Problems solved by technology

The method that can change the capacity of the compressor is to control the driving part, that is, to control the number of revolutions of the motor, thereby changing the capacity of the anti-phase method, but the cost of the electrical circuit control device and parts used in this method is relatively high, so Increase the manufacturing cost of the product, increase the unit price of the product, and reduce the competitiveness of the product

Embodiment Construction

[0048] Below, the structure of the present invention will be described in detail in conjunction with the drawings and embodiments.

[0049] Fig. 4a and Fig. 4b show the structure and operating state of the embodiment of the present invention, wherein Fig. 4a is a horizontal cross-sectional view showing the state of inner and outer compression.

[0050] As shown in the figure, in the present invention, the linear slider 54 provided with the circular vane 51 is provided with the linear slider 54 of the circular vane 51 on the sliding guide surface 54b of the cylinder 4 formed in parallel to each other, and is in sliding contact with the outer side of the linear slider 54. A slide valve 120 is provided on the inner side of the facing cylinder 4 .

[0051] As shown in FIG. 5a, the linear slider 54 generally forms a right-angled hexahedron structure. On the sliding contact surface corresponding to the sliding guide surface of the cylinder, a pair of sides symmetrical to each other ...

Abstract

The volume changeable device of a circling vane compressor comprises the compressing section, driving section, round vanes with circling vanes of the compressing section, compressing chamber formed by the ring space and outside of the cylinder interior and the said round vane having a linear slider in straight reciprocating movement along the cylinder's sliding guide face, and a pair of side through channel symmetrically set on both sides of the broken part with whose middle as the center on the sliding contact surface one side of the linear slider. Opposite to the linear slider, inside the said cylinder, a sliding valve is set to move forward, set back, contact or open the broken part driven by the driving part. With circling vanes circling in the cylinder with simple valve operation, it can realize compression model change both in the inside compressing chamber or the outside compressing chamber, and change the volume of the compressor, not only ensuring the using economy of the compressor, but also preventing the abrasion for relevant components and supply waste while turning on or off the compressor.

Description

technical field [0001] The present invention relates to an orbiting vane compressor, and in particular to having two conversion modes that can selectively perform compression in the inner compression chamber of the orbiting vane compressor or perform compression in both the inner and outer compression chambers, thereby enabling A capacity variable device for an orbiting vane compressor that changes the capacity of the compressor. Background technique [0002] Usually, the orbiting vane compressor forms inner and outer compression chambers inside the cylinder through the orbiting motion of the vanes. The compressor in Figure 1 is a low-pressure sealed refrigerant compressor used in refrigerators and air conditioners. moving compressor. [0003] In the low-pressure orbital compressor, the driving part D and the compressing part P are arranged inside a casing 1, and the driving part D and the compressing part P are supported by the main frame 6 and the sub-frame 7 by the upper...
