VALVE FOR ALLOCATING AVAILABLE FLUID TO HIGH PRIORITY FUNCTIONS OF A HYDRAULIC SYSTEM
Abstract:
A hydraulic system (10) has high priority hydraulic functions (17,18,19) connected to a primary supply line (15) that receives pressurized fluid from a source and low priority hydraulic functions (20) connected to secondary supply line (16). A priority valve (28) couples the primary supply line to the secondary supply line. The priority valve detects when the source is unable to furnish enough pressurized fluid to satisfy the demands of all the high and low priority hydraulic functions. In that case the priority valve reduces or eliminates fluid flow between the primary and secondary supply lines.
Abstract(Chinese):

液压系统（10）具有连接到从源供应加压流体的主供应管线（15）的高优先级液压功能（17,18,19），以及连接到二次供应管线（16）的低优先级液压功能（20） 。 优先阀（28）将主供应管线连接到二次供应管线。 优先阀检测源何时不能提供足够的加压流体以满足所有高低优先级液压功能的要求。 在这种情况下，优先阀降低或消除主和辅助供应管线之间的流体流动。
