る。(B) Prior art It is generally known that a separate suction muffler in a refrigerant compressor is preferably made of synthetic resin, which has heat insulating properties and is lightweight, in order to prevent heating of the refrigerant gas flowing into the muffler. However, in this synthetic resin separate suction silencer,
The communication pipe that guides the refrigerant gas in the muffler into the cylinder is formed into a U-shape because of the arrangement of the components of the compressor, so that the muffler can be housed more concisely. There was a strong desire to develop a suction muffler in which the communication pipe was integrally molded from synthetic resin. Here, in the manufacturing method of a suction muffler in which a U-shaped communicating pipe is integrally molded with synthetic resin, the simplest cutting die method is to divide the communicating pipe into two parts at a flat part that includes the axis line, and separate each vessel body. This is a method of combining. however,
According to the above method, there is a problem in that the U-shaped communication pipe has a seam in its axial direction, and when this communication pipe is inserted into the cylinder, refrigerant gas leaks from the seam, impairing the function of the suction muffler. (/Sai) Summary of the Invention The present invention has been made in view of the above-mentioned points.A separate type suction muffler made of synthetic resin is divided into two on a plane intersecting the axis of a U-shaped communication pipe. The above-mentioned drawbacks are solved by configuring the first and second vessel bodies as well as integrally molding the communicating bone on either one of the first and second vessel bodies.

ある。Therefore, the separate type suction muffler (14) made of synthetic resin is
First, the first vessel body is divided into two along a plane intersecting the axis of the letter-shaped communication tube (15) and is composed of a first vessel body (14a) and a second vessel body (14b). (14a) has a U-shaped communication pipe α9, a locking part (17) for attachment to the cylinder (9), and a flange part a8).
The oil fence (2)l) is integrally molded. And (2]) is (33) of the jig pin C(3)G44)C3 for forming the communicating pipe 05) as shown in FIG.
is an insertion hole into which is inserted, and this insertion hole (21) is closed with a camp (221). (23) is a stepped portion provided at the opening (24) of this first vessel body (14a). There is a separate resonant silencing chamber (3) in this stepped portion 123).
A partition plate (27) having a communication hole (05) for seal molding and an oil hole (26) for discharging oil accumulated in the resonance muffling chamber C32 is positioned. As shown in FIG. 5, this oil hole (z6) maintains the volume of the resonant silencing chamber and maintains the silencing effect. On the other hand, the second vessel (14b) includes an oil fence (28), 091
It is shaped like a single P. The opening (30) of the second vessel (14b) has a double wall structure, and the opening (24) of the first vessel (14a) is located in the groove between the double walls.
At the same time, the inner wall 01) of the double wall supports and fixes the partition plate (27) positioned in the step groove (23) of the first container body (14a,). In addition, as shown in FIG. 6, the suction tail pipe (11) is formed by cutting its opening (19a) diagonally so that it is parallel to the opening (16a) of the suction pipe (Ifil), so that the refrigerant flow The distance between the opening (19a) of the suction tail pipe (19) and the opening (16a) of the suction pipe (161) is made sufficiently short to improve the suction capacity of the suction muffler θ4. Here, the distance l between the suction tail pipe Ogl and the sealed case (2) is long enough to prevent resonance of the suction pulsation sound, and the suction pipe (16
) into the sealed case (2) is the protruding length 12 of the electric element (
4) The structure is designed to be sufficiently short to prevent collisions. A separate type suction muffler 04) made of synthetic resin is made by fitting the first container body (14a) and the second container body (14b) as described above at their respective openings (24) <301. , and a resonant silencing chamber (321
It is constructed by molding and bonding together with an adhesive or the like.

The refrigerant gas that has flowed into the sealed case (2) through the suction pipe (16) is passed through a so-called semi-direct suction system in which the suction tail pipe (19a) is located close to the opening (16a) of the suction pipe (16). The refrigerant gas at a relatively low temperature is sucked into the suction muffler α4). The refrigerant gas sucked from the suction tail pipe Q9) is transferred to the first body (14a).
It directly flows into the cylinder (9) from the U-shaped communication pipe 05) fitted on the head plate 01), but at this time, the partition plate (27) separates the container body (14b) from @2.
) The sound is muffled by a resonant muffler chamber 02 formed in the above. In addition, the oil fence CI is integrally formed on each vessel (14a) (14b)! 01 t281 (29
+ indicates that the lubricating oil (6), which is sprayed from the jet hole (3a) at the upper end of the rotating shaft (3) to cool the compression element (5), is transmitted through the motor case (7) to the suction muffler (14). This is to prevent oil from being sucked in from the suction tail pipe, and to reduce the volume of oil discharged. Furthermore, the flange 08) provided on the suction tail pipe 09) absorbs lubricating oil (6) that is sprayed from the jet hole (3a) at the upper end of the rotating shaft (3).
This prevents the lubricating oil (6) from being sucked into the suction tail pipe along the main body of the suction muffler (04), and drips lubricating oil (6) onto the bottom of the sealed case (2).

Since the communication pipe is integrally molded on one side of the first and second containers, there is no seam in the communication pipe as in the conventional case, and the refrigerant gas is allowed to flow from the communication pipe. It is possible to form a U-shaped communication pipe that can prevent the leakage of the air and allow the separation-type suction muffler to be stored in the most compact manner in view of the arrangement of each component of the compressor.
