Abstract
A pump used in a power toothbrush for fluid delivery to the bristles. The pump moves fluid provided to it to a dispensing valve located in the brushhead. The pump includes a pump chamber with a piston ball located therein. The piston ball moves within the chamber in response to movement of the brushhead, moving fluid out a discharge end of the pump chamber under pressure. The pump includes a fluid exit channel which connects the discharge end of the pump chamber with an opening in the brushhead in which the dispensing valve is located.
