HYDRAULIC TANK FILL SYSTEM

摘要

A hydraulic tank fill system for a machine includes a tank, a valve operatively coupled to the tank, and a supply line in communication with the valve and the tank. The supply line supplies a fluid into the tank from a fluid source. A breather device installed on a top portion of the tank exerts a pressure on the fluid in the tank for controlling at least one of an operating pressure associated with the tank. A vent line in communication with the valve and the top portion of the tank to receive an excess quantity of the fluid based on the exertion of pressure on the fluid in the tank. An orifice disposed in the vent line exerts a back pressure on the excess quantity of the fluid received into the vent line.
