<P>PROBLEM TO BE SOLVED: To prevent the mixture of a fine foreign matter from an oil supply mechanism of a hermetic compressor by a simple constitution so as to improve the reliability of the compressor. <P>SOLUTION: In such a constitution that a mesh filter 207 is put inside an inlet (caulked type) 208 to prevent the mixture of the foreign matter into a compressor mechanism 102, the mesh filter 207 is nipped in the caulking part provided at the inlet 208 and thereafter it is fixed by laser welding to a lid plate. Thus, a step of brazing the mesh filter 207 can be eliminated. In addition, the attachment of the mesh filter 207 takes place by a nipping method, whereby a stainless steel mesh filter 207 can be also attached, and thus an extremely fine mesh can be constituted. <P>COPYRIGHT: (C)2012,JPO&INPIT |
