Title: Ink supply device
Inventor: ODA HAJIME
IPC: B41J2/175
Filed: 1981-12-04
Abstract: PURPOSE:To shut off variation in the ink pressure during acceleration and deceleration of the head scanning from its transmission to the head by providing a fluid control valve that has a movable element in a chamber with two openings. CONSTITUTION:In a chamber 3 that has two openings a sphere-shaped movable element with a diameter larger than the openings and smaller than the inner diameter of the control portion of the chamber 3 is installed to form a fluid control valve. This fluid control valve is installed near the head 1 of an ink supply tube 2 that is connected to an ink jet 1. With this arrangement, if, for instance, the head 1 that was moving to the left stops and it is accelerated again to the right, the inertia of the ink in the ink supply tube 2 that was moving to the left gives high pressure change component in the positive direction to a point A, but the movable element 4 moves to the left to close the opening on the left side or in the reversed case, the opening on the right side is closed. Accordingly pressure difference is not transmitted to the head 1.
