Embodiment 1

[0029] like Figure 1~2 As shown in and 5, the present invention is a variable-displacement air-conditioning compressor, which mainly includes a casing 1, an inclined block 2, a drive shaft 3 and a cylinder group, the drive 3 is fixed on the middle part of the casing 1 through a bearing, and the cylinder group includes four compressors Cylinder, the compressed air cylinder is centered on the axis of the drive shaft 3 and arranged in a circular array. The slant block 2 is cylindrical and includes a drive slope. The drive shaft 3 is fixed at the center of the slant block 2. axis coaxial;

[0030] A groove 4 with a circular profile and a hemispherical cross-section is provided on the slope of the inclined block;

[0031] Compression cylinder comprises cylinder body, piston 6 and piston rod 5, and one end of cylinder body is closed and one end is open, and the closed end 9 of cylinder body is provided with a boss 8 whose diameter is smaller than the inner diameter of cylinder bod...

Embodiment 2

[0036] like Image 6 As shown, a variable-displacement air-conditioning compressor mainly includes an outer frame 2-1, an array of compression cylinders 2-2, and a cam 2-3. The four compression cylinders 2-2 are arranged in an annular array with the rotation axis as the center. , the action direction of the piston rod of the compression cylinder 2-2 is perpendicular to the rotation axis of the drive shaft, and the center of the cam 2-3 is located on the rotation axis of the drive shaft, and the drive ball of the piston rod presses against the outer surface of the cam 2-3 On the contour surface, by turning the cam 2-3, the relative movement of the piston can be made to control the suction-compression-exhaust process of the compression cylinder;

[0037] If you want to increase the temperature inside the car and reduce the cooling capacity, that is, reduce the cooling capacity of the compressor, you can also refer to image 3As shown, close the electromagnetic valve 10 at the i...

Abstract

The invention relates to a variable-displacement air-conditioning compressor, which includes a casing, a cylinder group, a drive block and a drive shaft, and the drive shaft is rotatably fixed on the casing; the cylinder group includes a plurality of compression cylinders, the cylinder includes a cylinder body and a piston, and the cylinder body is closed There are intake valve and exhaust valve at the end, the intake valve and exhaust valve are two one-way valves with opposite conduction directions, the piston is inserted into the cylinder through the open end of the cylinder, and the piston is provided with a piston rod. The end of the piston rod is provided with a hemispherical contact head, and an expansion spring is arranged between the piston and the closed end of the cylinder body. The contact head is pressed against the drive block under the drive of the spring, and the drive block passes through the drive shaft. The rotation of the contact head makes contact with arc surfaces of different heights in the axial direction, and drives the piston to move; the one-way valve on the compression cylinder communicates with the air-conditioning refrigerant circuit through a conduit, and a solenoid valve is also arranged between the one-way valve and the conduit .

Description

technical field [0001] The invention relates to a variable-displacement air-conditioning compressor, which belongs to the field of vehicle-mounted air compressors. Background technique [0002] Vehicle air-conditioning compressors are mainly divided into fixed-displacement compressors and variable-displacement compressors. Variable-displacement compressors can automatically adjust the power output by sensing the set temperature. This variable-displacement compressor is mainly installed inside the compressor. The pressure regulating valve is used to control the output. The energy waste caused by this regulating valve control method is relatively large, and the working state of the compressor itself does not change, and the load brought to the engine is also constant. When the engine load is large At the same time, this type of air-conditioning compressor generally controls the startup and shutdown of the compressor through an electromagnetic clutch. The electromagnetic clutch...
