Original Abstract Submitted
This disclosure describes a modular hydraulic manifold for controlling an operation of a hydraulic actuator for an earthmoving machine. The manifold has a spool chamber and a load sensing passageway. The body also has a spool positioned axially within the spool chamber. The spool is spring-biased by an end cap. The module also has a pair of spool actuators that are located at a second end of the body and operable to axially displace the spool within the spool chamber. The pair of spool actuators are positioned in parallel and disposed adjacent to one another. The manifold also has an inlet chamber disposed parallel to the spool chamber and in selective fluid communication with the spool chamber via a spool supply passageway. The body includes openings on opposite sides that open directly to inlet and spool chambers of adjacent bodies to reduce passageway constriction within the hydraulic system.
