VALVE AND REGULATOR ARRANGEMENT FOR A PRINTHEAD CARTRIDGE

摘要

Provided is an inlet valve and pressure regulator arrangement for a printhead cartridge. The arrangement includes an inlet body having a skirt engaging portion with a depressible member, and a spacer with a central hub. Also included is a diaphragm with a central opening and a spring positioned by a regulator outlet portion so that said spring biases the central opening of the diaphragm against the central hub. An increase in fluid pressure when the depressible member is operatively depressed overcomes the spring bias to allow fluid to flow from the inlet body to the regulator outlet.
