Patent number: 6862973Abstract: In one embodiment a pneumatic motor is provided that includes an intake chamber in fluid communication with at least one intake channel. Each intake channel is further in fluid communication with a corresponding cylinder, which receives a piston that cycles upwardly and downwardly to rotate a motor axle. A member is placed in each intake channel to seal the corresponding cylinder from each intake channel when compressed fluid in the intake channel has a higher pressure then pressure in the corresponding cylinder. 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 an intermediate section that has an annular groove, a seal positioned in the groove that creates a fluid tight seal against the corresponding cylinder during the upward cycle of the piston.Type: GrantFiled: July 25, 2003Date of Patent: March 8, 2005Assignee: Rehco, LLCInventors: Jeffrey Rehkemper, Charles Hartlaub

Publication number: 20040163385Abstract: In one embodiment, a pneumatic power-supply assembly includes a refillable chamber having an interior capable for holding a pressurized fluid, a vent, and a fluid inlet. A pressure release mechanism within the chamber permits the pressure within the chamber to vent, when the pressure exceeds a predetermined optimum pressure. A pneumatic motor is mounted within the chamber and includes an inlet in fluid communication with the interior of the chamber. The pneumatic motor utilizes the pressurized fluid within the interior of the chamber to drive a gear rotatably attached to the pneumatic motor. In addition, the gear rotates an axle rotatably attached to the chamber such that the when the assembly is attached to a pneumatic operated device the rotatable axle may be used by the pneumatically operated device. In addition, a external pump is attached to the fluid inlet to continually recharge the chamber.Type: ApplicationFiled: February 24, 2003Publication date: August 26, 2004Applicant: Rehco, LLCInventors: Jeffrey Rehkemper, Ryan Kratz, Charles Hartlaub

Patent number: 6622333Abstract: 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.Type: GrantFiled: September 4, 2002Date of Patent: September 23, 2003Assignee: Rehco, LLCInventors: Steven Rehkemper, Jeffrey Rehkemper, Charles Hartlaub, Todd Hannon
