Abstract
A marking fluid valve for a marking fluid delivery system of a media marking device. The marking fluid valve includes a resilient body having first and second opposite ends in fluid communication with one another, with the first end having a pair of opposed lips. The pair of opposed lips define a normally closed slit extending therebetween. Compressing the first end of the resilient body along axes of the lips deforms the resilient body from a closed position, in which the lips are in contact with one another to close the slit and prevent marking fluid from passing through the slit, to an open position, in which the lips are spread at least partially apart from one another to enable marking fluid to pass through the slit.
