Embodiment Construction
[0039] The structure of the present invention will be described in detail below in conjunction with the drawings and embodiments.
[0040] image 3 It is a schematic diagram of an exploded structure of an embodiment of the present invention.
[0041] As shown in the figure, the present invention forms a valve working groove under the cylinder 5 . The valve working groove has in the cylinder, the outside suction hole 110a, 110b that communicates with the side suction inlet 51 of the cylinder 5 and the cylinder, the outside discharge port 53a, 53b that communicates with the inside and outside compression chamber inside the cylinder 5, and in it A valve rotating plate 120 whose shape corresponds to the valve working groove is rotatably installed on it.
[0042] The valve rotating plate 120 is formed with the inside valve suction port 121, the outside communication suction port 123 and the inside communication suction port 126 and the outside valve suction port 129 aligned with ...

The volume changeable device of the rotary vane compressor has an inside and an outside compressing cavity divided by the rotary shaft driven swirl inside the operating cell of the cylinder with suction inlet and inside and outside outlet in the rotary vane compressor. The said rotary shaft is mounted on the accessory bearing with inside and outside outlets. Between the cylinder and the accessorybearing, there exist the suction inlet that conducts or breaks the suction inlet of the cylinder by rotating positively or negatively driven by the driving device, and the valve structure for connecting the flow circuit between the exhausts inside and outside of the cylinder. Through the valve in the inside and outside compressing cavity formed inside the cylinder by rotary vanes with simple operation, it can compress in the inside and outside compressing chamber. Changing the compressor's volume through model variance, it can ensure the economy of the compressor and avoid the wasting of power and related devices and the loss of life of components due to previous starting or shutting off, and therefore improves the quality and reliability of the machine.
Description
technical field [0001] The present invention relates to a rotary vane compressor. In particular, it relates to a capacity variable device of a rotary vane compressor which can compress only in an inner compression chamber or an outer compression chamber by simply operating a valve, and can change the capacity of the compressor according to mode switching. Background technique [0002] Generally, in a rotary vane compressor, a rotary vane rotates inside a cylinder having a suction port to compress refrigerant gas flowing into the cylinder, and there are various types of rotary vane compressors depending on the shape of the vane. [0003] figure 1 It is a vertical section structure diagram of a common rotary rotary vane compressor. [0004] like figure 1 As shown in the rotary vane compressor, the upper side motor part D and the lower side compression part P are enclosed in the casing 1, and the motor part D and the compression part P are connected to each other by a vertic...
