ABSTRACT:
The invention relates to a flow regulator in which a diaphragm of elastically deformable material is disposed between a pressure chamber at supply pressure and an end face of a base member having open radially extending grooves. A supply passage extends from the regulator inlet circumferentially around the diaphragm into fluid communication with the grooves and a discharge passage is axially disposed in the base member in fluid communication with the radially inward ends of the grooves. Pressure variations in the supply passage cause the diaphragm to cover varying lengths of the grooves to vary the throttling effects of the grooves. The regulator is adapted for different ranges of flow quantities by providing two or more grooves in the face of the base member and by providing valving apparatus for selectively connecting one or more of the grooves to the supply passage.
