  • Hydraulic oil cooler and supplying vessel pressure stabilizer
    Patent number: 6732791
    Abstract: A fluid delivery system, for e.g. a vehicle, includes a tank for holding fluid product, such as propane, a pump for pumping the fluid product from the tank, the pump being driven by hydraulic fluid, and a heat exchanger for using the fluid product to cool the hydraulic fluid. The heat exchanger also causes the fluid product to increase in temperature. The heated fluid product is returned to the tank, in the form of a vapor, for example. Embodiments of the invention provide a number of advantages, including increased pump flow rates, reduced cavitation, increased pump life, and elimination of a heat-exchanger fan.
    Type: Grant

    Date of Patent: May 11, 2004
    Assignee: STAC, Inc.
    Inventors: John Buysse, Rick Story
  • Engine fluid cooling systems and methods
    Patent number: 6497202
    Abstract: A portable, self-contained apparatus for cooling automotive engine fluid, e.g. engine coolant, includes quick couplers for connection to an automotive engine. The apparatus receives hot engine fluid from the engine, cools the engine fluid, and returns the cooled engine fluid to the engine. A fluid reservoir and one or more heat exchangers aid in the cooling process. Corresponding methods provide similar advantages.
