摘要： PROBLEM TO BE SOLVED: To provide a water pressure driving apparatus having a water pressure cylinder driven by working water sent from a water pressure pump, which controls the water pressure pump and cylinder with small control operating force, and improves a control response property, and also maintains high operating performance of the water pressure cylinder by regularly monitoring water pressure leakage within the water pressure cylinder.
SOLUTION: The water pressure driving apparatus is provided so as to drive a load so that working water fed from the water pressure pump directly driven by a variable speed motor is applied to the water pressure cylinder. The water pressure driving apparatus comprises a piston stroke detector detecting a moved position of a piston of the water pressure cylinder, and a motor control device controlling running speed of the variable speed motor so that a discharged amount of the water pressure pump becomes equivalent to a discharged amount corresponding to a targeted piston speed of the water pressure cylinder on the basis of a detected value for the moved position of the piston.

摘要： PROBLEM TO BE SOLVED: To provide a hydraulic driver controlling speed driven by a hydraulic actuator so as to fluctuate it in accordance with fluctuation of load force acting on the hydraulic actuator and providing an optimal speed control to the fluctuation of the load. SOLUTION: This hydraulic driver is provided with a control part 19 controlling a rotational speed of an electric motor 4 so as to make an actual value V of speed driven by a piston rod 5A of a single rod cylinder 5 coincide with a desired value V1 of speed, and the desired value V1 of speed is set in a fluctuating correlation to the fluctuation of the load F acting on the piston rod 5A. By this, since the desired value V1 of speed is fluctuated and set in correlation to the fluctuated load force F when the load force F fluctuates and the actual value V of speed is controlled to coincide with the desired value V1 of speed, the speed V driven by the piston rod 5A can be controlled so as to fluctuate in accordance with the fluctuation of the load force F and the optimal speed control to the fluctuation of the load force F can be provided.

摘要： PURPOSE: To eliminate a trouble caused by the contamination of fluid, by engaging a feed screw with the piston of a cylinder, having two operating fluid pressure chambers, and driving the feed screw by an air motor controlled through a position sensor signal of a hydraulic actuator.
CONSTITUTION: A feed screw 6 is engaged with a piston 5, having two operating fluid pressure chambers 8, 9, in a cylinder 2. Then an air motor 1, being connected to the feed screw 6, is driven and controlled by a position sensor signal of a hydraulic actuator. In this way, fluid in each operating fluid pressure chamber 8, 9 of the cylinder 2 is allowed to independently flow only shuttling between said chamber and the hydraulic actuator respectively without causing any necessity for interposing a valve or the like in the half way, thus hardly causing any trouble due to the contamination of the fluid and generation of heat due to the friction of a flow of the fluid.
