Abstract
An ink jet printhead includes a mounting frame, an ink supply reservoir secured to the mounting frame and a valve housing secured to the mounting frame, the valve housing including an ink chamber. An ink supply fitting is supported in the mounting frame and includes a bore having a first end communicating with the ink supply reservoir and a second end communicating with the valve housing for feeding ink from the ink supply reservoir to the ink chamber. The fitting includes a valve seat in the bore. A valve member located in the valve housing is mounted for reciprocation in the ink supply fitting bore for selectively sealing against the valve seat in the fitting. A support member supports the valve member so that the valve member can reciprocate in relation to the valve seat to selectively allow a flow of ink into the ink chamber. The valve responds to reduced ink pressure in the ink chamber upon ejection of ink therefrom by a head assembly to open and admit ink into the ink chamber by flow from the reservoir through the fitting.
