摘要： An inkjet pen is disclosed having an interior chamber containing a pressure regulator. A filter within the interior chamber substantially surrounds the pressure regulator, providing a large filter surface area, and hence a low resistance to ink flow. The filter may be formed of a pleated filter material; the filter material may be retained by a rigid ink passage flange and a filter cap.

摘要： 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.
摘要翻译：本发明涉及一种具有由用于向打印头提供墨水的致动器致动的隔膜泵的类型的墨水供应。隔膜泵包括隔膜和底盘。隔膜具有形成在其中的整体压板部分。底盘和隔膜限定了一个可变的容积室。底盘具有设置在其中的偏置部分，用于接合整体压力板部分以沿远离底盘的方向推压压板。压板迫使隔膜离开底盘，以扩大可变容积室。
