Abstract
A system for controlling the flow of pressurized liquid to a head, for example the print-head of an ink jet printing system, through an elastic conduit and including an outer conduit to form a pressurizable jacket surrounding the inner conduit extending between the head and a remotely located liquid flow control valve, the jacket being depressurized by operation of a valve utilizing a controller simultaneously with closure or shut-off of the liquid flow control valve to prevent dribbling or drooling of liquid at the head immediately following shut-off.
