Abstract
A hydraulic actuator with dual pneumatic operation, used in hydroelectric power plants, specifically in the field of hydropneumatic units generating hydraulic pressure for the operation of intake valves of hydroelectric power plants. The hydropneumatic actuator () comprises a hydropneumatic block () featuring two pneumatic pumps (anda) fixed to the base (). This block accommodates the cup assembly (), within which resides a cylinder () housing the plunger guide (). The plunger guide () is attached to the shaft end (), which is securely and firmly fastened to the cup end () using a guide nut (). The hydraulic actuator () can be articulated by fitting the female eyelet () into the male eyelet (), both of which being secured by the pin ().
