Abstract
A fluid jet print head includes a manifold defining a fluid receiving reservoir and at least one orifice communicating with the reservoir. An inflation means cooperates with the manifold and expands within the reservoir to displace fluid from the reservoir. The inflation means contacts the manifold, thus sealing the orifice and terminating fluid flow through the orifice. In a first embodiment, the inflatable means includes an elastic diaphragm which may be inflated to extend into the reservoir. In a second embodiment, the inflatable means includes an elastic tube, sealed at a first end thereof and extending into the reservoir. When pressurized air is applied to the interior of the tube, the tube expands, filling the reservoir and sealing the orifices.
