ABSTRACT:
A fluid power control system is disclosed which is characterized by a construction which provides for utilization of very basic fluid power flow elements and pilot signal elements to form a vast multitude of power flow control functions using a minimum number of standardized valving elements. The control system comprises a power flow manifold which serves to interconnect a plurality of pilot actuated power valving elements of a given power flow circuit arrangement which represents a multitude of potential circuit flow paths for switching and modulating requirements. The power flow manifold is provided with a plurality of internal pilot flow passages communicating with key power flow circuit junctions and pilot ports of the power flow valving elements. The pilot flow passages are arranged such that each outlet in a given pattern in a preselected face of the power flow manifold. In the preferred embodiment, one or more signal flow manifolds may be interchangeably mounted in stacked array to the face carrying the pilot outlet ports. Each signal flow manifold is associated with a given pilot flow subcircuit and pilot valving elements which are communicated to the power flow circuit via axially extending pilot flow channels commonly provided in the pilot flow manifolds to perform a variety of power flow control functions.
