  • Patent number: 5971727
    Abstract: The present pump design with the elimination of a separate hydraulic fluid path from the cylinder dramatically improves the efficiency and pressure achieved by the pump by 15% as a result of reducing the number of chambers provided in the pump interior. It is, however, imperative for reasons not completely understood that in order for these efficiencies to be obtained that a reservoir of oil be located adjacent the main oil intake volume to ensure quick filling of the main oil intake volume as the piston cycles to its pressure stroke. This prevents cavitation of the pump.
