HYDRAULIC BOOSTING DEVICE CAPABLE OF MAXIMIZING BOOSTING EFFICIENCY

摘要

PURPOSE: A hydraulic boosting device is provided to accomplish multi-step boosting by forming an inner fluid path through dividing of a compact body and by installing a plurality of boosting valves on the inner fluid path.;CONSTITUTION: A hydraulic boosting device comprises an upper body(100), a middle body(200), a lower body(300) and a bolt(400). The upper body comprises a hydraulic support hole(11) and a recovering hole(12). The lower body comprises a discharge hole, which boosts fluid pressure and discharges. A fluid path for supplying and recovering fluid is formed in the upper, middle and lower bodies. A boosting valve of at least one check valve type is installed on the fluid path. The pressure of fluid supplied through the supply hole gradually rises through the booting valve and is discharged to the discharge hole.;COPYRIGHT KIPO 2012
