Embodiment
As shown in Figure 1; The preferred embodiment of the external electric brake control valve of the utility model car air conditioner compressor with variable displacement; It is made up of coil base 1, retaining ring 3, guide sleeve 12, electromagnetic drive mechanism 4, upper valve body 8, following valve body 7, electromagnetic coil assembly 5 and case 16; Said magnetic valve driving mechanism 4 is arranged in the upper valve body 8; Be provided with first spring 11 between moving iron core 10 and the static iron core 13, be provided with the bellows 9 and second spring 14 in the said following valve body 7, be provided with the exhaust cavity passage 17 that connects exhaust cavity Pd between the groove 20 of said valve body 7 down.Valve rod 6 right-hand members are provided with another crankshaft cavity passage 19 of crankshaft cavity Pc, and the pressure of air aspiration cavity Ps is experienced through described bellows 9.
Said second spring 14 is with the said left and right sides end face of valve body 7 down and removably connects, and said valve body 7 down adopts interference fit with said case 16.Said moving iron core 10 upper ends have an air vent 15.Said moving iron core 10 is fixedly connected through said first spring 11 with said static iron core 13.Said upper valve body 8 is equipped with " O " RunddichtringO 2 with said valve body 7 down in groove 20.Said case 16 is provided with air-breathing aperture 18.
Shown in Fig. 2 and 3, the upper end of moving iron core 10 has an air vent 15 in the electromagnetic drive mechanism 4, and moving iron core 10 can be discharged the gas in the enclosed cavity when motion, play lubrication simultaneously, and the valve motion is accelerated.
The working principle of the external electric brake control valve of the car air conditioner compressor with variable displacement of the utility model:
The opening and closing of control valve (being the displacement of said valve rod 6 and said spool 21) mainly promote (said valve rod 6 receives the influence of gas pressure, spring force and frictional force etc. of miscellaneous part less, ignores) by the gas pressure of the electromagnetic force of said electromagnetic coil assembly 5 and said bellows 9 jointly.When pressure of inspiration(Pi) increased, said bellows 9 was compressed, and valve opening turns down; The said valve rod 6 of control valve is consolidated with said static iron core 13 with the said moving iron core 10 of said electromagnetic drive mechanism 4; Independently be equipped with said first spring 11 between said moving iron core 10 and the said static iron core 13; When operating current increases; Said moving iron core 10 promotes said first spring 11 under the electromagnetic force effect, and said first spring 11 promotes said static iron core 13, and said then static iron core 13 drives said valve rod 6 and moves to the direction that valve opening turns down with said spool 21.Be that pressure of inspiration(Pi) and operating current increase, valve opening turns down; Otherwise pressure of inspiration(Pi) and operating current reduce, and valve opening is opened greatly.
When valve opening was opened, said swash plate case was communicated with said exhaust cavity, and refrigerant vapor gets into said swash plate case by said exhaust cavity, and said swash plate case pressure raises.According to compressor variable principle, said swash plate case pressure increases, and swashplate angle reduces, and compressor displacement reduces.When valve opening was closed, said swash plate case pressure reduced, and said swashplate angle increases, and compressor displacement raises.So the operating current through control coil is regulated compressor, realize regulating automatically the function of its displacement size according to the car air conditioner load.
Obviously, the foregoing description only be for explanation clearly done for example, and be not qualification to mode of execution.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all mode of executions.And conspicuous variation of being extended out thus or change still are among the protection domain of the utility model creation.
