具有基于优先级共享的闭环液压系统
Abstract:
公开一种具有第一、第二和第三泵的液压系统(72)。该液压系统还可具有以闭环方式连接到第一泵的第一致动器(26)、以闭环方式连接到第二泵的第二致动器(32)和第三致动器(34)。液压系统可进一步具有与第三泵相关的选择阀(122)和与第三泵和第三致动器相关的第一转换阀(121)。第一转换阀能够在第三泵以闭环方式连接到第三致动器以使第三致动器在第一方向上运动的第一位置、第三泵以闭环方式连接到第三致动器以使第三致动器在第二方向上运动的第二位置和第三泵连接到选择阀的第三位置之间运动。
Abstract(English):

A hydraulic system is disclosed having first, second, and third pumps. The hydraulic system may also have a first actuator connected to the first pump in closed-loop manner, a second actuator connected to the second pump in closed-loop manner, and a third actuator. The hydraulic system may further have a selector valve associated with the third pump, and a first switching valve associated with the third pump and the third actuator. The first switching valve may be movable between a first position at which the third pump is connected to the third actuator in a closed-loop manner to move the third actuator in a first direction, a second position at which the third pump is connected to the third actuator in a closed-loop manner to move the third actuator in a second direction, and a third position at which the third pump is connected to the selector valve.
