Embodiment Construction
[0038] The structure of the present invention will be described in detail below in conjunction with the drawings and embodiments.
[0039] Fig. 3 is a schematic diagram of an exploded structure of an embodiment of the present invention.
[0040] As shown in the figure, in the present invention, a valve working groove 110 is formed under the cylinder 5 . The valve working groove 110 has the inner and outer suction holes 110a, 110b in the cylinder communicated with the side suction port 51 of the cylinder 5, and the inner and outer discharge ports 53a, 53b communicated with the inner and outer compression chambers of the cylinder 5. A valve rotating plate 120 having a shape corresponding to the valve working groove 110 is rotatably installed on it.
[0041] The valve rotating plate 120 is formed with the inner valve suction port 121, the outer communication suction port 123, the inner communication suction port 126 and the outer valve suction port 129 aligned with the cylinder ...

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 accessory bearing, 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] Fig. 1 is a longitudinal sectional structural diagram of a common rotary rotary vane compressor. [0004] As shown in Fig. 1, 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 vertical ...
