Problems solved by technology

That is, with the inclination of the compression part, the radius of curvature forming the front end of the blade is small on the inner diameter side of the compression part and becomes larger toward the outer diameter side, resulting in difficulty in processing and an increase in the processing cost of the blade

Embodiment 1

[0063] Fig. 1 shows a longitudinal sectional side view of a compressor C of the first embodiment of the present invention, Fig. 2 shows another longitudinal sectional side view, Fig. 3 shows a perspective view of a compression element 3 of a compressor C, and Fig. 4 shows a compressor C Another perspective view of the compression element 3, FIG. 5 shows a top view of the compression element 3 of the compressor C, and FIG. 6 shows a bottom view of the compression element 3 of the compressor C. In each figure, 1 is an airtight container, and the driving element 2 is accommodated on the upper side in the airtight container 1, and the compression element 3 driven by the rotation shaft 5 of the driving element 2 is accommodated on the lower side.

[0064] The driving element 2 is a motor including: a stator 4 fixed to the inner wall of the airtight container 1 and wound with a stator coil; and a rotor 6 located inside the stator 4 and having a rotating shaft 5 in the center. In add...

Embodiment 2

[0111] In addition, in Embodiment 1, a shaft seal seal 50 is provided at the end of the main bearing 13 that is on the opposite side of the compression member 9 to prevent the refrigerant gas in the compression space 21 from passing between the rotating shaft 5 and the support member 7. The failure of the gap leakage of the main bearing 13 is at the end of the day, but it is not limited to this, and a piston ring type seal can also be provided on the rotating shaft 5 corresponding to the position of the bearing.

[0112] 30 and 31 are an example of the compressor C at this time. FIG. 30 shows a longitudinal sectional side view of the rotary shaft 5 and the compression element 3, and FIG. 31 shows a perspective view of the rotary shaft 5 with the cylinder 8 attached. As shown in FIGS. 30 and 31 , for the sub-bearing 23 on the lower side (the other side) of the compression member 9, it becomes the bearing on the opposite side of the compression member 9, that is, the bearing on t...

Embodiment 3

[0117] Hereinafter, a third embodiment of the present invention will be described with reference to FIGS. 32 to 34 .

[0118] 32 is a longitudinal sectional side view of the compressor C at this time, FIG. 33 is another longitudinal sectional side view of the compressor C, and FIG. 34 is still another longitudinal sectional side view of the compressor C. In addition, in Fig. 32 to Fig. 34, components having the same reference numerals as the components shown in Fig. 1 to Fig. 31 described above have the same or similar effects.

[0119] In the present embodiment, the compression element 3 is accommodated in the upper side and the driving element 2 is accommodated in the lower side in the airtight container 1 . That is, in this embodiment, the compression element 3 is arranged above the drive element 2 .

[0120] The driving element 2 is a motor, which is the same as the above-mentioned embodiment, and is composed of a stator 4 fixed to the inner wall of the airtight container...

Abstract

The invention provides a compressor which has low cost and high efficiency. The compressor can restrain the leakage between blades and a compression component while reducing the slippage loss of the blades, and can improve the working quality of the blades. The compressor comprises the compression component and the blades; wherein, the upper side (one side) which is axially crossed with a rotating shaft is continuous and slant between an upper dead center and a lower dead center; at the same time, the compression component is arranged in a cylinder and is driven by the rotating shaft to rotate, liquid sucked in from a suction port is compressed and is discharged from an exhaust port, and the blades which divide the compression space in the cylinder into a low pressure chamber and a high pressure chamber are arranged between the suction port and the exhaust port, and are contacted with the upper side (one side) of the compression component. The upper side of the compression component has a plane formed in a prescribed limit which takes an intermediate point between the upper dead center and the lower dead center as the center and a curved surface which is continuous from the plane and gradually closes to the upper dead center and the lower dead center.

Description

technical field [0001] The present invention relates to a compressor for compressing and discharging fluids such as refrigerant and air. Background technique [0002] Until now, for example, in refrigerators, a method in which a compressor compresses a refrigerant and circulates the refrigerant in a circuit is used. Examples of such compressors include a rotary compressor called a rotary compressor (JP-A-5-99172 (Document 1)), a scroll compressor, and a screw compressor. [0003] The above-mentioned rotary compressor has the advantages of relatively simple structure and low manufacturing cost, but has the problems of large vibration and torque fluctuation. In addition, scroll compressors and screw compressors have problems of difficulty in processing and high cost, although torque variation is small. [0004] Therefore, as shown in Japanese Patent Application Publication No. 2003-532008 (Document 2), a method of compressing fluid by dividing a compression space with vanes ...
