Fluid dispensing apparatus and method of use thereof

Abstract

A dispensing nozzle assembly is provided including a nozzle member provided with one or more dispensing apertures to allow fluid to be dispensed therefrom in use. Closure means are provided on or associated with the nozzle member and movable relative thereto between a closed position, wherein the closure means closes the dispensing apertures and fluid cannot be dispensed from the dispensing apertures, and an open position, wherein the closure means are moved at least partially clear of the dispensing apertures and fluid can be dispensed through the dispensing apertures in use. Switch means are moveable between an “on” position for allowing fluid to flow into the nozzle member for dispensing through the dispensing apertures in use, and an “off” position for preventing fluid flowing into the nozzle member in use. The switch means are arranged such that movement of the closure means relative to the nozzle member moves or actuates the switch means between the on and off positions in use.

         8 . The dispensing nozzle assembly according to  claim 1 , wherein sealing means are provided on or associated with the closure means to seal the dispensing apertures of the nozzle member when in a closed position in use. 
     
     
         9 . The dispensing nozzle assembly according to  claim 1 , wherein fluid conduit means are provided in, on or associated with the nozzle member to allow fluid to flow from a fluid source or actuator assembly to the dispensing apertures of the nozzle member. 
     
     
         10 . The dispensing nozzle assembly according to  claim 1 , wherein the switch means is a magnetic switch or an electromagnetic switch. 
     
     
         11 . The dispensing nozzle assembly according to  claim 10 , wherein the magnetic switch includes magnetic means or a magnetic member on or associated with one of the closure means or a housing portion of the assembly, and a magnetic sensor is provided on or associated with the other of the closure means or the housing portion, the magnetic switch arranged such that when the magnetic means or member is moved a pre-determined distance towards the magnetic sensor, the switch is moved to the on position, and when the magnetic means or member is moved a pre-determined distance away from the magnetic sensor, the switch is moved to the off position. 
     
     
         12 . The dispensing nozzle assembly according to  claim 1  wherein the switch is in wired or wireless communication with control means for controlling one or more operations conditions relating to the dispensing nozzle assembly. 
     
     
         13 . A method of using a dispensing nozzle assembly, the dispensing nozzle assembly including:
 a nozzle member provided with one or more dispensing apertures to allow fluid to be dispensed therefrom in use; said method including the steps of:   moving closure means provided on or associated with the nozzle member relative thereto between a closed position, wherein the closure means closes the dispensing apertures and fluid cannot be dispensed from the dispensing apertures, and an open position, wherein the closure means are moved at least partially clear of the dispensing apertures and fluid can be dispensed through the dispensing apertures in use;   moving switch means between an “on” position for allowing fluid to flow into the nozzle member for dispensing through the dispensing apertures in use, and an “off” position for preventing fluid flowing into the nozzle member in use;   characterised in that:   the switch means are arranged such that movement of the closure means relative to the nozzle member moves or actuates the switch means between the on and off positions.   
     
     
         14 . An actuator assembly for allowing fluid to flow from a fluid source to a dispensing nozzle assembly in use, said actuator assembly including actuator valve means movable between a closed position, wherein the actuator valve means engages with an actuator valve seat and fluid is prevented from flowing through the actuator valve means towards a dispensing nozzle assembly, and an open position, wherein the actuator valve means is moved a spaced distance apart from the actuator valve seat and fluid can flow through or around the actuator valve means in use towards a dispensing nozzle assembly, said actuator assembly further including plunger means for moving the actuator valve means between the open and closed positions in use, and solenoid means for driving movement of the plunger means in use, the solenoid means including a movable solenoid member, characterised in that the movable solenoid member and the plunger means are arranged such that they undergo parallel or substantially parallel movement in moving the actuator valve means between the open and closed positions.
