The present invention is further illustrated below in conjunction with working procedure of the present invention.
Behind the car engine start, motor drives clutch pulley 7 by belt and rotates, if air-conditioning switch is not opened, then clutch pulley 7 idle running, not work done, scroll compressor is not worked, if open air-conditioning switch, then clutch energising, clutch pulley 7 and friction plate 8 adhesives that are installed on the bent axle 5 drive friction plate 8 and rotate, and friction plate 8 drives bent axle 5 and rotates, bent axle 5 drives eccentric bushing 6 and rotates, thereby drives vortex moveable disc 3 work.Cooperate the outermost a pair of crescent shape air aspiration cavity 9 that be split into gradually to enlarge by vortex moveable disc 3 and vortex static disc 2 this moment, suck gas, middle a pair of crescent shape intermediate cavity 10 reduces gradually, gas in it is compressed, innermost a pair of crescent shape center cavity 11 associatings also reduce gradually, gas continues to be compressed in it, the exhaust pressure that is higher than the outlet valve 12 that links to each other with crescent shape center cavity 11 up to pressure, outlet valve is opened, pressurized gas are discharged through outlet valve 12 from crescent shape center cavity 11, enter the air-conditioning condenser work done.The moving circle of bent axle 5 revolutions, crescent shape air aspiration cavity 9 closures once, crescent shape intermediate cavity 10 pressurized gass once, 11 exhausts of crescent shape center cavity once, the number of turns of rotating at unit time inside crankshaft 5 is many more, the air displacement in the scroll compressor unit time is just big more.That is to say that the speed of a motor vehicle is high more, the air displacement of scroll compressor is just big more, and refrigeration (heat) ability is just big more, sometimes or even a kind of waste.And scroll compressor of the present invention at first passes through choose reasonable elastomer 19 (spring) when work, and the centrifugal force that produces when utilizing vortex moveable disc 3 rotations overcomes the elastic force of elastomer 19, realizes permanent discharge capacity output.
When the automobile low speed driving, because the effect of elastomer 19 elastic force, make spool 20 block inlet hole 14 (or through hole among the embodiment two 16), crescent shape air aspiration cavity 9 and crescent shape intermediate cavity 10 (or crescent shape center cavity 11) are not communicated with, and scroll compressor is with delivery work.Raising along with car speed, the rotating speed of bent axle 5 also increases, the speed of vortex moveable disc 3 also increases thereupon, spool 20 suffered centrifugal force also increase thereupon, when the elastic force of the suffered centrifugal force of spool 20 greater than the elastomer 19 (spring) that sets, spool 20 outwards moves, at this moment, the inlet hole 14 (or through hole 16) that communicates with crescent shape intermediate cavity 10 (or crescent shape center cavity 11) is opened, the portion gas that was compressed in the crescent shape intermediate cavity 10 (or crescent shape center cavity 11) is by through hole 16, inlet hole 14 enters in the flow control valve 13, passes through dredging flow groove 23 (or pod apertures 24) then from cascading water hole 15, through hole 17 enters in the crescent shape air aspiration cavity 9.So, when galloping, the discharge capacity of scroll compressor revolution is lacked during than low speed, and the rotating speed of bent axle 5 is high more, and the open degree of suction port 14 is big more, and the gas that returns in the crescent shape air aspiration cavity 9 is just many more, and the discharge capacity of revolution is just few more.Thereby no matter can realize that the bent axle 5 of scroll compressor is to run up or during low-speed running the air displacement substantially constant in the unit time.Here need to prove that the rotating speed of the bent axle during flow control valve 13 action (being spool 20 outer moment of moving and making relief opening 14 and dredging flow groove 23 or pod apertures 24 conductings under centrifugal action) is the best rotating speed that freezes during (heat) effect of whole air-conditioning system.
