Title: Rotary pneumatic actuator
Inventor: BAUMANN HANS D
IPC: F15B15/10
Filed: 2003-03-14
Abstract: A method and apparatus for translating linear movement into rotational movement in an actuator configuration is provided. For example, a rotary actuator assembly includes a housing having a central bore. A piston is disposed within the housing and is linearly movable along an axis of the central bore. A rolling diaphragm is disposed within the housing and coupled with the piston. A bifurcated linkage having an end flange couples with the piston and the rolling diaphragm. An articulatable coupling further connects the bifurcated linkage with a rotating linkage. A  spring button, which can be cone shaped, is disposed within the housing. A  compression spring is retained between the end flange of the bifurcated linkage and the spring button, for example, by a threaded rod and nut. The assembly is arranged such that when force is applied to the rolling diaphragm the bifurcated linkage is linearly transported; which results in the pivoting of the rotating linkage about a pivot point. The pivot point can couple to a valve stem to control a valve.
