Liquid Cartridge
First Claim
1. A liquid cartridge mountable on a liquid droplet ejection device including an ejection head for ejecting liquid droplets and a sub-tank for temporarily storing a liquid to be supplied to the ejection head, the liquid cartridge comprising:
- a liquid chamber configured to store a liquid therein, anda pump unit configured to generate a pressure for the liquid stored in the liquid chamber to be supplied to the sub-tank, the pump unit including;
a cylinder;
a piston mounted in the cylinder slidably in a sliding direction, the cylinder and the piston configured to define a pressure chamber communicating with the liquid chamber;
a force transfer member coupled to the piston and including an engagement portion and a support portion which is positioned opposite the engagement portion, the engagement portion configured to engage a drive member of the liquid droplet ejection device and to receive a drive force from the drive member to displace the piston; and
a support member configured to contact the support portion to support the force transfer member to be movable in the sliding direction.
