摘要: A locking pneumatic piston (100) is provided. The locking pneumatic piston (100) includes a piston rod (113) connected to a piston (120) located in a piston chamber (103) and extending out of the piston chamber (103). The locking pneumatic piston (100) further includes a locking seal (124) extending around and positioned at a circumferential surface (126) of the piston (120) and an internal pneumatic channel (127) extending through at least a lengthwise portion of the piston rod (113) and through the piston (120) to the locking seal (124). When a pneumatic locking pressure is provided to the internal pneumatic channel (127), the pneumatic locking pressure extends the locking seal (124) at least partially outward and away from the piston (120) and presses against the inner surface (104) of the piston chamber (103), substantially locking the piston (120) in place within the piston chamber (103).
