ABSTRACT:
This invention provides a fluid system for exchanging used hydraulic fluid with fresh hydraulic fluid in an accessed hydraulic circuit. One particular application provides an exchange apparatus for exchanging fluids of the type found in motor vehicle hydraulic circuits. The exchange apparatus may utilize pressurized spent fluid flow as a fluid power medium to activate the auto-replenishing fluid exchanger system to replace the spent fluid with fresh fluid at equalized flow rates. Alternatively, the exchange apparatus may utilize pressurize fresh fluid as a fluid power medium to activate the exchange system. Additional power may be supplied by an external boost pump to supplement the flow of fluid.
