摘要： A method includes receiving pump cycle location data associated with a fluid power system. The fluid power system includes a plurality of pumps (including at least a first pump, a second pump, and a third pump). Based on the pump cycle location data having a first value, the method includes activating the first pump as a primary pump. Based on the pump cycle having a second value, the method includes activating the second pump as the primary pump. The method also includes activating the third pump as a secondary pump when the fluid power system is in a multiple-pump operating mode.

摘要： An electric motor drives a variable capacity backup hydraulic pump that can supply pressure oil to an actuator when a loss or reduction occurs in the function of an aircraft central hydraulic power source. A power source unit rectifies electric power supplied from a variable frequency supply. A driver supplies the electric power from the power source unit, and drives the electric motor so as to rotate the pump at a predetermined constant rotational speed. The constant rotational speed is set, based on the change in the efficiency of each of the pump, the electric motor, and the driver with respect to the rotational speed of the pump, such that the overall efficiency, obtained as a product of these efficiencies, has a maximum value.

摘要： A wing driving apparatus is made up of a flight controller part for generating a drive signal, first and second servo actuators, a first controller unit having a first drive circuit, and a second controller unit having a second drive circuit. The first controller unit includes a follower signal generator circuit for generating a follower signal. The second servo actuator includes a solenoid valve for invalidating a control to the second serve actuator based on the drive signal from the second drive circuit in response to the follower signal, whereby the second second servo actuator follows the steering wing when the first drive circuit is able to operate the first servo actuator to drive the steering wing.

摘要： A hydraulic valve apparatus is for controlling pressurized fluid flow to at least a pair of coupled hydraulic actuators in response to operator signals. The valve apparatus comprises a main body having main ports communicating selectively with a fluid supply and fluid return, body ports to communicate with the actuators, and a scavenge port to communicate with the return. Each actuator communicates with two control valves and one scavenge valve on the valve body to control fluid flow relative to the actuators. Control devices cooperate with the control and scavenge valves of each actuator so as to actuate the respective valves simultaneously. The control devices maintain the two related control valves in the same phase with respect to each other, but in an opposite phase to the respective scavenge valve. In an emergency, an appropriate valve actuating device switches the appropriate control valves from a normally open to a normally closed position, while simultaneously switching the related scavenge valve from a normally closed to a normally open position. This permits an operating cylinder to passively displace an inoperative cylinder to enable operation of the apparatus with one actuator only.
摘要翻译：液压阀装置用于根据操作者信号控制加压流体流到至少一对耦合的液压致动器。该阀装置包括：主体，其主要端口与流体供应和流体返回选择性地连通;主体端口，与致动器连通;以及清除口与返回物体连通。每个致动器与阀体上的两个控制阀和一个清除阀连通，以控制相对于致动器的流体流动。控制装置与每个致动器的控制和清除阀配合，以同时致动相应的阀。控制装置将两个相关的控制阀相对于彼此保持在相同的相位，但是与相应的清扫阀相反。在紧急情况下，适当的阀门致动装置将适当的控制阀从常开状态切换到常闭位置，同时将相关的清扫阀从正常关闭位置切换到常开位置。这允许操作气缸被动地移动不工作的气缸，以使得仅使用一个致动器的设备的操作。
