Problems solved by technology

[0005] However, when the two cylinders used in the single-cylinder rotary compressor are used, there is no room in the inner volume of the airtight container, and there are problems in terms of reliability due to the reduction of the amount of oil and the volume of the space.
In addition, when two cylinders are used to reduce the thickness of the above-mentioned cylinders, there is a problem that the power of the compressor is reduced.

Embodiment Construction

[0027] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The "screws" mentioned in this manual also include small screws and bolts.

[0028] figure 1 It is a longitudinal cross-sectional view of a multi-cylinder rotary compressor C according to an embodiment of the present invention. In the figure, 1 is a cylindrical airtight container, and a motor 2 as an electric element is housed on the upper side of the inside, and a compression element 3 driven and rotated by the motor 2 is housed on the lower side. The airtight container 1 is composed of a cylindrical casing portion 1A having an upper end opening and an end cap portion 1B that closes the upper end opening of the casing portion 1A. After the electric motor 2 and the compression element 3 are housed in the housing portion 1A, the end cap portion 1B is covered on the housing portion 1A, and they are sealed by high-frequency welding or the like. The bottom portion in ...

Abstract

The invention provides a multi-cylinder rotary compressor capable of improving compression efficiency, mechanical efficiency and reliability. The bearing (15) is fixed on the inner wall of the airtight container (1), and the cylinders (9, 10) are fixed on the bearing (15), forming a gap (G) between each air cylinder (9, 10) and the inner wall of the airtight container (1). ), the rotary compression element (3) has a blade (24) in contact with the roller (13) in the cylinder, a mounting hole (19) pierced on the cylinder, inserted into the cylinder from the mounting hole and the blade (24) The spring (21) abutted against the roller (13) is provided with a fall-off preventing mechanism on the cylinder (9) to prevent the spring (21) from falling off. Therefore, the internal volume of the airtight container (1) has a surplus, which improves reliability, and the multi-cylinder rotary compression element (3) is miniaturized, thereby improving compression efficiency and mechanical efficiency.

Description

[0001] The application for the present invention is a divisional application of the invention application with the application number of 00119939.0, the filing date of July 3, 2000, and the invention title of "multi-cylinder rotary compressor". Technical field [0002] The present invention relates to, for example, a multi-cylinder rotary compressor equipped with a plurality of cylinders installed in an air conditioner or a refrigerator. Background technique [0003] In the conventional multi-cylinder rotary compressor, an electric element and a rotary compression element are housed in a closed container. The rotary compression element is composed of a middle partition plate, and the first and second sides respectively provided on both sides of the middle partition plate. The cylinder, a rotating shaft having an eccentric portion with a rotation angle shifted by 180 degrees and connected to the electric element, a roller that is respectively fitted with the eccentric portion of th...
