齿轮分流器是由彼此间具有刚性运动约束的两对 或两对以上齿轮啮合组所构成的，用于分流或集流的可逆式液压元件。刚性运动的约束可保证流经各齿轮组件的工作液流量的比例关系按其各自的排量，而且不受分支油路压力的影响，而且当其中一个或几个齿轮组件出口处的压力降低时，还 Gear splitter consists of two or more than two pairs of gear meshing groups with rigid motion restraint between each other, which are used to divert or collect reversible hydraulic components. The rigid motion constraint ensures that the flow rates of working fluid flowing through each gear assembly are proportional to their respective displacement and are not affected by the pressure of the branch lines and that when the pressure at the outlet of one or more of the gear assemblies decreases ,also
