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

[0064] figure 1 A longitudinal sectional side view of a compressor C showing a first embodiment of the present invention, figure 2 represents another longitudinal profile, image 3 A perspective view showing a compression element 3 of a compressor C, Figure 4 Another perspective view showing the compression element 3 of the compressor C, Figure 5 A top view showing the compression element 3 of the compressor C, Figure 6 A bottom view showing 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.

[0065] 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...

Embodiment 2

[0112] 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.

[0113] Here, Figure 30 and Figure 31 It is an example of the compressor C at this time, and Fig. 30 shows a longitudinal sectional side view of the rotating shaft 5 and the compression element 3, Figure 31 It is a perspective view showing the rotating shaft 5 in a state where the air cylinder 8 is attached. Figure 30 and Figure 31 As shown, for the sub-bearing 23 on the lower side (the other side) side of the compression member 9, it becomes the bearing on the o...

Embodiment 3

[0118] Below, refer to Figure 32 ~ Figure 34 A third embodiment of the present invention will be described.

[0119] Figure 32 is a longitudinal sectional side view of the compressor C at this time, Figure 33 is another longitudinal sectional side view of compressor C, Figure 34 It is yet another longitudinal sectional side view of the compressor C. In addition, in Figure 32 ~ Figure 34 , appended with the above Figure 1 to Figure 31 Components with the same symbols as shown in the components have the same or similar effects.

[0120] 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 .

[0121] 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...

Abstract

An object is to provide a highly efficient compressor at a low cost while reducing sliding losses of a vane and inhibiting a leakage from the vane and a compression member to improve a workability of the vane. The compressor comprises: the compression member whose upper surface (one surface) crossing an axial direction of a rotary shaft is inclined continuously between a top dead center and a bottom dead center and which is disposed in a cylinder to be rotated by the rotary shaft and which compresses a fluid sucked from a suction port to discharge the fluid via a discharge port; and a vane which is disposed between the suction port and the discharge port to abut on the upper surface (one surface) of the compression member and which partitions a compression space in the cylinder into a low pressure chamber and a high pressure chamber, and the upper surface of the compression member comprises: a flat surface constituted in a predetermined region centering on an intermediate point between the top dead center and the bottom dead center; and curved surfaces gradually approaching the top dead center and the bottom dead center continuously from the flat surface.

Description

[0001] This application is a divisional application of the application with the title of invention "compressor" and application number 200510107130.6 filed by Sanyo Electric Co., Ltd. on September 28, 2005. technical field [0002] The present invention relates to a compressor for compressing and discharging fluids such as refrigerant and air. Background technique [0003] 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. [0004] 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, alt...
