Abstract

A hydraulic rotary manifold has a core manifold having a barrel and a rotatable spindle inserted in the barrel. The core manifold is common to a variety of different configurations involving removable spindle-mounted and barrel-mounted manifolds, which may be removably mounted on the core manifold and exchanged for other removable manifolds to provide different hydraulic fluid flow paths in the rotary manifold using the common core manifold. The rotary manifold permits retrofitting a secondary fluid flow path to use a secondary fluid in conjunction with a work tool mounted on the rotary manifold. The rotary manifold permits mounting a rotary position encoder on a barrel-side of the rotary manifold permitting the use of the common core manifold when a rotary position encoder is desired. Electronically actuated cartridge valves may be integrated into the core manifold and/or removable manifolds to provide further customization of the hydraulic fluid flow paths in the rotary manifold and/or to provide cross-over relief paths within the rotary manifold itself.
