Adjustable valve for damping of oscillations, with an emergency operating device, uses battery as emergency power supply to bring valve to emergency operating position

The valve has a body with variable part, displaced by an electric servomotor (3) supplied from a primary electric source (11) and, in the case of failure of the primary source, from a secondary electric source (15). The secondary source is an electric battery, which is used to set (9) the valve to a...

More Information
Summary:The valve has a body with variable part, displaced by an electric servomotor (3) supplied from a primary electric source (11) and, in the case of failure of the primary source, from a secondary electric source (15). The secondary source is an electric battery, which is used to set (9) the valve to an emergency position. A diode (17) prevents current passing from secondary to primary source. L'invention concerne une valve réglable comportant un corps de valve (5) à position variable, en particulier pour un amortisseur d'oscillations, qui est déplacé jusque dans une position réglée définie de la valve et qui est maintenu par un servomoteur électrique (3) en association avec une alimentation en énergie. Le servomoteur électrique (3) est branché à une alimentation en énergie primaire (11) et à une alimentation en énergie secondaire (15), l'alimentation en énergie secondaire (15) étant utilisée en cas de défaillance de l'alimentation en énergie primaire (11).
