FIELD: machine building.
SUBSTANCE: valve actuator system consists of actuator to displace actuator first rod. Note here that said actuator comprises body and control actuating element arranged therein and connected with said first rod. Note also that said control actuating component and body define the position of the first and second brake chambers. Note here that control fluid is forced into first brake chamber to displace control actuator in first direction. Note here that control fluid is forced into second brake chamber to displace control actuator in second direction, opposite the first one. Besides, it comprises feed rate variator connected with actuator. Note that said variator comprises a correction actuator and spring for engagement with said correction actuator to displace actuator first rod to preset position.
EFFECT: perfected design.
