FIELD: machine building.
SUBSTANCE: exemplary device includes an actuator housing having a loading device defining an upper pressure chamber and a lower pressure chamber. Upper pressure chamber is located opposite the lower pressure chamber. Cross-beam serves to connect the actuator body to the hydraulic valve. In the cross member body inner channel is formed for fluid communication of the control fluid with at least one of the two chambers, an upper or lower pressure chambers. Fluid connection assembly is disposed in the actuator housing for the internal channel with the upper pressure chamber fluid communication. Loading device is located between the cross-member inner channel and the upper pressure chamber.
EFFECT: presented are actuators having internal channels.
