Removable reservoir cover having internal parts of reservoir mounted

Abstract

A detachable cover member for use with a reservoir for hydraulic fluid such as oil in which the various components associated with the reservoir are rigidly mounted on the cover member and are removed from the reservoir tank when the cover is removed. Thus, the suction conduit and the return conduit extend through and are both rigidly secured, as by welding, to the detachable cover member. The respective suction and return conduits are adapted to extend down into the interior of the reservoir tank when the cover member is secured in overlying relation to the cover-receiving opening of the reservoir. A baffle member is rigidly secured to the normally inner surface of the cover member in a plane substantially perpendicular to the inner surface of the cover to divide the interior of the reservoir into suction and return chambers, the baffle being so constructed as to permit fluid communication between the two chambers. Each of the respective suction and return conduits extends from its respective rigid connection to the cover member through the baffle member, each respective conduit being rigidly connected as by welding to the baffle to provide a reinforced construction for the cover subassembly. A ' breather' device is rigidly mounted on the normally outer surface of the cover member and is in gaseous communication with the interior of the upper end of the reservoir to maintain atmospheric pressure above the liquid level in the reservoir tank. A combined fill tube and dip stick holder are also rigidly mounted on the detachable cover member. Thus, when the detachable cover member is removed from the reservoir, all of the aforementioned components are removed along with the cover.
