流体流量控制调节器
摘要：
一种流体流量调节器(20)，其包括：流体入口孔(34)和流体出口孔(54)；至少一个露面流量控制槽(60)，其由平面底部(62)和两个侧壁(64)界定，所述露面流量控制槽(60)在交叉口(66)处与出口孔(54)相通，且具有随着远离交叉口而减小的截面；弹性膜片(40)；支撑架(58)，膜片(40)安置于支撑架(58)上，且支撑架(58)沿平行于至少一个槽(60)中的每一个的底部的平面轮廓支撑膜片(40)；其中，为了调节流体流量，随入口流体压强的增加，膜片(40)在截面随着远离交叉口(66)而减小的区域覆盖距交叉口(66)较远的露面部分。
摘要（英）：

A fluid flow regulator (20) comprises: a fluid inlet port (34) and a fluid outlet port (54); at least one open-faced flow control channel (60) defined by a planar bottom (62) and two sidewalls (64) that communicates with the outlet port (54) at a junction (66) and has a cross-section that decreases with distance from the junction; an elastic diaphragm (40); a support shelf (58) on which the diaphragm (40) seats and which supports the diaphragm (40) along a planar contour parallel to the bottom of each of the at least one channel (60); wherein to regulate fluid flow, with increasing inlet fluid pressure the diaphragm (40) covers portions of the open face that are farther from the junction (66) in a region where the cross-section decreases with distance from the junction (66).
