ELECTRO-HYDRAULIC ARRANGEMENT FOR AN EARTHMOVING MACHINE

An electro-hydraulic arrangement (310) for controlling operation of a pair of tilt actuators (112, 114) of an earthmoving machine (100) includes a housing (312), and a directional control valve (DCV) (314) and a regeneration valve (RV) (316 disposed within the housing (312). The DCV (314) and the RV...

Summary:An electro-hydraulic arrangement (310) for controlling operation of a pair of tilt actuators (112, 114) of an earthmoving machine (100) includes a housing (312), and a directional control valve (DCV) (314) and a regeneration valve (RV) (316 disposed within the housing (312). The DCV (314) and the RV are coupled in selective fluid communication with one another and with rod end and head end chambers (116, 118) of the actuators via ports defined on the housing (312). When the DCV (314) is in a first or second operative position, the RV may be positioned in a regenerative position to allow the rod end chambers (116) of respective ones of the first and second actuators (112, 114) to communicate fluid to the head end chamber (118) of the second actuator (114). Optionally, the regen valve may be positioned in a drain position to allow the rod end chambers (116) of respective ones of the first and second actuators (112, 114) to communicate fluid with the drain port (346) of the housing (312). 一种用于控制土方机器(100)的一对倾斜致动器
