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 vertical side 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 an electric motor 2 as an electric element is housed in the upper side thereof, and a compression element 3 driven to rotate by the motor 2 is housed in the lower side. The airtight container 1 is composed of two divided parts: a cylindrical case part 1A with an open upper end and an end cap part 1B closing the upper end opening of the case part 1A. After housing the electric motor 2 and the compression element 3 in the casing 1A, the casing 1A is covered with the end cap 1B, and sealed by high-frequency welding or the like. The bottom of the casing portion 1A of the airtight contain...

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 whose application number is 00119939.0, the application date is July 3, 2000, and the invention name is "multi-cylinder rotary compressor". technical field [0002] The present invention relates to a multi-cylinder rotary compressor equipped with a plurality of cylinders, for example, mounted on an air conditioner or a refrigerator. Background technique [0003] In the existing multi-cylinder rotary compressor, the electric element and the rotary compression element are accommodated in the airtight container. An air cylinder, a rotating shaft having an eccentric portion with a rotation angle shifted by 180 degrees and connected to an electric element, rollers that respectively fit into the eccentric portion of the rotating shaft and rotate in the air cylinder, and bearings that close each opening of the air cylinder. [0004] Each cylinder is fixed on the inner wall of t...
