Appeal No. 2004-0111
Application No. 09/930,098
19. In an ink pen adapted for use in an off-axis printer
having a remote ink supply, where the ink pen includes a local ink
supply and a print head adapted to selectively print using ink
from the local ink supply, an improvement comprising:
a valve that selectively supplies the local ink supply with
ink from the remote ink supply;
wherein said valve includes a fluid inlet adapted to receive
ink from the remote ink supply, a fluid chamber having a valve
seat and a valve head, and a fluid outlet adapted to feed ink into
the local ink supply from the fluid chamber;
wherein said fluid chamber is bounded by a compliant
diaphragm, said valve being prefabricated to receive an electric
relay in a manner such that selective actuation of the relay
displaces the compliant diaphragm, said compliant diaphragm
coupled to one of the valve seat and the valve head to perform one
of selective opening and selective closing of the valve in
response to actuation of the relay.
26. An ink pen adapted for use in an off-axis printer having
a remote ink supply, said ink pen comprising:
a local link supply;
a print head adapted to selectively print using ink from the
local ink supply;
a valve opened to selectively supply the local ink supply
with ink from the remote ink supply, said valve including a fluid
inlet adapted to receive ink from the remote ink supply, a fluid
chamber having a valve seat and a valve head, and a fluid outlet
adapted to feed ink into the local ink supply from the fluid
chamber; and
means for maintaining substantially constant volume in the
fluid chamber notwithstanding opening and closing of the valve.
