ABSTRACT:
A liquid discharge device using a peristaltic pump having a depression and delivery system including an elastic tube for introducing compressed air into a liquid reservoir to be maintained in a selective pressurized state. A motor drive circuit is adjusted to vary motor rotation to sequentially squeeze and release one end of the elastic tube thereby varying the rate of pressurization in the reservoir.
