ABSTRACT:
The servomotor is constructed with a cylinder and a surrounding pressure tank with a construction formed of a plurality of radial grooves through which air can be throttled during an emergency closing of a valve. The constriction is formed with a flow resistance equivalent to a free cross-sectional area of not more than 0.02D.sup.2 ; D being the inside diameter of the cylinder. The spherical pressure tank may be secured about a cup-shaped cylinder to form the pressurized chamber while radial grooves in a flange of the cylinder form a constriction with a cover secured to the cylinder and spherical tank.
