  • Induction ink melter
    Patent number: 8888259
    Abstract: A melting device melts solid ink into liquid ink by passing alternating current through an electrical conductor arranged in coils around a housing. The liquid ink passes from a reservoir, through a spool valve arrangement, and into first and second chambers. The spool valve arrangement only allows liquid ink into one chamber at a time. While the first chamber is being filled, pressure is applied to the second chamber. The pressure applied to the second chamber forces the liquid ink in the second chamber through a filter and an outlet. When the first chamber is filled to a predetermined level, pressure is no longer applied to the second chamber and is applied to the first chamber. The pressure applied to the first chamber moves the spool valve arrangement to block the first chamber. While pressure is applied to the first chamber, the second chamber is filled with liquid ink.
