Bearing 16 is supported in cylinder body mesopore, main shaft 9 under the driving of engine, drive mounted in thereon drive disk 12 and with driving
The be hinged swash plate 10 of disk 12 rotates simultaneously, and swash plate 10 and main shaft 9 are into an inclination angle.Multiple pistons 13 are attached separately to each cylinder-bore 21
In, a pair of crawler shoes 8 are set between each piston 13 and swash plate 10, and piston 13 is reciprocal in cylinder-bore 21 in the rotation process of swash plate 10
Motion.When piston 13 is towards top movements, refrigerant gas is sucked into cylinder-bore 21 from suction muffler 6, when being moved towards bottom, by refrigerant
Cylinder-bore 21 drains into discharge chamber 7, to complete the compression to gas, is then discharged in air-conditioning refrigeration loop.
Change compressor capacity, so as to reach control air conditioner refrigerating amount the step of approximately as：When in-car actual temperature with
When target temperature differs greatly, sensor sends signal to computer, executive program, changes（Such as increase）Electrically-controlled valve 34
Driving current, valve body stress change, aperture area change（Access portal between discharge chamber 4 and crankshaft cavity 5 is such as set to reduce to most
It is small）, for compression cylinder, the pressure of crankshaft cavity 5 reduces, and increases so as to the angle of inclination of swash plate 10, refrigerating capacity increase.
One rubber washer 14 is enclosed on main shaft 9, can be connected to the rear end of swash plate 10.The rear end of rubber washer 14 is located at main shaft with one
Jump ring 15 on 9 is spacing.Rubber washer 14 is in Ring-cylindrical, and mesopore passes through for main shaft 9, and outside is periphery, and both ends are plane.Rubber
The material of rubber gasket 14 is selected from the one of which of nitrile rubber class.
Because containing acrylonitrile, oil resistivity is its maximum characteristic, and the higher oil resistivity of acrylonitrile content is better.
