HYDRAULIC CIRCUIT
Document Type and Number:
Japanese Patent JPS61105301
Kind Code:
A
Abstract:
57 A hydraulic circuit for actuating a first hydraulic motor (11.12) with an under pressure fluid, comprising an externally driven first hydraulic pump (1) for introduction of fluid into the circuit from an open reservoir (6) and a hydraulic accumulator (5) to keep the introduced body of under pressure fluid stand-by, the pressure in the accumulator being sufficient to actuate the first hydraulic motor. The circuit comprises a fluid pressure intensifier comprising a second hydraulic motor (3) and a second hydraulic pump (4) coupled therewith, wherein the second hydraulic pump (4) has a smaller swept volume than the second hydraulic motor (3), and the second hydraulic motor (3) is interconnected in a discharge pipe (7) connected to an outlet of the first hydraulic pump (11) and an outlet of the second hydraulic pump (4) is connected to an inlet of the hydraulic accumulator (5).In particular the ratio k of the swept volume of the second hydraulic motor (3) to the swept volume of the second hydraulic pump (4) is adjustable.
