Ink feeder for ink jet plotter
专利汇可以提供Ink feeder for ink jet plotter专利检索，专利查询，专利分析的服务。并且PURPOSE:To keep an inner pressure of an accumulator constant even in a non- operative condition, provide a re-printing without having any waiting time when re-use of the accumulator is started and make an image stable by arranging a check valve between a pump and the accumulator. CONSTITUTION:When the screw pump 2 is driven, an inner pressure of the accumulater 16 is increased via check valve 12, and the ink is fed under a pressure to the head after the three-way valve 17 is released. When the three-way valve 17 is closed under a terminated condition, the screw pump 2 is also stopped. Due to this fact, a pressure at the pumping port 4 becomes zero and the pumping pressure is eliminated, but a pressure of the compressed air in the accumulator 16 is restricted by the check valve 12 and the air pressure applied during an operation of the device is kept. Due to this fact, since a pressure of the accumulator is increased in advance even in such a condition as the screw pump 2 is driven and the three-way valve 17 is released so as to perform a reprinting, a normal printing condition may be provided and further a stable printing is performed.，下面是Ink feeder for ink jet plotter专利的具体信息内容。
