Abstract
The invention provides an improved manifold assembly and hydraulic system for use in connecting hydraulic lines according to a predetermined circuit design. The invention is especially useful in a pilot control circuit for operating heavy equipment that is multifunctional or has the ability to operate multiple attachments. The manifold assembly comprises a baseplate having a plurality of inlet and outlet ports that are connected to various components in the hydraulic circuit. Connecting elements are then used to connect the designated inlet and outlet ports. In a preferred embodiment, the connecting elements include one or more channel plates attached to the baseplate that have segregated flow channels or passageways and interconnect the designated inlet and outlet ports. In order to convert the system from operation of one type of attachment to another, it is only necessary to exchange one set of designated channel plates for another. This provides ease and simplicity in the conversion from the use of one attachement to another.
