PURPOSE:To prevent delivered gas from leaking into a low pressure enclosed shell, by forming the point end of a delivery pipe, communicating with outside the low pressure enclosed shell, into conical shape and forcedly fitting said conical part to be engaged with a seal ring in the delivered gas opening part of a fixed scroll. CONSTITUTION:A compressor connects one end of a delivery pipe 23 penetrating a low pressure enclosed shell 10 with an external pipe while forms the other end into a tapered conical part 23a to be inserted to a fixed scroll delivery hole 3. The compressor, forming in the delivery hole 3 a stepped part 3a having a contour larger than the external diameter of the delivery pipe 23, mounts an elastic seal ring 24, forming its section into a rectangular shape, to be inserted into said stepped part 3a. The compressor, forcing the one end conical part 23a of the delivery pipe 23 to be fitted to the seal ring 24, provides good sealing to be performed by elastic deformation of the seal ring 24. |
