In addition, no matter be single cylinder or external air bag, between air cavity and oil pocket, be provided with in the technological scheme of dydraulic shock absorber of floating valve, for example in two technological schemes of Chinese patent " gas-liquid vibration absorber " and " gas-filled type double-piston vibration damper ", they are in the middle of the cylinder barrel at the end is arranged floating valve to be set, but do not instruct people how to be provided with and to be arranged on what position in the specification, do not instruct people how to inflate yet, air-filled pore wherein or the like, be two kinds of technological schemes that are difficult to carry out, although implement reluctantly, its result causes the finished product rate low, working life is short, is difficult to produce in batches.
Summary of the invention
The purpose of this utility model is comprehensively the advantage of existing dydraulic shock absorber, overcomes its shortcoming, a kind of simple in structure, good damping result, long service life is provided and can executes the dydraulic shock absorber that fills high pressure nitrogen to buffer air bag as required.
The utility model comprises cylinder barrel, connecting rod, piston assembly, guider, oil sealing and bottom, in the bottom of bottom, be provided with suspension ring, the bottom in piston assembly is provided with floating valve, floating valve is made of valve body and seal ring, between unsteady valve body and bottom, is provided with spring.
The utility model can be provided with air-filled pore on described bottom, between described supported spring and bottom, the spirit envelope is set, and realizes aerification function.
The utility model can be sealed up at described spirit, and Steel Support is set, and the purpose that Steel Support is set is to improve the function of use of spirit envelope, prevents the condition of high voltage sealing gland distortion of going to the bottom, and guarantees lock gas effect.
The utility model can be provided with through hole on described Steel Support, through hole can be one or more, and the purpose that through hole is set is to improve the combination force of sealing with spirit, improves product percent of pass, and this through hole is as containing the notes attachment hole.
The utility model can be sealed up at described spirit, and the lock compression ring is set, to improve lock gas effect.
The utility model, the purpose that spring is set is: the first, the location of implementing floating valve makes the air cavity volume reach designing requirement; The second, help resetting of floating valve, strengthen effectiveness in vibration suppression; The 3rd, cooperate the spirit envelope, implement inflation.
