Abstract

Improvements introduced in an automatic actuation device for valves, taps and the like having a ring-shaped cylinder tube that includes an outlet shaft, a ring-shaped cylinder tube whose central line describes a circular arc that surrounds said shaft. outlet, dividing walls dividing the actuation chamber formed inside said ring-shaped cylinder tube, pistons moving in said actuation chambers, and an annular piston rod that transforms the power of said pistons on a rotating power of said output shaft, the number of said dividing walls being 3 and the number of said pistons being two, said piston rod passing through two dividing walls, with the exception of at least the wall central partition, four actuation chambers being formed in said annular cylinder tube, and said piston rod c being onnected to said output shaft by means of a piston rod mounting bracket (Machine-translation by Google Translate, not legally binding)
