Abstract:
1. A method of manufacturing a flow selector disk for a fluid pressure regulator, including the steps of: providing a plate having a first face and a second face; forming at least one baseline orifice in the plate including a first diameter portion adjacent the first face and a second diameter portion adjacent the second face, the first and second diameter portions being spaced a distance from each other to form an annular ring therebetween; forming a central flow portion through the at least one baseline orifice that is in fluid communication with both of the first and second diameter portions, the central flow portion having a relatively smaller diameter than either of the first and second diameter portions; and plastically deforming a portion of the annular ring adjacent the central flow portion to thereby reduce the diameter of the central flow portion.
