The self-sealing unit includes a pressure chamber on the liquid supply route and a valving element that opens or closes the liquid supply route to supply the liquid. A biasing member biases the valving element to close the liquid supply route. A film is fixed to the body of the self-sealing unit to demarcate the pressure chamber and causes the valving element to open by being displaced toward the pressure chamber side by a negative pressure acting in the pressure chamber. A convex section is positioned between the valving element and a wall surface of the pressure chamber. The distance between the valving element and the wall surface is shorter than that in other areas, away from the valving element and the wall surface such that the convex section supports the film. | 2010-10-07 |
20100253753 | PRINTING DEVICE FLUID RESERVOIR WITH ALIGNMENT FEATURES - Various embodiments of a printing device fluid reservoir with alignment features and various embodiments of a printing device fluid reservoir chassis with alignment features are disclosed. According to some aspects of these embodiments, the alignment features are grouped together near an ultimate connection point between a fluid reservoir and a chassis to increase design freedom on other regions of the fluid reservoir/chassis. Other aspects of these embodiments include specially designed and located alignment features of a fluid reservoir that engage specially designed and located alignment features of a chassis in sequence throughout the process of inserting the fluid reservoir into the chassis in order to facilitate simple and effective engagement. | 2010-10-07 |
