Abstract
The appliance includes a body (12) which includes a tank (22) for liquid. A pump/regulator assembly (18, 20) maintains pressure in the tank in the range of 70-120 psi. A valve, timer and controller (30, 31, 37) controls sequential bursts of liquid, with each burst having a duration of 0.02-2 seconds, with the total amount of liquid in a single cleansing event being less approximately 0.2 ml or less. A firing rate is such that successive bursts of liquid are separated by a controlled time when there is no liquid delivery.
