Embodiment

Be described in more detail below in conjunction with the technological scheme of embodiment to this patent.

Refer to Fig. 1, a kind of automobile absorber, comprise oil storage cylinder 1, clutch release slave cylinder 2, piston rod 3, base 4, piston 5, outer shell 7, first one-way valve 9, second one-way valve 10, orifice valve 15, netted lid 18 and elastomer 19, described clutch release slave cylinder 2 is arranged in oil storage cylinder 1, oil storage cylinder 1 is arranged in outer shell 7, outer shell 7 is also the shell of this vibration damper, base 4 is fixed on the bottom of clutch release slave cylinder 2 and oil storage cylinder 1, base 4 pairs of clutch release slave cylinders 2, oil storage cylinder 1 plays the effect of location, gap between the madial wall of outer shell 7 and the outer side wall of oil storage cylinder 1 forms external passage 11, oil storage chamber 12 is formed between the madial wall of oil storage cylinder 1 and the outer side wall of clutch release slave cylinder 2, be active chamber 6 in clutch release slave cylinder 2, the inner of piston rod 3 is provided with piston 5 and is positioned at active chamber 6, outer end is stretched out outside active chamber 6 and is connected with outside load-bearing material, piston 5 is provided with some discharge orifices 17, discharge orifice 17 is provided with the first one-way valve 9, flexible body 19 and netted lid 18 is provided with from bottom to top bottom active chamber 6, some pod apertures 20 and pore 21 is provided with in elastomer 19, orifice valve 15 is fixed with between clutch release slave cylinder 2 bottom and base 4, orifice valve 15 is communicated with the second one-way valve 10, first one-way valve 9, the direction of the second one-way valve 10 one-way conduction is identical, and pressure oil can only be made to flow from cavity of resorption toward epicoele, chamber, the end 16 is formed between orifice valve 15 and base 4, chamber, the end 16 is communicated with oil storage chamber 12, chamber, the end 16 is communicated with by oil guiding hole 14 with external passage 11, one end of described opening 8 is connected with the top of active chamber 6, the other end is connected with the top of external passage 11, needle-like outlet valve 21 is communicated with active chamber 6, valve type oil hole 23 is communicated with oil storage chamber 12, the bottom of outer shell 7 is fixed with bottom 13 by welding.

Working principle of the present invention is: when the present invention works, when piston rod moves up, first closed check valve, second one-way valve is opened, the pressure oil being positioned at epicoele enters into external passage by opening, entered in chamber, the end by oil guiding hole again, then enter into cavity of resorption by orifice valve, the second one-way valve, pod apertures, when piston rod moves down, first one-way valve is opened, second closed check valve, pressure oil in cavity of resorption passes through discharge orifice, first one-way valve enters into epicoele, elastomer compresses, reduce vibrations, epicoele gos deep into due to piston rod, the volume of piston rod in active chamber becomes large, pressure oil in epicoele enters into external passage by opening, enter in chamber, the end by oil guiding hole, in the process of movement on the piston rod, pressure oil, orifice valve, elastomer, discharge orifice, pod apertures etc. produce damping function to the mobile of piston rod, thus realize the object of damping, simultaneously pressure oil is fully carrying out exchange heat by during external passage and outside, reach radiating effect.
