Abstract
A low friction fluid motor has a diaphragm mounted in a shell to divide the shell into first and second chambers, a port means for connecting the second chamber to a pressure or vacuum source, and an actuator assembly. The actuator assembly is connected to the diaphragm and includes an actuator member extending out of the shell through an aperture. The actuator is free of any seal member which is interposed between the actuator member and the shell and which functions to form a seal between the actuator member and the aperture in the shell. The aperture is oversized relative to the actuator member to allow free passage of the actuator member from the actuator assembly through the first chamber and out of the fluid motor.
