PURPOSE: To prevent refregerant gas from leaking in order to improve the silencing ability by integrally shaping a U-shaped communicating pipe with one of two components into which a silencer is divided by an intersecting plane of the communicating pipe with the axis of the silencer so as to free the communicating pipe of seam.
CONSTITUTION: A separated type sucking silencer 14 which is shaped out of synthetic resin integrally with an approximately U-shaped communicating pipe 15 engaged in the opening of a head plate 11 so as to make direct communication with the interior of a cylinder 9 is divided into two bodies 14a and 14b by the intersecting plane of the U-shaped communicating pipe 15 with the axis of the silencer, that is, is composed of those bodies 14a and 14b. The body 14a is integrally provided with the U-shaped communicating pipe 15 and an engaging part 17 adapted for mounting the pipe to a cylinder 9. The bodies 14a and 14b are engaged with each other at respective openings 24 and 30 and then joined with bond, with a partition plate 27 interposed therebetween to form a resonant silencing chamber 32 inside the body 14b. Due to the freedom from seam which was produced when the communicating pipe 15 was inserted in the cylinder 9, as conventional, cooling gas may be prevented from leaking from the communicating pipe 15, hence improving the silencing ability.
