本考案は、ボトムバルブ部におけるバルブスプ

衝器のボトムバルブ部構造に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure of a bottom valve portion of a shock absorber that can prevent the valve spring in the bottom valve portion from being sucked into the flow path of the check valve seat to prevent narrowing and clogging of the flow path opening of the pressurizing medium.

れている。 Various types of bottom valves are known for shock absorbers, and are appropriately selected and used. As shown in Fig. 1, bottom piece a, valve b, slit valve c, check valve seat d, etc. are sequentially assembled. One known example is the so-called Sachs-type bottom valve, which is comprised of a valve case e that is arranged in an overlapping manner and covers the valve case e, and a valve spring f that is stretched between the valve case e and the check valve seat d.

つた問題があつた。 However, in this type of bottom valve, when the shock absorber is used for a long time and the piston speed is high, the valve spring is sucked into the flow path of the check valve seat according to the oil flow, and sometimes the valve spring is used for pressurization. There has been a problem in that the flow path opening of the flow path for fluids such as oil, air, gas, etc. is constricted and occluded, resulting in inconveniences such as obstruction of valve operation.

目的を達し得ることを認めて本考案をなした。 The inventor of the present invention has repeatedly devised ways to prevent the passage opening of the pressurizing medium from being constricted or blocked due to the suction of the valve spring into the check valve seat as described above. This invention was devised by recognizing that it is possible to achieve the following.

る。 1 is a bottom piece attached to the cylinder of the shock absorber, 2 is a valve stacked on bottom piece 1 in any number of valves, 3 is a slit valve stacked on valve 2, and 4 is a check valve seat. The slit valve 3 has a convex cross section.
It is placed one above the other. 5 is a valve case that covers these, and 6 is a valve spring, which is a corner portion 8 of the protrusion 7 of the check valve seat 4.
and the corner portion 9 of the valve case 5. However, in the check valve seat 4,
Channel 10 for pressurizing medium such as oil, air, gas, etc.
A recess 12 is cut out around the flow path opening 11 of the flow path 10 at a distance h between the surface 13 of the check valve seat 4 and the surface 14 of the recess 12.

ルブ作動も確実に行なわれ維持される。 Since the bottom valve part of the present invention is constructed in this way, the valve spring 6 is sucked into the flow path opening 11 of the check valve seat 4 according to the flow of oil in a region where the piston speed is high, and the valve spring 6 is sucked into the flow path opening 11 of the check valve seat 4. In the event of stenosis and occlusion, a recess 12 is formed around the flow path opening 11 with a distance h between the surface 13 of the check valve seat 4 and the surface 14 of the recess 12.
Valve spring 6
is supported in contact with the surface 13 of the check valve seat 4, and is spaced approximately by a distance h from the flow path opening 11 opening on the surface 14 of the recess 12, so that the flow path opening 11 is supported by the hanging valve spring 6
There is no possibility of stenosis or occlusion. Therefore, valve operation is also reliably performed and maintained.

つた効果が認められる。 In the present invention, a recess is cut around the pressurizing medium flow path opening of the check valve seat, so there is no constriction or blockage caused by the valve spring being sucked into the flow path opening of the check valve seat as the oil flows.
The effects of this method include ensuring that valve operation is performed and maintained.
