ABSTRACT:
A fluid power device such, for example, as one for opening and closing clam shell gates is operated by a ram under fluid pressure. A tank is provided for storing fluid under pressure and by a system of valving extension of the ram, as for a gate opening operation, is inhibited until enough fluid under pressure is stored in the tank to assure completion of reverse operation of the ram to close the gates.
