Each piston includes an actuator extending downwardly from the piston and having a profile that, during a portion of the upward cycle of the piston, causes the actuator to push the member back into each intake channel to allow compressed fluid into each of the corresponding cylinders. Each piston includes a section that has a diameter that creates a seal against the corresponding cylinder during the upward cycle of the piston.

Abstract: In accordance with one embodiment of the present invention a pneumatic-operated toothbrush incorporates a pump that a user may utilize to pump are into and pressurize air in a reservoir. The reservoir is attached to a pneumatic motor, which utilizes the pressurized air inside the reservoir to rotate a drive shaft. Attached to the end of the drive shaft is a plurality of bristles that rotate when the drive shaft is rotating. The motor will continue to rotate the bristles as long as the pressure inside the reservoir is sufficient enough to force the air into the pneumatic motor. When the motor stops rotating the bristles, the user can pump air back inside the reservoir for continued use. It is important to note that the pneumatic toothbrush for the present invention is a self-contained device, meaning that the reservoir, motor and pump are incorporated into a single toothbrush. In addition the present invention does not use batteries or other electrical elements to power the motor.
