Abstract: A flow-controlling unit having a function of limiting the tilting angle of a flow-controlling piece which includes a flow-controlling plate, which is disposed perpendicular to the moving direction of a fluid in a flow channel. The flow-controlling plate includes first fluid through-holes through which the fluid passes and flow-controlling pieces which are provided in a part corresponding to the first fluid through-holes. The flow-controlling pieces are inclined in the direction of the inflow of the fluid and control the degree of opening of the first fluid through-holes by being tilted due to pressure applied from hydraulic pressure of the fluid. A tilting-angle-limiting plate has second fluid through-holes which communicate with the first fluid through-holes, wherein the diameter of the second fluid through-holes is smaller than the diameter of the first fluid through-holes, allowing the flow-controlling pieces to be supported to limit the tilting angle of the flow-controlling pieces.

Abstract: Apparatus and associated methods relate to a solenoid assisted valve including a split collar and a precision sealing valve seat surface with tight dimensional tolerances and substantial performance repeatability. In an illustrative example, the split collar may concentrically mate around a cylindrical bobbin. In some examples, the split collar may include ferromagnetic material alone or in combination with various thermoplastic materials. The placement of the split collar may be adjusted by manufacturing to fine tune placement of a magnetic pole and to customize valve performance, for example. The valve seat may include, for example, an orifice sealed with an elastic stopper. The valve seat may be configured, for example, with specific ratiometric dimensional relationships and flatness specifications. Various solenoid valves may allow manufacturers to tune the location of a solenoid generated magnetic pole, for example, to tailor the valve plunger performance for a wide variety of applications.
