Vibrating compressor

A vibrating compressor comprising:

• a housing having an inner tube and an outer tube formed concentrically, said inner tube being connected with said outer tube via an end plate, said end plate being disposed at one axial end of said inner tube and said outer tube to form a housing closed end and a housing open end;
• a permanent magnet fixedly fitted to an inner circumferential surface of said outer tube;
• a driving coil provided in a gap between said permanent magnet and said inner tube;
• a cylinder fitted to an inside of said inner tube;
• a hollow piston equipped with a valve and inserted into said cylinder;
• a bobbin with support springs, said hollow piston being connected to said driving coil via said bobbin and supported by said support springs in such a manner as to perform reciprocating motion;
• a cylinder head connected to said housing to form a compression chamber at an end of said cylinder on a side into which said hollow piston is not inserted, whereby compressed fluid is discharged from said compression chamber by the reciprocating motion of said piston;
• a first cover plate disposed on said housing open end of said outer tube for closing said open end;
• a second cover plate disposed on said housing closed end, whereby a sealed container is formed by said outer tube, said first cover plate and said second cover plate to serve as an outer wall of the vibrating compressor;
• weld connection means for fixedly fitting said first cover plate and said second cover plate to said outer tube in an airtight state.
