PURPOSE:To prevent the bubbling of the oil stored in an oil reservoir by mounting a lower cap on the body lower end of a sealed vessel through a dashboard having recessed and protruded parts on the rising part of its outer circumferential part and having notches accorded with the recessed parts on its collar part. CONSTITUTION:A lower cap 16 is welded to the lower end of a closed vessel having a scroll type compressor part 2 disposed in the upper part and an electric motor 3 in the lower part through the collar 18a of a dashboard 18. The dashboard 18 is formed by integrally providing a flat plate part 18b, a rising part 18c having recessed and protruded parts, and the collar 18a nearly accorded with the rising part, and has such a constitution as forming a plurality of passages by the recessed parts and the inner wall of the closed vessel 1 by press-fitting the protruded parts to the inner wall of the closed vessel 1. When a part of the oil contained in a refrigerant gas introduced to the upper part of the electric motor 3 through a passage 1a is separated from the refrigerant gas, this oil is fallen into the electric motor 3 lower part and stored in an oil reservoir through the outer circumferential passages of the dashboard 18. |
