Abstract
An oral irrigator has a pump, a discharge nozzle and a pressure control. The pump has a generally constant operating speed and feeds the discharge nozzle. The pressure control is adapted to modify a discharge pressure at the nozzle without a significant change in pump speed. The pressure control modifies a level of fluid flow restriction between the pump and the nozzle. The modification of the level of fluid flow restriction is accomplished by modifying aspects of a fluid flow path extending through the pressure control. The aspects modified include the diameter, length and/or number of direction changes of the fluid flow path.
