| description | A liquid dispensing device is disclosed in which there is a movable needle valve operable to open and close a valve seat located within the nozzle of the dispensing device. The needle valve is guided by a guide bushing contained within the nozzle bore. A very small radiused semi-spherical end surface on the nozzle has been found to eliminate stringing of viscous liquid materials dispensed from the nozzle, particularly when the end surface is combined with a needle valve which is maintained concentric with the nozzle orifice by the guide bushing contained within the nozzle bore. |
