PROBLEM TO BE SOLVED: To provide a leg ascending and descending electric hydraulic actuator system for ascending and descending legs of an airplane in which an occupation space of a leg ascending and descending electric hydraulic actuator system is reduced to the minimum while securing the redundancy of hydraulic pressure supply sources, and the weight thereof is reduced.SOLUTION: A leg ascending and descending electric hydraulic actuator system 1 includes a plurality of hydraulic actuators 21, 22 and 23, one hydraulic pump 33 and one electric motor 34, and also comprises a plurality of hydraulic pressure supply sources 31 and 32 which are arranged in parallel with each other. At a normal time, the plurality of respective hydraulic pressure supply sources sequentially supply operation fluids to the plurality of hydraulic actuators. When one of the plurality of hydraulic pressure supply sources is failed, the hydraulic pressure supply source other than the failed hydraulic pressure supply source sequentially supplies the operation fluids to the plurality of hydraulic actuators. |

PROBLEM TO BE SOLVED: To provide a hydraulic system for an aircraft actuator which drives an actuator even when a loss or reduction in the function of an aircraft hydraulic power source occurs, and which suppresses an increase in the overall temperature of the system and in the temperature of an oil used.SOLUTION: The hydraulic system includes: an electric motor 19, which drives a variable capacity backup hydraulic pump 18 that can supply pressure oil to an actuator 14 when a loss or reduction occurs in the function of an aircraft central hydraulic power source 104; a power source unit 20 which rectifies electric power supplied from a variable frequency supply 108; and a driver 21 which supplies the electric power from the power source unit 20 and drives the electric motor 19 so as to rotate the pump 18 at a predetermined constant rotational speed. The constant rotational speed is set, based on the change in the efficiency of each of the pump 18, the electric motor 19, and the driver 21 with respect to the rotational speed of the pump so as to maximize the overall efficiency obtained as a product of these efficiencies. |

PROBLEM TO BE SOLVED: To provide an actuator free from defects found in a conventional actuator.
SOLUTION: This actuator comprises main bodies 1, 2, 3 having cylindrical cavities, a rod 4 penetrated through an end part of one of the cavities, and an additional means for advancing the rod. The additional means has a means for preventing the rotation of the rod 4 to the main body of the actuator, a nut 8 firmly fixed to the rod, a screw 8 axially extended inside of the cavity and cooperated with the nut 7, a driving shaft 9 axially extended inside of the cavity and freely rotatable, and a rotation driving means 13 for driving the driving shaft 9. The screw 8 is mounted slidably but irrotationally along the driving shaft.

PROBLEM TO BE SOLVED: To provide a fluid control valve of compound function which can show different function according to applied pressure with a small-sized simple structure. SOLUTION: A spool 32 is provided with a part 33 driven according to input, and a movable valve element 34 displaceably supported thereto, for opening/ closing changing over fluid passages 31b to 31e. A pressure sensing chamber is arranged between a housing 31 and the spool 32 for energizing a movable valve body 34 to a normal function operation position on one side of a valve element displacement, due to hydraulic pressure. A spring 38 is arranged between the movable valve body 34 and the driven part 33 for energizing the movable valve element to the other side. When the hydraulic pressure in the pressure sensing chamber 37 is reduced, the movable valve body 34 is moved to the functional operation position on the other side in the displacing direction of the valve element. |
