Abstract: A fluid power control apparatus which comprises the unique combination of a control housing including a cylindrically shaped core member mounted in a sealed relationship within a receptacle member. A plurality of grooves or recesses generated in the outer wall surface of the core member define selected fluid path connections in axial and circumferential directions to radial passages formed in the core and receptacle members to communicate valve elements in the core or receptacle members to one another and to external means in almost any selected manner. This combination forms in a relatively simple and dramatically compact manner any preselected simple or complex fluid control circuit in a single package.
