FLUID SUPPLY AND LIQUID SPRAYING Russian patent published in 2017 - IPC B41J27/04 

FIELD: machine engineering.

SUBSTANCE: liquid supply device is provided with a liquid containing chamber, a transport tube for sending liquid inside the chamber to the liquid spraying device, first and second elements surrounding the tubular on both sides, and a cam that determines the position of the first element relative to the second element. The tube is equipped with a flexible part, which is elastically deformed and flattened. In the first angular position, the cam disposes the first element so that there is a gap that allows the fluid to flow within the part between the first and second elements. In the second angular position, the cam disposes the first element so that the flexible part is flattened by the first and second elements, and the liquid can not flow inside.

EFFECT: reduces the likelihood of liquid escaping from the liquid spray device when the fluid supply device moves relative to the liquid spray device.
