Abstract
This hydraulic apparatus for body care, notably buccal care, and for supplying a liquid to a hand appliance, comprises a casing enclosing a pump and power means for driving the pump. The pump input is connected via a valved coupling to the bottom of the detachable reservoir containing the liquid, and the pump output is connected via a hose to the hand appliance. The valved coupling comprises a movable valve member having a flat annular valve surface adapted to engage a registering flat annular seat consisting of the marginal portion of an opening formed in the bottom of the reservoir, when the latter is removed from the casing. Spring means constantly urge the valve member to its seated position.
