Definitions

  • a discharge port of the jet pump 24 is connected to a discharge line 34 through which the compressed air and the liquid sucked in via the drain passages 32 may be discharged. While the air is discharged into the atmosphere, optionally via a filter, the liquid discharged via the discharge line 34 may be collected in a container 36.
  • a helical compression spring 66 is provided between the bushing 60 and the valve body 54 for biasing the valve body and the jet pump 24 downwards in Fig. 2 .
  • the force of the spring 66 is overcome by the pressure of the compressed air acting upon the bottom face of the nozzle 48 and driving the jet pump.
  • the ink chamber 14 communicates with the jet pump 24 and liquid is sucked-in via the drain passages 32.
