摘要： A rotary actuator includes an output shaft, a housing, a piston, and a friction reducer. The housing includes an arcuate bore that extends around the output shaft. The piston is coupled to the output shaft and moved in the arcuate bore. Pressure fluid acts to move the piston. The friction reducer is configured to reduce friction between a peripheral surface of the piston and an inner circumferential surface of the housing forming the arcuate bore.

摘要： A cylinder is installed within a case. An output shaft is installed in a hollow space within the cylinder. A pair of pistons extend in an arc, and is supported so as to be able to slide and be displaced along a circumferential direction of the cylinder within the cylinder. The pair of pistons is able to urge an arm integrated with the output shaft from two sides of the arm. Pressure chambers into which a pressure medium is introduced are defined between the cylinder and each piston in the pair of pistons. The pressure medium is fed to one of the pressure chambers and drained from the other, and thus the arm is displaced, and the output shaft pivots in a rotational direction.

摘要： Provided is a test apparatus for an actuator, which can easily switch whether to establish or undo the coupling between an actuator to be tested and a load part configured to apply load to the actuator. A test apparatus for an actuator includes a load part for outputting load to be applied to an actuator to be tested, first levers for swinging around a rotational shaft in connection with an output from the load part, an idler link coupled to the output from the actuator to be tested, a second lever coupled to the idler link in a swingable manner and for swinging around a rotational shaft that is arranged coaxially with the rotational shaft of the first levers, and a clutch mechanism for coupling together the first levers and the second lever and undoing the coupling.

摘要： A fluid valve has a valve plug configured as follows. In order to control a flow rate of a fluid between a first pressure chamber and a second pressure chamber, the valve plug is provided so as to be openable and closable in accordance with a difference between forces generated by pressures in the pressure chambers and resilience of an elastic member. The fluid valve includes an opening motion promoting portion. The opening motion promoting portion promotes an increase in degree of opening of the valve plug after the valve plug has been opened.

摘要： An aircraft hydraulic valve includes a housing, a check valve, a valve opening component, and an auxiliary hydraulic pressure supply mechanism. The housing includes a first port communicated with a first chamber of a hydraulic actuator, a second port communicated with a switch valve bypass-communicating a second chamber of the hydraulic actuator with the first chamber, and an oil channel connecting the first and second ports. The check valve interrupts oil flow from the first port to the second port. The valve opening component is configured to open the check valve with pilot pressure supplied from the second chamber. The auxiliary hydraulic pressure supply mechanism obtains hydraulic pressure, for opening the check valve, from a closed hydraulic pressure section, which is defined in the oil channel between the check valve and the first port.

摘要： A hydraulic actuator is adapted to drive a spoiler of a wing having a flap. When the hydraulic actuator drives the spoiler in an overlapping region where a driving range of the flap and a driving range of the spoiler overlap, an output suppressing structure suppress a drive output of the hydraulic actuator in the overlapping region to be less than that in a non-overlapping region other than the overlapping region.

Inside the cylinder, a first pressure chamber on the arm side and second pressure chambers on the piston head portion side are provided. Third pressure chambers are provided on both sides of the cylinder. A pressure medium is supplied to one of the first pressure chamber and the second pressure chamber and discharged from the other, and the output shaft pivots in a rotational direction.
