Abstract: Fluid dispensing apparatus for dispensing preselected quantities of fluid from a supply of fluid under pressure having a flow regulator and a dispenser. The flow regulator is adapted to be coupled to the fluid supply so that fluid is supplied to the dispenser at a relatively constant pressure below the fluid supply pressure. The dispenser has a valve and a solenoid actuator which is energized to open the valve to permit fluid flow through the dispenser. A timing circuit in the dispenser energizes the solenoid actuator for a predetermined interval upon energization of the timing circuit. A size selector assembly coupled to the timing circuit enables the predetermined interval and therefore the quantity of fluid dispensed to be preselected from a plurality of possible quantities. The preselected predetermined interval may be varied to change the selected size or quantity of fluid to be dispensed.
