摘要: A printing apparatus which includes a support for paper and a plurality of printing dies for making impressions on the paper. A reciprocally driven hammer is employed for causing the dies to form the impressions, and the hammer is supported by spring arms which are, in turn, attached to a fixture. This fixture includes an opening freely receiving the hammer whereby the hammer is movable without contact with the fixture. A portion of each spring arm is attached to the hammer at forward and rearward locations, and other portions extend outwardly of the hammer axis whereby the hammer is stabilized at all times. The spring action normally biases the hammer away from the dies, and drive force is imparted in opposition to the spring force as by an electrical coil attached to the hammer and situated within a magnetic field.

摘要: A priming system for ink jet printers includes an ink tank, an ink supply line, an ink bypass line and a valving arrangement which alternately permits either pressurized ink to be supplied to a remote printhead for printing purposes or unpressurized ink to be drawn to the printhead by use of a vacuum source applied to the bypass line.

摘要: A unitary pump, regulator valve/pulsation dampener, and interconnecting passageways is provided. The regulator valve/pulsation dampener includes a flexible member disposed in a chamber arranged between the fluid input and fluid output. The diaphragm flexes as a function of the pressure in the chamber to control the opening and closing of a bypass valve member and, in addition, damps out both high and low frequency pulsations generated in the ink by the pump. When the pressure in the system increases beyond a predetermined limit the valve member is opened to divert some of the fluid flow into a bypass passageway until the pressure falls below the predetermined limit. The pressure limit in the system can be varied by adjusting the external pressure applied to the flexible member using an adjustment screw and compression spring.
