Definitions
- the compression mechanism (120) includes a cylinder (121) having an annular cylinder chamber (CI, C2), and an annular piston (122) arranged in the cylinder chamber (CI, C2). I have.
- the cylinder (121) includes an outer cylinder (124) and an inner cylinder (125) arranged concentrically with each other, and the cylinder chamber (CI, C2) is provided between the outer cylinder (124) and the inner cylinder (125). ) Is formed.
- the suction gas is sucked into the compression mechanism (20) after the suction pipe (14) also flows into the low-pressure space (S1) in the casing (10).
- the gas sucked into the compression mechanism (20) is compressed by the compression mechanism (20) to a high pressure, flows out into the high-pressure space (S2) in the casing (10), and then is discharged into the discharge pipe (15). Is done.
- the discharge space (49) is formed between the upper housing (16) and the cover plate (18).
- a discharge passage (49a) is formed in the upper housing (16) and the lower housing (17) to communicate from the discharge space (49) to a space (high-pressure space (S2)) below the lower housing (17). .
- the second modified example is a joint structure of the body (11) and the upper end plate (12) in the casing (10).
- This is an example in which the structure is changed from the example in FIG.
- the upper end of the body (11) is formed to project slightly upward from the lower housing (17), and the lower housing (17) is joined to the body (11) by welding.
- the upper housing (16) has a smaller diameter than the inner diameter of the upper end plate (12) and is fixed to the lower housing (17).
- the upper end plate (12) is joined to the body (11) by welding at the upper end of the body (11).
- the discharge ports (45, 46) are provided in the lower housing (17). And the outer cylinder chamber
- the suction pipe (14) is not directly connected to the low-pressure chamber (suction chamber) (C-Lp) of the compressor mechanism (20). Since the inner end of the suction pipe (14) is opened in the low-pressure space (S1), the low-pressure space (S1) serves as a buffer space for sucking the suction gas into the compressor mechanism (20). It becomes. Therefore, the pressure pulsation generated in the suction stroke in the cylinder chamber (C) does not propagate through the suction pipe (14) into the refrigerant circuit system. The generation of sound can be prevented. Also, pressure pulsation on the discharge side can be prevented in the same manner, and performance deterioration due to suction overheating loss can be prevented.
