 11 through a clearance and forming a compression space; a support spring supporting the piston freely to reciprocate; a drive source for reciprocating the piston; a piston drive support continuously connected to the support spring which is integrally formed with the piston, and the drive source; and a bottomed cylindrical pressure case 50 forming a gas chamber. The piston has: a tapered part wherein a radius is increased as it goes inward in the axial direction at an end at a compression space side thereof; and a buffer space in the axial direction at a predetermined distance from the axial inside end of the tapered part.;COPYRIGHT: (C)2010,JPO&INPIT
