ABSTRACT:
In an ink jet recording apparatus having an opening for ejecting ink and a cap for covering the opening, a suction recovery device includes a suction pump. The suction pump includes a cylinder communicating with the inside of the cap, a piston with a rotatable disc, and a partition. The disc rotates so as to move the piston along a longitudinal axis of the cylinder between an initial and an operative position. The partition is mounted in the cylinder and moves with the piston, abutting an end of the cylinder when the piston is in the initial position and abutting the piston after the piston has moved a predetermined distance therefrom toward the operative position. A sealed suction chamber is thus formed ill the cylinder. A negative pressure inside the cap suitable for recovering ink ejection from the opening is selected by selecting a suitable angular displacement of the disc.
