no. 1 Embodiment

[0086] Next, a first embodiment of the present invention will be described in detail with reference to the drawings.

[0087] The scroll compressor (1) of the first embodiment compresses low-pressure refrigerant sucked in from the evaporator and discharges it to the condenser, for example, in a refrigerant circuit performing a vapor compression refrigeration cycle in an air conditioner or the like. The scroll type compression (1) as figure 1 As shown, inside the housing (10), a compression mechanism (20) and a drive mechanism (30) for driving the compression mechanism (20) are provided. The compression mechanism (20) is arranged in the upper part of the casing (10), and the driving mechanism (30) is arranged in the lower part of the casing (10).

[0088] The housing (10) is composed of a cylindrical tube (11) and disc-shaped end plates (12, 13) fixed to the upper and lower ends of the tube (11). The upper end plate (12) is fixed to a frame (23) described later, and the fram...

no. 2 Embodiment

[0121] Below, refer to Figure 8 A second embodiment of the present invention will be described.

[0122] The scroll compressor (1) of the second embodiment is different from the first embodiment in the structure of the high-pressure oil introduction passage (44), and the other parts are the same as the first embodiment. Figure 8 This is an enlarged view showing the structure of the high-pressure oil introduction passage (44) and its peripheral portion.

[0123] The high-pressure oil introduction passage (44) of the scroll compressor (1) is formed at the end of the fixed scroll (21) in order to introduce the high-pressure oil in the second space (S2) as in the first embodiment. An annular oil groove (43) under the plate (21a), the high-pressure oil introduction passage (44) is formed on the fixed scroll (21) and the frame (23). The high-pressure oil introduction valve (45) in the first embodiment is not provided.

[0124] The high-pressure oil introduction passage (44) is ...

Abstract

The scroll compressor of the present invention is equipped with a fixed scroll (21) fixed in the housing (10), a movable scroll (22) engaged with the fixed scroll (21), and a movable scroll (22) Pushing mechanism (40) pushed on the fixed scroll (21). Using the pressure of the high pressure space (S2) acting on the back side of the movable scroll (22), the pressing force of the movable scroll (22) against the fixed scroll (21) is obtained, and the compression ratio changes due to operating conditions , to adjust the pushing force.

Description

technical field [0001] The present invention relates to a scroll-type compressor, and more particularly, to a compressor that prevents a reduction in operating efficiency. Background technique [0002] A compressor that compresses a refrigerant in a refrigeration cycle includes, for example, a scroll compressor disclosed in Japanese Patent Application Laid-Open No. 5-312156 and the like. The scroll compressor includes a fixed scroll and a movable scroll in a casing, and the fixed scroll and the movable scroll have scroll plates that mesh with each other. The fixed scroll is fixed on the casing, and the movable scroll is connected to the eccentric shaft portion of the drive shaft. The movable scroll cannot rotate relative to the fixed scroll, but only revolves, so that the compression chamber formed between the two scroll plates compresses and compresses the refrigerant. [0003] like Figure 14 As shown, when compressing the refrigerant, a thrust load PS, which is an axial...
