Problems solved by technology

[0005] However, when the compressed working fluid is discharged into the discharge valve housing chamber 515 through the discharge port, the oil contained in the working fluid adheres to the inner surface of the discharge valve housing chamber 515, and as a result, the oil stays in the shell of the discharge valve housing chamber 515. lower part of part 57
Since the remaining oil has not been used for the lubrication of the compressor, it is necessary to predict the amount of oil remaining in the lower part of the shell member 57 in advance, and to seal additional oil to offset this amount, so there is a risk of increased cost. bad condition
[0006] In addition, in order to reduce the pulsation of the vane compressor, it is required to reduce the pressure pulsation in the discharge path in the compressor, but if this is realized by a separate component, the number of components will increase, and the sealing part will be damaged. increase

Embodiment 1

[0028] exist Figure 1 to Figure 3 In , it represents a vane-type compressor suitable for a refrigeration cycle using a refrigerant as a working fluid. This vane type compressor 1 has a cylinder 8a constituting a compression chamber 19, a rotor 4 accommodated rotatably in the cylinder 8a, fixed to the drive shaft 3, and inserted into a plurality of vane grooves 5 provided in the rotor 4. The vane 6, the rear block 8b fixed to the rear end surface of the cylinder 8a, and the shell member 9 surrounding the front end surface and outer peripheral surface of the cylinder 8a and fitted to the rear block 8b are constituted.

[0029] The rear block 8b is integrally formed continuously on the rear side of the cylinder 8a housing the rotor 4, and constitutes the fixing member 8 that forms the compression chamber 19 together with the cylinder 8a.

[0030] The case member 9 is constituted by integrating a front block 9a abutting on the front end surface of the cylinder 8a, and a cylindri...

Embodiment 2

[0048] In addition, in Embodiment 1, an example of applying to a vane type compressor in which the discharge port 23 of the cylinder 8a is provided at one location along the circumferential direction is shown, but it can also be applied to a discharge port provided at two locations along the circumferential direction. 23 in the conventional vane compressor. Specifically, as Figure 4 As shown, in the cylinder 8a, discharge ports 23a, 23b are provided at symmetrical positions with respect to the drive shaft 3, and a partition wall 25 separating the discharge space 15 is provided between one of the discharge ports 23a and the through hole 26. Between one discharge port 23a and the other discharge port 23b, two protrusions 8aa abutting on the inner surface of the cylindrical portion 9b are provided, and between the other discharge port 23b and the through hole 26, there is a protrusion 8aa abutting on the inner surface of the cylindrical portion 9b. One convex portion 8aa on the...

Abstract

The invention provides a blade-type compressor, wherein oil is prevented from accumulating in the lower part of the casing of the compressor and the pulsation is lowered.The vane-type compressor (1) comprises a fixed part (8) equipped with a cylinder (8a), a rotor (4), blades (6) arranged on the rotor (4) and a casing part (9) surrounding at least the opening end and the outer circumferential surface of the cylinder (8a).A compression chamber (19) divided by the blades (6) is arranged between the inner circumferential surface of the cylinder (8a) and the outer circumferential surface of the rotor (4).A disgorging space (15) arranged between the outer circumferential surface of the cylinder (8a) and the inner circumferential surface of the casing part (9) communicates with the compression chamber (19) via a disgorging port (23).The motion fluid disgorged in the disgorging space (15) is guided toward the disgorging outlet (11) via the through hole (26) of the flange part (8d) arranged on the cylinder (8a).The motion fluid disgorged in the disgorging space (15) via the disgorging port (23) flows through the lower part of the cylinder (8a) and is guided toward the through hole (26).

Description

technical field [0001] The present invention relates to a vane compressor, and more particularly to a vane compressor that prevents oil from accumulating in the lower portion of the space between a cylinder rotatably accommodating a rotor and a shell member surrounding it. Background technique [0002] As a vane type compressor provided with a shell member surrounding the periphery of a cylinder, for example, a configuration shown in Patent Document 1 below is known. This vane type compressor includes a rotor fixed to a drive shaft and rotatably housed in a cam ring (cylinder), vanes inserted into a plurality of vane grooves provided on the rotor, and disposed on one end side of the cam ring. The side member and the shell member surrounding the other end side and the outer peripheral surface of the cam ring, the drive shaft is pivotally supported on the side member and the shell member, and on one of the side member and the shell member, There is provided a high-pressure ch...
