Abstract

"Perfeccionamientos en servomotores of fluid under pressure", characterized by understanding a body; a motor piston that divides the interior of said body into two departments, and a control valve for regulating the operation of the servomotor and comprising a first chamber connected to one of said departments and to a first source of fluid under pressure; a second camera connected to the second of said departments; the first and second chambers are separated by an element connected with the pressure, functionally connected to a valve actuating element; a third chamber connected to a second source supplying fluid at a pressure different from that of the fluid supplied by the first source, and a mobile valve assembly formed by the first valve that controls the communication between the first and second chambers, and a second valve coupled to the first, and which regulates the communication between the second and third chambers and, further, because the second valve is coupled to a flexible wall separating the third chamber from a fourth chamber communicating with said first chamber; the surface limited by the seats of the first and second valves, and the effective surface of the aforementioned flexible wall, are equal.
