초록

A rotary actuator having a cylindrical housing in which an annular piston arm rotates through an arc within an annular chamber in the housing as a result of fluid pressure to produce rotary motion communicated from the piston to the drive shaft. The piston head is capable of lateral or radial movement relative to the piston arm so as to accommodate flexing of the piston arm or variances in the shape of the chamber. Friction reduction washers are placed between the piston head and the piston arm to facilitate this movement. The overall effect is to reduce...

청구항

In a double acting, fluid driven rotary actuator having a housing and an annular chamber within said housing, the improvement comprising a single piston arm and attached piston head rotatable in either direction coaxially within said annular chamber, means for introducing a fluid pressure fore and aft of said piston head, and attachment means for attaching said piston head to said piston arm such that said piston head can move laterally relative to said piston arm and such that said piston head can move axially relative to said piston arm between first a...
