The vane actuator according to the present invention is capable of operating effectively at a working pressure greater than 100 psig. The vane actuator comprises a vane shaft rotatably extending through a casing and a vane disposed within the casing defining a first pressure chamber and a second pressure chamber therein. The casing includes stiffening members for resisting deflection of and maintaining an internal seal within the casing when exposed to a pressure of 150 psig. The stiffening member may be located in the range of about 10.degree. and 20.de...
[ What is claimed is:] [1.]1. A clam shell shaped vane actuator, said actuator comprising:a top case having a top surface comprising a top stiffener, wherein an outermost edge of said top stiffener extends no more than about 20.degree. on either side of a center line of positioned along a central region of said top surface to resist deflection thereof, said top case including an top central section for receiving a vane, and including an upper bore for rotatably receiving a vane shaft;a bottom case having a lower surface comprising a bottom stiffener, whe...
