Abstract
The utility model discloses a vane formula compressor steady voltage ball spring valve, including cylinder body (4) and oil separator (1) of setting on cylinder body (4), cylinder body (3) both sides are equipped with fore bearing (3) and rear bearing (5), are connected with rotor shaft (2) on fore bearing (3), install the ball spring valve that play steady voltage effect between exhaust chamber (8) and back pressure chamber (9) that are linked together on rear bearing (5), and ball spring valve includes one steel ball (6) and one end fixed connection spring (7) on steel ball (6). The beneficial effect of the utility model: ball spring valve makes the friction between blade and the cylinder body reduce, has improved compressor life, the noise reduction.
Description
Technical field
The utility model relates to a kind of stable-pressure device in Compressor Technology field, particularly a kind of rotary blade type compressor voltage stabilizing ball spring valve.
Background technique
Rotary blade type compressor is a kind of novel rotary type compressor that a kind of efficiency is high, volume is little, be widely used in automobile air conditioner system, critical piece comprises cylinder, rotor, blade and antero posterior axis bearing, by the rotation of rotor, each element volume in cylinder is made to complete air-breathing, compression and exhaust process.But because rotary blade type compressor Leaf back-pressure and exhaust pressure constantly change in the course of the work, and stable-pressure device is not set in existing rotary blade type compressor, blade backpressure pressure can be caused excessive and make the working life of compressor not long, being attended by larger noise simultaneously.
Model utility content
For the defect that existing rotary blade type compressor design aspect exists, the utility model provides a kind of rotary blade type compressor voltage stabilizing ball spring valve.
To achieve these goals, the measure that the utility model is taked is:
A kind of rotary blade type compressor voltage stabilizing ball spring valve, comprise cylinder body and be arranged on the oil separator on cylinder body, cylinder body both sides are provided with fore bearing and rear bearing, fore bearing is connected with rotor shaft, be provided with one between the exhaust cavity that rear bearing is connected and back pressure cavity and play the ball spring valve of pressure stabilization function, ball spring valve comprises a steel ball and one end and is fixedly connected on spring on steel ball;
One end of described spring is fixed on bore and is less than in the back pressure cavity of exhaust cavity bore, the steel ball being fixed on the spring the other end to be arranged in exhaust cavity and with the outlet end close contact of back pressure cavity;
The outlet end of described back pressure cavity is the arcuate structure that radian mates with the surperficial radian of steel ball.
The beneficial effects of the utility model: when blade backpressure overpressure, back pressure oil is discharged to exhaust end from ball spring valve, when exhaust pressure is higher than back-pressure, ball spring valve cuts out, and reduces blade backpressure pressure, the frictional force between blade and cylinder body is reduced, improve compressor working life, reduce noise.
Accompanying drawing explanation
Fig. 1, structural representation of the present utility model;
Fig. 2, structure schematic diagram of the present utility model.
Embodiment
For improving the defect that existing rotary blade type compressor exists at design aspect, design a kind of rotary blade type compressor voltage stabilizing ball spring valve (as Fig. 1 ~ Fig. 2), the oil separator 1 comprising cylinder body 4 and be arranged on cylinder body 4, cylinder body 3 both sides are provided with fore bearing 3 and rear bearing 5, fore bearing 3 is connected with rotor shaft 2, be provided with one between the exhaust cavity 8 that rear bearing 5 is connected and back pressure cavity 9 and play the ball spring valve of pressure stabilization function, ball spring valve comprises a steel ball 6 and one end and is fixedly connected on spring 7 on steel ball 6; One end of described spring 7 is fixed on bore and is less than in the back pressure cavity 9 of exhaust cavity 8 bore, the steel ball 6 being fixed on spring 7 the other end to be arranged in exhaust cavity 8 and with the outlet end close contact of back pressure cavity 9; The outlet end of described back pressure cavity 9 is the arcuate structure that radian mates with the surperficial radian of steel ball 6.
Working principle of the present utility model: the ball spring valve be arranged on rear bearing 5 is made up of steel ball 6 and spring 7, and one end communicates with compressor back pressure cavity 9, and the other end communicates with exhaust cavity 8.When back-pressure is higher than exhaust pressure, ball spring valve is opened, and back pressure oil enters exhaust cavity 8 by ball spring valve, reduces back-pressure; When exhaust pressure is higher than back-pressure, ball spring valve cuts out, and makes back-pressure be in pressure constant state all the time.
The beneficial effects of the utility model: when blade backpressure overpressure, back pressure oil is discharged to exhaust end from ball spring valve, when exhaust pressure is higher than back-pressure, ball spring valve cuts out, and reduces blade backpressure pressure, the frictional force between blade and cylinder body is reduced, improve compressor working life, reduce noise.
Simple change and the replacement of those ordinary skill in the art are all within protection domain of the present utility model.
