Embodiment
Specify the present invention below in conjunction with embodiment.
Embodiment
As Fig. 2 and shown in Figure 4, axial pressure release realizes energy-conservation scroll compressor under a kind of high speed thereby the invention provides, comprise protecgulum 10, bearing and bent axle 4 are installed in protecgulum 10 holes, end face has push pedal 6, flexible body device 7 is installed between push pedal 6 and protecgulum 10 counter sinks, setting-up eccentricity cover 3 on the bent axle 4, the movable orbiting scroll 2 of mounting strap bearing on the eccentric bushing 3, there is anti-rotation mechanism 5 movable orbiting scroll 2 bottoms and contacts with push pedal 6 end faces, the movable orbiting scroll molded lines is meshed with the static vortex disk molded lines and forms the crescent shape cavity volume, and static vortex disk 1 back side is equipped with baffle assembly 9 and forms hyperbaric chamber with bonnet 8.The restriction with anti-rotation mechanism 5 of turning clockwise along with bent axle 4, movable orbiting scroll 2 is done revolution motion around static vortex disk 1 center, the crescent shape cavity volume that makes static vortex disk 1 and movable orbiting scroll 2 form moves from outside to inside and volume constantly diminishes, pressure raises, and enters hyperbaric chamber until pushing dividing plate 9 open from the discharge of static vortex disk 1 bottom outlet.
As shown in Figure 3, flexible body device 7 is movable orbiting scroll 2 and static vortex disk 1 axial contact seal under free situation, and the clearance D 1 between push pedal 6 and protecgulum 10 end faces keeps 0.01～0.05mm.As shown in Figure 5, when Compressor Discharge Pressure reaches setting value F (F value size is tried to achieve by the required refrigerating capacity of joining vehicle), flexible body device 7 is subjected to force compresses, makes push pedal 6 and movable orbiting scroll 2 movement therewith, and movable orbiting scroll 2 forms 0.01～0.05mm axial clearance D2 pressure release with static vortex disk 1.When being lower than setting value F, flexible body device 7 restores and makes movable orbiting scroll 2 axially contact the assurance refrigerating capacity with static vortex disk 1.Refrigerating capacity, exhaust pressure, power consumption will remain on an equilibrium value after compressor surpasses certain rotating speed.
