  • Publication number: 20200283995
    Abstract: An electro-hydraulic arrangement for controlling operation of a pair of tilt actuators of an earthmoving machine includes a housing, and a directional control valve (DCV) and a regeneration valve (RV) disposed within the housing. The DCV and the RV are coupled in selective fluid communication with one another and with rod end and head end chambers of the actuators via ports defined on the housing. When the DCV is in a first or second operative position, the RV may be positioned in a regenerative position to allow the rod end chambers of respective ones of the first and second actuators to communicate fluid to the head end chamber of the second actuator. Optionally, the regeneration valve may be positioned in a drain position to allow the rod end chambers of respective ones of the first and second actuators to communicate fluid with a drain port of the housing.
