ABSTRACT:
An air piloted hydraulic valve positioned between a source of ink jet fluid and a reservoir containing a plurality of orifices through which streams of continuously flowing droplets are emitted for printing, the valve includes an ink chamber into which the source opens, an outlet opening which permits the ink to flow to the reservoir to form the ink jets, and a bypass opening which permits the flow of ink to pass from the inlet to a remote location for either reuse or dumping. A pair of valve seats are disposed on opposite sides of the ink chamber and a pair of valve sealing members are mounted to a valve stem which extends through the ink chamber and the valve seats so that the sealing members are separately engageable with their respective valve seats as the stem is moved back and forth. A spring urges the valve stem in a direction that causes one of the sealing members to seat on its valve seat to prevent flow of ink from the inlet to the outlet opening and thus permits the flow of ink from the inlet to the bypass opening. An air chamber and movable diaphragm are disposed at the opposite end of the stem and upon introduction of air to the chamber causes the stem to move against the spring and forces the other sealing member to seat against its valve seat and thus closes off the bypass opening and permits ink to pass from the inlet to the outlet opening for supplying ink to the ink jet reservoir.
