ABSTRACT:
A device for the precise replacement of liquids before, during, or after operation of a mechanism such as, for example, an automobile motor or automatic transmission, includes a housing and a piston or diaphragm for separation of the housing into inlet and exit portions. A plurality of bags can be employed in the housing for inlet and exit portions and as a diaphragm. Pressure from the volume of liquid in a closed vessel that is to be replaced is used to measure the amount of liquid replacing the liquid that is in the closed vessel. The device can be employed during normal operation of the mechanism, and a method for the precise replacement of liquids employs the device during normal operation of the mechanism.
