ABSTRACT:
A fluid operated stepping motor comprising a cylinder housing having one or more fluid cylinders to alternately displace at least two cam engaging members when pressure from a pressure source is applied to one of the cylinders. The cam engaging members are diametrically opposed. A cam is secured relative to the cylinder housing and having a plurality of teeth asymmetrically disposed thereon, is also provided. Each tooth has a power profile surface and an idle profile surface. The power profile surface is slidingly engageable by one of the cam engaging members when pressure is applied to displace the said one cam engaging member axially whereby the power profile surface will cause relative rotational displacement between the cylinder housing and the cam.
