Embodiment 1

[0041] Such as figure 1 As shown, this embodiment provides a variable displacement compressor, including an upper cover assembly 11, a housing assembly 14, and a lower cover assembly 17, the housing assembly 14 is fixed between the upper cover assembly 11 and the lower cover assembly 17 and Form a closed space; also include a rotor assembly 12, a stator assembly 13, which is connected to a power supply to provide driving force; the stator assembly 13 is fixed on the inner peripheral wall of the housing assembly 14; also includes a pump body assembly 15, the pump body The assembly 15 is fixed on the inner peripheral wall of the housing assembly 14 and connected with the rotor assembly 12; the pump body assembly 15 performs periodic compression work under the drive of the rotor assembly 12; it also includes a suction liquid separator 18. The outlet end of the suction liquid distributor 18 is connected to the pump body assembly 15 to provide low-temperature and low-pressure refri...

Embodiment 2

[0054] In the variable displacement compressor of the present invention, when the pump body assembly 15 has two cylinder parts, the variable displacement cylinder part can be an upper cylinder part or a lower cylinder part. Embodiment one is that the lower cylinder part is used as a variable displacement cylinder assembly, such as Figure 10 As shown, the above cylinder parts of embodiment two are used as variable capacity cylinder parts, and the differences with embodiment one are:

[0055] 1. The pin 209 and the spring 210 are installed in the pin hole of the upper cylinder 204 , the upper slide is provided with a slide lock hole 213a, and the pin sealing cover 211 is locked on the upper cylinder 204 .

[0056] 2. The upper flange 203 is provided with a variable volume ventilation hole and a variable volume ventilation channel, which are connected to the tail of the slider.

[0057] 3. The upper partition 205 is provided with a low-pressure vent hole and a low-pressure vent...

Embodiment 3

[0059] The invention is a multi-cylinder variable capacity compressor with three or more cylinder parts. Such as Figure 11 As shown, the differences from Embodiment 1 and Embodiment 2 are:

[0060] 1. The pump body assembly 15 also includes a middle cylinder 111 , a middle partition 112 and a middle sliding piece 113 .

[0061] 2. The variable capacity cylinder can be one or more of multiple cylinders, and the variable capacity compressor has multiple operating modes such as single cylinder, double cylinder, and multiple cylinders.

[0062] 3. At least one or more of the plurality of baffle components is provided with a variable volume vent hole and a variable volume vent channel, which communicate with the tail of the slider.

[0063] 4. At least one or more of the baffle assembly, upper flange, and lower flange is provided with a low-pressure vent hole and a low-pressure vent channel, which communicate with the tail of the pin.

[0064] Compared with prior art, the benef...

Abstract

The present invention relates to the technical field of compressors, in particular to a pump body device and a variable capacity compressor. The pump body assembly is applied to a variable capacity compressor and includes a cylinder part, a slide plate and a pin part. The cylinder part is provided with A plurality of pin holes are opened on the cylinder part, the pin part is arranged in the pin hole and can move along the axis direction of the pin hole, and a slide slot is also opened on the cylinder part, the The sliding vane is set in the sliding vane groove, and the pin hole and the sliding vane groove are connected with each other. This pump body assembly solves the problem of the complex structure of the lower flange of the conventional variable capacity compressor due to the setting of the pin hole. , making the structure and assembly process of the pump body components simpler.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a pump body device and a variable capacity compressor. Background technique [0002] For double-cylinder or multi-cylinder variable capacity compressors, the variable capacity cylinder is generally set as the lower cylinder. The lower end of the lower cylinder has a lower flange, and the pins are placed in the pin holes of the lower flange. However, in the existing variable capacity compressors, the lower cylinder There is a sliding vane in the sliding vane groove, the lower end of the sliding vane is provided with a pin locking groove, the pin is set in the pin hole of the lower flange, and the lower end of the pin is provided with a sealing cover plate. The double-cylinder compressor, because the pin hole is set on the lower flange , and then there are problems of complex structure and high difficulty of assembly process. Contents of the invention [0003] In view of thi...
