Embodiment 1

[0107] figure 1 It is a longitudinal sectional side view showing an embodiment of a hermetic scroll compressor to which the present invention is applied, figure 2 express figure 1 A partial enlargement of the . In each figure, 1 is a sealed container. The airtight container 1 is composed of a vertically long cylindrical container body 1A, and substantially bowl-shaped end caps 1B and bottom caps 1C respectively welded and fixed to both ends (upper and lower ends) of the container body 1A.

[0108] Furthermore, a partition plate 10 for partitioning the space in the airtight container 1 up and down is provided above the inside of the airtight container 1 . That is, the inside of the airtight container 1 is divided into an upper space 11 and a lower space 12 by the partition plate 10 .

[0109] In the lower space 12 in the sealed space 1 , the compression element 2 is accommodated on the upper side, and the electric element 3 as a driving device for driving the compression e...

Embodiment 2

[0147] In addition, in the above-mentioned embodiment, the refrigerant in the compression process is introduced into the front space 96 of the thrust ring 72 through the communication hole 78 for introducing the refrigerant in the compression process into the back space 75 of the thrust ring 72, that is, the same The intermediate pressure is introduced into the front space 96 of the thrust ring 72 and the back space 75 of the thrust ring, but the present invention is not limited thereto, as long as the refrigerant in the compression process is introduced into the two spaces of the front space and the back space of the thrust ring, so that from The relationship between the force applied to the thrust ring from the front space of the thrust ring and the force F2 applied to the thrust ring from the back space satisfies F1<F2, which is effective for the present invention.

[0148] For example, if the relationship between the force F1 applied to the thrust ring from the front space ...

Abstract

The invention relates to a sealed type scroll compressor which decreases a sliding loss between a thrust ring and a orbit scroll and improves the efficiency of the sealed type scroll compressor while preventing the leakage of a refrigerant between a fixed scroll and the orbit scroll, and the compressor provides a relation of F1 < F2, in which F1 is an operating pressure applied from the front surface space of the thrust ring to the thrust ring, and F2 is an operating pressure applied from a back surface space to the thrust ring.

Description

technical field [0001] The present invention relates to a hermetic scroll compressor having a compression element having a fixed scroll and an oscillating scroll within a hermetic container. Background technique [0002] A conventional scroll compressor of this type includes: a compression element having a fixed scroll and an oscillating scroll in a hermetic container; and an electric element rotatably driving the oscillating scroll. In the fixed scroll, a spiral groove is formed by projecting a spiral lap on an end surface. The oscillating scroll also has a scroll-shaped lap portion protruding from the end surface. When the lap portion is placed in the groove of the fixed scroll, a plurality of laps are formed on the inner peripheral side and the outer peripheral side. compression chamber. [0003] Then, the orbiting scroll moves around the compression chamber by being rotationally driven, thereby reducing its volume and compressing the refrigerant. [0004] In such a sc...
