[0007] However, in the conventional compressor disclosed in the above-mentioned gazette, since its structure is to stop the drive motor when the exhaust gas temperature rises excessively, for example, the drive motor stops immediately during pump-down operation. There is a problem that it takes a long time until the pump-down operation is completed
Also, since the compressor starts and stops repeatedly, compressor reliability can be compromised

[0028] The scroll compressor of the first embodiment is a compressor for compressing refrigerant gas, and is connected to a refrigerant circuit not shown in the figure, which operates in a refrigeration cycle in which refrigerant gas circulates.
[0029] Such as figure 1 As shown, such a scroll compressor 10 has a casing 11 consisting of a sealed domed pressure vessel. Inside the casing 11, a compression mechanism 15 that compresses refrigerant gas, and a drive motor 16 that drives the compression mechanism 15 are accommodated. The drive motor 16 is arranged below the compression mechanism 15 and is connected to the compression mechanism 15 through a drive shaft 17 .
[0030] The compression mechanism 15 has a fixed scroll 21 and an orbiting scroll 22 . The two scrolls 21, 22 respectively have end plates 21a, 22a, and spiral scroll wraps 21b, 22b vertically provided on the end plates 21a, 22a. The scroll rings 21b, 22b of the above scroll disks 21, 22 are designed to be eng...

[0050] image 3 Shows the second embodiment of the present invention. In addition, in the second embodiment, the same structural elements as those of the first embodiment are assigned the same reference numerals, and detailed description thereof will be omitted.
[0051] In the second embodiment, unlike the first embodiment, the fixed scroll 21 is constructed by bonding the sub-part 21f to the main part 21d of the end plate 21a. That is, in the second embodiment, the recessed portion 21e for fitting the sub-part 21f is not provided on the main part 21d.
[0052] The subpart 21f is formed into a disc shape. Moreover, the lower surface of the sub-component 21f is bonded to the upper surface of the central portion of the main part 21d, that is, the surface on the opposite side to the scroll 21b, and even if thermally expanded, the main part 21d and the sub-component 21f are still bonded together. , there is no relative displacement between the two. That is, the main component...

Abstract
To continue operation of a scroll compressor without causing lubrication failure even in a state of heightening a delivery temperature to a certain degree. A recessed part 21e is formed in a central part of a back face positioned on the opposite side of a lap 21b in a main member 21d of an end plate 21a of a fixed scroll 21. An auxiliary member 21f is fitted in this recessed part 21e. The main member 21d is made of, for example, cast iron. The auxiliary member 21f is composed of, for example, copper and aluminum. A linear expansion coefficient becomes larger on the back face side than the front face side provided with the lap 21b in a central part of the end plate 21a. When the delivery temperature becomes high, the central part of the end plate 21a swells to the back face side, and clearance between the end plate 21a and the lap 22b can be secured.
Description
technical field [0001] The present invention relates to a scroll compressor, and in particular, to a scroll compressor in which measures are taken to prevent the interference of the scroll disk due to excessive discharge temperature. Background technique [0002] Conventionally, a scroll compressor has been used as a compressor for compressing refrigerant gas in a refrigeration cycle. This type of scroll compressor has a fixed scroll and an orbiting scroll within a casing. The two scrolls respectively have an end plate and a spiral scroll ring protruding from the end plate. The fixed scroll is fixed on the casing, and the orbiting scroll is connected to the eccentric part of the drive shaft and can revolve. The orbiting scroll does not rotate but only revolves while the scroll of the orbiting scroll meshes with the scroll of the fixed scroll. In this way, the compression chamber formed between the two scrolls can be continuously reduced to compress the gas in the compress...
