ABSTRACT:
A hydraulic system for working cylinders of construction equipment is disclosed. The system allows oil to be smoothly drained from a chamber of a working cylinder into an oil tank through a first passage or/and a second passage without being resisted during an operation of the cylinder. The system thus effectively and smoothly moves the working cylinder while improving operational efficiency and operational speed of the cylinder. When the system is used with a boom cylinder of a power excavator, the system effectively performs a boom-up or boom-down action without losing pressure.
