Brief description of the drawings
Fig. 1 the structural representation of present invention.
Embodiment
Shown in Fig. 1, be related to one kind can bidirectional modulation formula buffer, including cylinder body 1 is provided with to shake in the cylinder body 1 and swashs pipe
2, the left end for shaking sharp pipe 2 is provided with the sharp ttom of pipe seat 3 that shakes, and sharp 3 outer ends of ttom of pipe seat that shake are provided with for adjusting described shake
Swash the base gland 4 of the left end relative position of pipe 2；The right-hand member for shaking sharp pipe 2 is disposed with bearing 5 and the sheath 6 that is covered with dust；It is described
Shake and be provided with piston head 10 and piston 11 in sharp pipe 2, the piston head 10 and piston 11 pass through axostylus axostyle 19 and the one end of piston rod 18
Connect, the other end of piston rod 18 runs through the bearing 5 and the sheath 6 that is covered with dust, and extend to the cylinder body 1 and connect outside with cylinder cap 8
Connect；The sharp pipe 2 that shakes is provided with multiple throttle orifices 15 on the side wall positioned at the piston 11, it is described shake sharp pipe 2 positioned at
A spill port 17 is provided with the opposite side wall of the piston 11；On inboard wall of cylinder block between the throttle orifice 15 and spill port 17
It is formed with oil-recovery tank；Sponge 12 is provided between the bearing 5 and cylinder body 1；The bearing 5 is positioned at the sheath 6 that is covered with dust
Side has been embedded in oil sealing 13, and the sheath 6 that is covered with dust is covered with dust 14 being embedded in positioned at the outer end side of cylinder body 1；Wherein, institute
Bearing 5 is stated to be set to be provided with second step knot on first step structure, the cylinder cap in the outer end portion positioned at the cylinder body 1
Structure, spring 25 is provided between the first step structure and the second step structure；In the first step structure also
It is provided with the adjusting set 7 for being used to adjust the sharp right-hand member relative position of pipe 2 of shaking being connected with the cylinder body 1.
In use, external impetus drives piston rod 18 to be moved to the left by cylinder cap 8, piston rod 18 promotes piston 11 to moving to left
Dynamic, spring 25 is compressed, the fry dried food ingredients life extruding of the left end lumen portion of piston 11, and now fluid is offered along on by the sharp pipe 2 that shakes
Throttle orifice 15 enters the gap of shake sharp pipe 2 and the inwall of cylinder body 1, and the right-hand member cavity of piston 11 is then entered by spill port 17
Interior, the oil pressure resistance of fluid gradually increases so that the two ends oil pressure amplitude of variation of piston 11 diminishes, until the both sides cavity of piston 11
Interior oil pressure balance.After external impetus is cancelled, piston 11 moves right in the presence of spring 25, the oil of the left end of piston 11
Chamber increases, and oil pressure reduces, and the fluid of its right-hand member is discharged from spill port 17, and enters the left end of piston 11 by throttle orifice 15, and
Under the elastic force effect of spring 25, piston 11 is promoted to reset.
