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.
