Claims

[Scope of utility model registration request]

The flow path has an inlet flow path and an outlet flow path which are curved by a partition wall provided inside, and further has an axis arranged at a certain angle with respect to the axis of the inlet flow path. A stop valve type valve body having a hollow chamber located between the passages, provided within the valve body, communicating the inlet passage and the hollow chamber, and having an inner circumferential surface whose diameter decreases from the downstream side to the upstream side. an opening having a shaped shape; a lid attached to the valve body; a spindle supported by the lid and having an axis that coincides with the axis of the opening and capable of moving forward and backward in the axial direction; a cylinder that is integrally provided at a lower end and is movable forward and backward within the hollow chamber so as to communicate with the opening, and whose lower end sealing surface can come into contact with the valve seat of the opening; A valve body that is slidably fitted, has a through hole therein that communicates with the opening, is located on the same axis as the opening, and always forms an orifice between the valve; a spring constant disposed between the valve body and the cylinder such that the valve body is biased away from the opening and the expansion and contraction actions in response to fluid pressure fluctuations are substantially staggered with respect to each other; A constant flow valve comprising a plurality of different springs, and.
