摘要:
A pressure regulator apparatus usable with an aerosol supply device containing a fluid includes an inflatable diaphragm unit including an upper surface member, a lower surface member, and a diaphragm chamber formed between the upper surface member and the lower surface member, an output port member having an output cavity and an output port, at least a portion of the output port member is disposed within and in fluid communication with the diaphragm chamber, a valve actuator including an actuator cavity and one or more actuator openings in fluid communication with the output port, at least a portion of the valve actuator is moveably disposed within the output cavity, an input port member having an input port configured to allow the fluid to enter the actuator cavity, at least a portion of the input port member is disposed proximate to the actuator cavity, and an axial flow path extending between the input port and the output port, and configured to allow the fluid to selectively pass in a substantially axial direction therethrough, wherein the valve actuator moves to close and open the input port based on an inflation status of the inflatable diaphragm unit to regulate a pressure of the fluid to be transported from the inflatable diaphragm unit substantially constant.

A wide-array inkjet printhead assembly includes a carrier and a printhead die. The carrier includes a substrate and an electrical circuit. The substrate has a first side and a second side such that the electrical circuit is disposed on the second side of the substrate. The printhead die is mounted on the first side of the substrate and electrically coupled to the electrical circuit. Thus, electrical connection is established between the first side of the substrate and second side of the substrate.

The present invention relates to an ink supply of the type having a diaphragm pump that is actuated by an actuator for providing ink to a printhead. The diaphragm pump includes a diaphragm and a chassis. The diaphragm has an integral pressure plate portion formed therein. The chassis and the diaphragm define a variable volume chamber. The chassis has a bias portion disposed therein for engaging the integral pressure plate portion to urge the pressure plate in a direction away from the chassis. The pressure plate urges the diaphragm away from the chassis to expand the variable volume chamber.

A fluid ejection cartridge includes a fluid container that has both a fluid inlet and a fluid outlet. The fluid ejection cartridge has one or more fluid ejectors fluidically coupled to the fluid container outlet and a fluid valve fluidically coupled to the fluid container inlet. The fluid ejection cartridge has a filter assembly having a compliant portion with an internal volume fluidically coupled to the fluid container outlet such that the internal volume changes when fluid flows into the fluid container.
