Abstract
A fluid flow regulator (20) comprising: 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).
Claims20
A fluid flow regulator comprising:
- a fluid inlet port and a fluid outlet port;
- at least one open-faced flow control channel defined by a planar bottom and two sidewalls that communicates with the outlet port via a junction and has a cross-section that decreases with distance from the junction;
- an elastic diaphragm;
- a support shelf on which the diaphragm seats;
- wherein to regulate fluid flow, with increasing inlet fluid pressure the diaphragm covers portions of the open face flow control channel that are farther from the junction in a region where the cross-section decreases with distance from the junction.
A fluid flow regulator comprising:
- an inlet cowling comprising an inlet port;
- an outlet cowling joined to the inlet cowling to form an internal volume, the outlet cowling comprising:
- an outlet port in communication with the inlet port;
- and
- at least one open-faced flow control channel formed on the outlet cowling and comprising a bottom and sidewalls, the at least one open-faced flow control channel being in communication with the outlet port via a junction and having a cross-section that decreases with distance from said junction;
- and
- a diaphragm positioned between the inlet and outlet cowlings, the diaphragm contacting a support shelf provided on at least one of the inlet cowling and the outlet cowling.
