Abstract
A pressure regulating valve for an inkjet printhead. The valve includes: a fluid flow path defined between a valve inlet and a valve outlet; an orifice positioned in the flow path; a movable valve member configured for regulating a fluid flow rate through the orifice; a regulator chamber having the valve outlet and including a diaphragm operatively connected to the valve member, such that movement of the diaphragm moves the valve member relative to the orifice; and a biasing mechanism for resiliently biasing the diaphragm away from the orifice. An outer surface of the valve member is non-linearly flared away from the diaphragm.
