Title:
POROUS PART FOR REFRIGERATORS, AND METHOD OF PRODUCING THE SAME AND REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2001/042656
Kind Code:
A1
Abstract:
In this porous part producing method, head parts (11A, 11B), which are sintered parts, in the interior of a compressor are subjected at least to vacuum substitution or heat blow cleaning, whereby oils, such as rust-preventive oil in the head parts (11A, 11B) in the interior of the compressor, forming a cause of contamination or sludge, is discharged from the head parts (11A, 11B) in the interior of the compressor, whereupon the head parts (11A, 11B) in the interior of the compressor are immersed in alkyl benzene type oil serving as refrigerator oil. Thereby, the deterioration-inducing substances in the head parts (11A, 11B) in the interior of the compressor can be replaced by the refrigerator oil; thus, it is possible to produce a porous part for refrigerators which will not bring about contamination or sludge even if used as a component for refrigerators for a long time.
