Abstract

PURPOSE:To reduce a minute gap generated in an abutting surface and to obtain the multiple cylinders rotary compressor having no gas leakage and high reliability by a method wherein divided intermediate partitioning plates are fixed by bolts, nuts and the like and, further, are fixed by means of fusion welding. CONSTITUTION:The intermediate partitioning plates 15, 20 are divided into two parts, and assembled at the position of about 90 degrees with respect to the positions of vanes 5, 6 and are pinchingly fixed between cylinders 10, 11 through tightening parts 16, 17, 18, 19 such as bolts, nuts and the like. The cylinder 10 is fixed to a side housing 9 through bolts 19 while the side housing 12 is fixed to the cylinder 11 through bolts 18. Holes 21a, 21b, 21c are bored on the intermediate partitioning plate 15 while the holes 22a, 22b for tightening are bored on the intermediate partitioning plate 20. In order to restrict the munute gaps (a), (b) produced at the abutting surface of the intermediate partitioning plates 15, 20, one ends (c), (d) of the abutting part of the intermediate partitioning plates 15, 16 are fixed by welding or the like to achieve the desired purpose.
