Abstract
An improved oil tank for storing hydraulic fluid and the hydraulically-powered system is fabricated from a polymeric material which is resistant to chemical breakdown from oil. The tank is constructed in a manner which facilitates internal circulation of hydraulic oil during use. The novel configuration of the tank lends itself to inexpensive fabrication through a rotational molding process. The tank is lightweight, inexpensive to manufacture, and is particularly advantageous for use in vehicle-mounted hydraulic drive systems.
