6.5.5.3 Nozzle plate
The jet is made up of a precious stone with the actual jet bore. The precious stone is
held in a steel plate in order to enable simple replacement and adjustment of the ink jet.
The diameter of the bore is between 40-70 micrometers depending on the design of the
jet.
An O-ring is secured to the nozzle plate with a clamping plate and two slotted screws to
seal the gutter when the jet is closed. The jet is pressed against the spray body with a
fixing screw. This produces a liquid-tight and yet movable connection (see illustration
spray body with oscillator).
6.5.5.4 Nozzle seal with gutter (Nozzle closure)
The nozzle seal prevents the drying of the ink in the jet, the gutter (catcher pipe) and the
suction pump during operational standstill.
This is achieved with an electrical spindle drive which moves the gutter in the direction of
the jet from the writing position to the jet and in the reverse direction when switching on.
The nozzle seal is a unit which can be completely replaced in case of need.
