Abstract
The utility model discloses a kind of control valve of automobile air conditioner compressor, comprise valve body, on valve body, have exhaust cavity passage, air aspiration cavity passage and balance chamber passage, valve inner is provided with valve rod, valve stem tip is provided with valve ball, valve rod lower end is provided with cone valve and vacuum corrugated pipe, and cone valve is arranged between valve rod and vacuum corrugated pipe.The control valve control valve of automobile air conditioner compressor of the present utility model utilizes vacuum corrugated pipe to experience the variation of pressure of inspiration(Pi), by valve rod, realize the regulation to ball valve and cone valve, change the pressure of balance case, finally make the tilt angle of balance and drive plate change, piston stroke, changes compressor output discharge capacity; Whole control valve is simple in structure, and the work of compressor is stable.
Description
Technical field
The utility model relates to a kind of automobile air conditioner compressor.
Background technique
Automobile air conditioner compressor is divided into fixed displacement compressor and variable compressor, and variable compressor air-conditioning has following advantage: the stability that has 1. kept temperature; 2. the stability that has kept vaporizer low pressure, and vaporizer can frosting; 3. improved the working life of compressor; 4. reduced power consumpiton.General variable compressor is according to the needed pressurized gas scale of construction, and gas temperature, changes compressor inner carrier stroke to change compression ratio, to change its discharge capacity by pressure regulator valve.But existing pressure regulator valve structure is comparatively complicated, compressor operating less stable.
Model utility content
The purpose of this utility model is to provide a kind of control valve of automobile air conditioner compressor simple in structure, makes air condition compressor stable.
The technical solution of the utility model is as follows:
A kind of control valve of automobile air conditioner compressor, comprise valve body, on valve body, have exhaust cavity passage, air aspiration cavity passage and balance chamber passage, valve inner is provided with valve rod, valve stem tip is provided with valve ball, valve rod lower end is provided with cone valve and vacuum corrugated pipe, and cone valve is arranged between valve rod and vacuum corrugated pipe.
On described valve body, be provided with seal ring.
The control valve control valve of automobile air conditioner compressor of the present utility model utilizes vacuum corrugated pipe to experience the variation of pressure of inspiration(Pi), by valve rod, realize the regulation to ball valve and cone valve, change the pressure of balance case, finally make the tilt angle of balance and drive plate change, piston stroke, changes compressor output discharge capacity; Whole control valve is simple in structure, and the work of compressor is stable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of control valve of automobile air conditioner compressor, comprise valve body 10, on valve body 10, have exhaust cavity passage 1, air aspiration cavity passage 6 and balance chamber passage 4,5, valve body 10 inside are provided with valve rod 9, valve rod 9 tops are provided with valve ball 2, and valve rod 9 lower ends are provided with cone valve 8 and vacuum corrugated pipe 7, and cone valve 8 is arranged between valve rod 9 and vacuum corrugated pipe 7.On valve body 10, be provided with seal ring 3.
When engine speed reduces (speed of a motor vehicle reduction) or cooling load increase, by vaporizer vapor pressure out, raise, vacuum corrugated pipe is compressed, when pressure is greater than certain value, ball valve is closed high-pressure channel, and at this moment balance case and low-pressure cavity communicate, and balance room pressure diminishes.The reaction force acting on during piston compression on piston promotes driver plate and balance inclination several angle, and this has just increased piston stroke, has also just increased the discharge capacity of compressor, and refrigerating capacity increases.When engine speed raises (speed of a motor vehicle increase) or when cooling load reduces, the pressure decreased of air aspiration cavity, bellows expansion, ball valve is opened high-pressure channel, and high pressure steam enters balance case balance case pressure to be increased, the active force that acts on the piston back side has increased, balance is back moved, and inclination angle reduces, and piston stroke reduces, air displacement reduces, and power consumption reduces.Like this, control valve regulates air displacement automatically according to the size of cooling load, the scope regulating is 10%～100%, changed traditional compressor by the regulative mode of magnetic clutch clutch and the labyrinth of existing pressure regulator valve, realize system stable and continuous and moved, avoided the impact to motor.
Claims (2)
1. the control valve of an automobile air conditioner compressor, it is characterized in that, comprise valve body (10), on valve body (10), have exhaust cavity passage (1), air aspiration cavity passage (6) and balance chamber passage (4,5), valve body (10) inside is provided with valve rod (9), valve rod (9) top is provided with valve ball (2), valve rod (9) lower end is provided with cone valve (8) and vacuum corrugated pipe (7), and cone valve (8) is arranged between valve rod (9) and vacuum corrugated pipe (7).
2. the control valve of a kind of automobile air conditioner compressor according to claim 1, is characterized in that, is provided with seal ring (3) on described valve body (10).
