A motor is operatively connected to said first and second actuator. A circuit is connected to said motor, as well as a sensor assembly and a power supply. In operation, said first and second actuator moves a stem valve and a cylindrical pump located on a reservoir containing a gel soap and an inert propellant gas. The cylindrical pump operates on a piston principle and also closes to prevent any dripping after use. Further disclosed are various methods of accurately dispensing a consistent dose of gel soap.

Abstract: A fluid dispensing apparatus includes a pulse generator coupled to a pump that operates in discrete cycles. Each cycle includes a first part in which fluid is drawn into the pump through an inlet, and a second part in which fluid is expelled from the pump through an outlet. Each cycle results in a discrete, consistent volume of fluid being expelled. The pulse generator transmits discrete pulses to the pump, causing the pump to operate for a set number of cycles per pulse. The total number of cycles is a multiple of the number of pulses transmitted, so that the number of pulses determines the volume of fluid dispensed. Alternatively, the pump is driven through increments of the second part of the cycle, with the number of pulses supplied to the pump determining the proportion of the second part of the cycle completed, and therefore the volume of fluid dispensed.
