  • Central hydraulic system for marine deck equipment
    Patent number: 3934416
    Abstract: In a central hydraulic system for marine deck machinery, fixed displacement hydraulic motors are utilized to drive anchor winches and standard mooring winches, and variable displacement hydraulic motors are utilized to drive automatic mooring winches. This permits individual regulation of the line pull or tension of the mooring line of each automatic mooring winch. Variable displacement pressure compensated over center pumps are utilized to supply hydraulic fluid for operating the hydraulic motors by means of a closed loop circuit, and charging pumps are utilized to supply hydraulic fluid at charging pressure.Infinitely variable volume pressure compensated pilot operated four-way directional valves are used to regulate the flow of hydraulic fluid from the variable displacement pressure compensated over center pumps to the hydraulic motors, thereby regulating the speed of operation of each hydraulic motor and the marine deck winch driven thereby.
