초록

A valve actuator with an arcuate piston disposed within a housing including a side wall having a partition and two end plates whereby when joined, the housing forms a first and a second compartment. An arcuate piston travels between the compartments via an opening in the partition in an oscillating manner. A removable piston assembly enables removing the arcuate piston, output shaft and lever arms supporting the piston in order to remove the output shaft or to engage a spiral spring connecting the output shaft with the housing. The spiral spring may be p...
