DAMPER DEVICE, LIQUID SUPPLY SYSTEM INCLUDING THE SAME, AND INKJET RECORDING DEVICE

摘要

A damper device includes a hollow case main body provided with an opening, a pressure sensitive film attached to the case main body so as to cover the opening, demarcates a liquid storage chamber together with the case main body, and is flexibly deformable internally toward, or externally away from, the liquid storage chamber, an inlet that is in the case main body, is in communication with the liquid storage chamber, and allows the liquid to flow into the liquid storage chamber, an injection outlet that is in the case main body, is in communication with the liquid storage chamber, and allows the liquid to flow out toward the liquid injector, an elastic member coupled with the pressure sensitive film to flexibly deform the pressure sensitive film externally away from the liquid storage chamber, and a pressure receiving plate that is located between the pressure sensitive film and the elastic member and includes a discontinuously joined portion that is discontinuously joined with the pressure sensitive film.

主权项

1. A liquid supply system, comprising:
a liquid supply that supplies a liquid; a liquid injector that injects the liquid; a liquid supply path that communicates the liquid supply and the liquid injector to each other; a damper located on the liquid supply path to supply the liquid to the liquid injector; and a liquid circulation path including an end in communication with the liquid supply path and another end in communication with the damper device; wherein the damper includes:
a liquid storage chamber;an inlet that is in communication with the liquid storage chamber, and allows the liquid to flow into the liquid storage chamber;an outlet that is in communication with the liquid storage chamber, and allows the liquid to flow out of the liquid storage chamber; anda circulation outlet through which the liquid flows out to the liquid circulation path; whereina lower end of the circulation outlet is located at a height lower than an end of the inlet.
