Outside first end, the cylinder body 1 is built with buffer solution；The piston component includes the sealing ring 4 of piston body 5 and first, the work
An annular groove 5.7 is provided with cock body 5（With reference to Fig. 7）, first sealing ring 4 can be in the annular groove 5.7 along cylinder
Body is moved axially；Wherein, with reference to Fig. 7-10, the first side wall 5.1 of the side of annular groove 5.7 of the piston body 5 was provided with
Oily breach 5.11,5.12 is connected with the annular groove 5.7, and the second sidewall 5.2 of the opposite side of annular groove 5.7 is provided with
Quantified oily passage 5.20；Wherein, it is described to quantify oily passage 5.20 to be set along the axial annular of the piston body, it is described fixed
The entrance 5.21 for measuring oily passage 5.20 is connected with the annular groove 5.7, the outlet 5.22 for quantifying oily passage 5.20
On the perisporium for being arranged on the piston body 5.
In the present embodiment, row buffering is entered to piston body 5 using buffer solution, realized on the simplification of mechanical structure, piston body 5
Annular groove 5.7 is provided with, and was respectively arranged with the second sidewall 5.2 of the first side wall 5.1 oily breach 5.11,5.12 and
Oily passage 5.20 was quantified, when piston rod 3 is moved to outside cylinder body 1（With reference to Fig. 5 and Fig. 6）, can be moved in annular groove 5.7
Sealing ring 4 can the second sidewall 5.2 of closed piston body 5 periphery so that liquid can only pass through from oily passage 5.20 is quantified, by
In quantifying, the oily aperture of passage 5.20 was smaller, and the amount of liquid that the unit interval is flowed through at a particular pressure is restricted, so can rise
To good cushioning effect.When piston rod is moved into cylinder body, sealing ring 4 closes the periphery of the first side wall 5.1 so that liquid
Annular groove 5.7 can be penetrated into by the periphery of second sidewall 5.2 and entered oily breach 5.11,5.12, due to excessively oily breach
5.11st, 5.12 is larger, therefore move will be relatively light for the direction into cylinder body 1 of piston rod 3.In addition, as shown in Figure 10, this practicality
Quantified axial annular of the oily passage 5.20 along piston body in new to set, that is to say, that it is a ring junction to quantify oily passage
