摘要： The present invention relates to a method for controlling a hydraulic pump of a wheel loader, and to this end, the present invention provides a method for controlling a hydraulic pump, capable of improving acceleration performance of the wheel loader by reducing a flow rate of the hydraulic pump when there is a request for improving the acceleration performance of the wheel loader in a situation in which an increase in injection amount of fuel is not allowed due to limits on fume production during a travel-combined acceleration of the wheel loader, and further, provides a method for sequentially controlling a pump flow rate which is a sequential control performed by firstly reducing a flow rate of a fan pump that is not directly related to the working machine, and then secondly reducing the flow rate of the pump of the working system which drives a working machine as necessary, thereby improving the acceleration performance of the wheel loader by reducing torque of the working system while minimally influencing working performance when the engine reaches a rating limit in a transition state.

摘要： Provided is a work machine using a hydraulic motor and an electric motor to drive a swing structure, the work machine being adapted to reduce fuel consumption in regions where swinging by the hydraulic motor is prone to deteriorate in efficiency, such as when an operating stroke of swinging is small. The work machine includes an engine, a hydraulic pump driven by the engine, a swing structure, an electric motor for driving the swing structure, a hydraulic motor for driving the swing structure, the hydraulic motor being driven by the hydraulic pump, and a swing control lever device that commands the swing structure to be driven. The work machine further includes a control device operates in either an electric swing mode in which the swing structure is driven mainly by torque of the electric motor or a hydraulic swing mode in which the swing structure is driven mainly by torque of the hydraulic motor, depending on an operating stroke of the control lever device and/or a swing speed of the swing structure.

摘要： A first actuator (14a) drives a control surface (103a) by being operated by supply of pressure oil from a first aircraft central hydraulic power source (104) including a first aircraft central hydraulic pump (104a) . A second actuator (14b) drives the control surface by being operated by supply of pressure oil from a second aircraft central hydraulic power source (105) including a second aircraft central hydraulic pump (105a) . A backup hydraulic pump (18) is installed inside a wing (102a) of the aircraft (100) and is provided so as to be able to supply pressure oil to the first actuator (14a) when a loss or degradation in a function of at least one of the first aircraft central hydraulic power source (104) and the second aircraft central hydraulic power source (105) occurs.

摘要： The present invention is to reduce the flow rate of pressure oil discharged from a main pump and returned to a tank when specific work is executed with an operation amount of an operating device being made small in the state in which an engine is kept at an idling speed. According to the present invention, there is provided a main controller (20) which is capable of controlling the speed of an engine (11) to a normal work speed at which a work implement such as a boom (4) can perform normal work and which controls the speed of the engine (11) to an idling speed serving as a speed lower than the normal work speed when an operating device has returned from an operating position to a neutral position. Configuration is made such that the main controller (20) performs a control process for bringing the speed of the engine (11) to a specific work speed serving as a speed higher than the idling speed but lower than the normal work speed, on detecting execution of the specific work which is performed with an operation amount of the operating device such as a boom operating device (16) being kept small in a state in which the speed of the engine (11) is kept at the idling speed.
