Specific embodiment
Below in conjunction with accompanying drawing the utility model is made concrete further instruction.
As shown in the figure, comprise air reservoir 1, cylinder 2 and screw 3, air reservoir 1 is inserted in the cavity volume of cylinder 2, screw 3 is placed on the air reservoir 1 and is bolted on the air cavity mouth of cylinder 2, the opening of its described air reservoir 1 is bolted with piston 4, be connected with tracheae 5 on the piston 4, tracheae 5 one ends are provided with air throttle 6 and one-way valve 7, place relevant air tube 8 in the tracheae 5.
Described pass air tube 8, air throttle 6 and one-way valve 7 are integrated forming, by extending solar term pipe 602 on the connecting base 601, place relevant air tube 8 in the solar term pipe 602, there is return-air hole 603 to constitute air throttle 6 on the solar term pipe 602, solar term pipe 6 pipe shafts also have air inlet side opening 701, are with gum cover 702 on the air inlet side opening 701 and constitute one-way valve 7.
Described solar term pipe 602 pipe shafts are provided with protuberance 604 in the form of a ring.
Described pass air tube 8 one ends are provided with columned syringe needle 801, close on the air tube 801 and are with seal ring 802, seal close cup 802 1 sides and are close to syringe needle 801 sides.
Described piston 4 is provided with the intracavity inter-connection of through hole 401 and tracheae 5, through hole 401 wherein one section be the inner funnel shape.
The circular surfaces of described air reservoir 1 is provided with groove 101 in the form of a ring, and the interior recess of groove 101 has seal ring 102.
Circular surfaces is provided with groove 402 in the form of a ring on the described piston 4, and recess has seal ring 403 in it, with the seal ring 102 formation application of anti-leakage layers on the air reservoir 1.
Working principle is: when the user promotes cylinder 2, because the piston 4 of air reservoir 1 is when move in cylinder 2 bottoms, automatically produce certain pressure, in very little stroke, close air tube 8 and backed down, air reservoir 1 air pressure flows to cylinder 2 in and compression gas-pressure to form the very fast change of elastic force that superposes of two air pressure big; When the pressure of the gas in the cylinder 2 surpasses air reservoir 1 internal air pressure, gas in the cylinder 2 backflows by one-way valve 7 on the air reservoir 1 in the air reservoir 1, when air reservoir 1 is shifted the end onto, whole gas are pressed in the air reservoir 1 during cylinder 2 bottom surfaces, when just piston 4 was to cylinder 2 bottoms simultaneously, the gas of cylinder 2 was all compressed into air reservoir 1; Air reservoir 1 atmospheric pressure is with reaction thrust, and beginning is given vent to anger in cylinder 2 by throttle valve 6, and air reservoir 1 is returned, owing to the gas pressure that slowly refluxes by throttle valve 6 makes piston 4 be shifted onto former initial position by slack-off speed automatically; Be set at certain-length owing to close air tube 8 length simultaneously, when piston 4 returns to certain-length, pushed to by air pressure on the through hole 401 of piston 4 because close air tube, it closes seal ring 802 its through holes 401 of sealing on the air tube 8, be in this moment closes gaseity, has formed the use that goes round and begins again; The effect of closing air tube 8 is that control cylinder 2 internal air pressures and air reservoir 1 air pressure have automatic saturated phenomenon; Owing to be the gentle pressure ratio same principle of carrying capacity size, so close air tube 8 control atmospheric pressures and be the reasonable proportioning mutually of carrying capacity, throttle valve 6 is that the control back-flow velocity reaches the deceleration purpose again, and one-way valve 7 is used for to air reservoir 1 air inlet.
Because control cylinder 2 internal air pressures and air reservoir 1 air pressure meeting middle pressure when load capacity is maximum, pulling force adds downward maximum load power when the user pulls down (thrust), and pulling force will be very little; When be carrying capacity when very little because the required very small piston of air pressure is shifted the position very soon onto is closed an air tube 8 and close, so that cylinder 2 atmospheric pressures are deposited is very little, can diminish so pull down also; This air pressure telescopic link also can be applied to train, steamer, lathe and motorcycle or the like.
