| 摘要 |
The invention is a load sensing reduction valve to reduce parts size drastically and simplify assembly process. The upper rag gear(4) is directly connected to valve operating lever(2) of fluid pressure controlling part(C) attached to frame(A) bracket(B), the lower rag gear(6) fixed to rear axle(E) is symmetrically arrayed to upper rag gear(4), double pinion(8) is interposed between both rag gear(4,6), double pinion(8) is arrayed rotatable around supporting axle(10) which is supported at adequate locations on casing(12), big pinion(8a) and small pinion(8b) are assembled to supporting axle(10) as a live spindle, lower axle rag gear(6) is fixed to rear axle(E) by the lower axle stud(14) and upper rag gear motion is operated through double pinion.
