Abstract
An ink manifold defining multiple fluid flow paths has openings arranged for detachable connection with conduits in an interface. Shut off valves at each of the openings respectively, are biased open. An actuator biased to a closed position by a resilient element, where it holds all the shut off valves closed. The actuator engages the interface such that moving the interface into connection with the openings simultaneously moves the actuator to an open position where the shut off valves are able to open. The resilient element generates a bias greater than a combined bias exerted by the shut off valves on the actuator.
Claims10
An ink manifold defining multiple fluid flow paths, the ink manifold comprising:
- a plurality of openings arranged for detachable connection with conduits in an interface;
- a plurality of shut off valves at each of the openings respectively;
- an actuator biased to a closed position by a resilient element, such that the actuator holds all the shut off valves closed when in the closed position, the actuator being configured for engagement with the interface such that moving the interface into connection with the openings simultaneously moves the actuator to an open position where the shut off valves are able to open;
- wherein,
- the resilient element generates a bias greater than a combined bias exerted by the shut off valves on the actuator,
- wherein each shut off valve comprises a biasing member configured for biasing each shut off valve into an open position.
