Flushing of liquid circulation systems
First Claim
1. Apparatus for flushing debris from a liquid circulation system that includes a heat-generating unit and two heat-dissipating units, the apparatus comprising an inlet conduit for connection to a source of flushing liquid, a first branch conduit for attachment to a point on the system communicating with the heat-generating unit and a second and third branch conduit for attachment to points on the system each communicating with a heat-dissipating unit, and a drainage conduit;
- and valve means interconnecting such conduits and settable between at least three positions in each of which a flushing liquid is adapted to pass through the inlet conduit and one of the branch conduits and, after traversing a flow path in the system, reenter the apparatus through another branch conduit and finally leave the apparatus through the drainage conduit, the flow paths differing for different settings of the valve means, and including at least one flow path in which the liquid is adapted to pass through at least two of the units of the system.

Abstract
The invention comprises apparatus for flushing debris from a liquid circulation system such as the cooling system of a water-cooled vehicle. The apparatus includes an inlet conduit for flushing liquid, a series of branch conduits connected to points on the circulation system, a drainage conduit for used water, and a valve or series of valves settable between various positions dictating different flow paths for the flushing liquid through the conduits and the circulation system.
