ABSTRACT:
A method and apparatus for high speed fluid dispensing suitable for ink jet printing comprising the dampening of supply pressure fluctuations during and following operation of the control valve by the incorporation of a resiliently compressible element within the system on the supply side of the valve seat, the element formed of a rubber air bladder placed within the valve chamber, the bladder configured to contract at pressures above the nominal supply pressure and to readily re-expand at pressures below the nominal supply pressure.
