Abstract
A tank assembly stores hydraulic oil in a system for actuating hydraulically operated cylinders, specifically on Class VI, VII and VIII trucks. A pump draws the fluid from the tank to force the hydraulic cylinder to an upright position. When the pump valve is shifted to the down position, the hydraulic fluid is returned to the storage tank at a reduced velocity without the reduction of the rate of flow in gallons per minute below the rated pump capacity, thus preventing the aeration of the fluid. An attachment kit includes grooves in the top of the tank-receiving nylon belts with loops at their ends receiving U-bolts for attaching to flanges of a tray, for mounting on a truck.
Claims8
A tank assembly comprising a rotationally molded polyethylene material tank, comprising a rectangular shape, further comprising indentations in the tank for reinforcing the tank against distortion and for guiding alignment guides, a carriage base adjacent the tank, retaining straps in the guides for attachment of the tank to the carriage base, U-bolt attachments at ends of the retaining straps and extending through holes in the carriage base;
- further comprising two port openings having two metallic port fittings molded into the polyethylene material of the tank for forming a component part of leak proof compression seals;
- further comprising a filler/breather assembly at a top of the tank;
- further comprising a filter/diffuser connected to one of the port fittings for retarding returning fluid velocity without reducing flow in gallons per minute;
- further comprising a chassis attachment kit connected to the carriage base for mounting the carriage base and the tank assembly, further providing a crowning of both sides of the tank between the indentations for providing reinforcement and for resisting distortion caused by occasional heat build up;
- further providing, for attachment to the two metallic port fittings molded in the polyethylene material, two externally attached compression nuts to provide said leak proof compression seals;
- the two port fittings and the nuts being adaptable for an installer/user plumbing arrangement and to allow external installation and sealing of said filter/diffuser in either port opening.
A wet tank assembly suitable for packaging and transportation and resistance to distortion, comprising a tank having dual screw-in ports;
- an externally mounted, screw-in filter/diffuser connected to one of the ports, a filler/breather assembly connected to the tank for providing passage of air into and out of the tank;
- attachment straps, circumferential indentations on the tank for providing reinforcement, as well as for serving to guide the attachment straps, corresponding U-bolts attached to ends of the straps, a carriage base, through holes provided in the carriage base for receiving the U-bolts;
- further comprising a chassis attachment kit consisting of four pre-punched mounting angles, four mounting pads, four cap screws, four lock nuts, four compression springs;
- all prepackaged into a single shipping carton, which consists of one corrugated carton;
- this complete tank assembly with corresponding carton providing shipment of complete product by parcel service;
- further the tank assembly dimensions do not exceed 130" girth and length.
