ABSTRACT:
A flow regulator comprises a housing having a passageway for a fluid flowing therethrough from its inlet to its outlet; a resilient sealing member circumscribing the inlet to the passageway; and a flow regulator member overlying the passageway inlet and spaced therefrom by a plurality of axially-extending teeth carried by the flow regulator member. The teeth are spaced circumferentially around the passageway inlet and are engageable at their outer edges with the resilient sealing member such as to define flow paths in the spaces between the teeth. The flow regulator member is movable axially of the passageway in response to the difference in pressure on its opposite faces to press the teeth to different depths into the resilient sealing member and thereby to regulate the flow through the flow paths by varying the dimensions of the spaces between the teeth.
