Patent ID: 7743740

Claim:
An automatic by-pass safety cooling system for a liquid cooled stationary internal combustion engine or for marine application of internal combustion engines, said engine having a primary cooling system including an engine jacket, a water cooled heat exchanger, coolant circulating between the jacket and the heat exchanger, and an independent supply of water to remove heat from the heat exchanger; said automatic by-pass safety cooling system comprising: a) valve means connecting said independent water supply to said heat exchanger; b) temperature sensing means located in said engine jacket for detecting the temperature of the engine coolant; and, c) control means for adjusting the pressure in said independent water system from 20 psi to 150 psi; d) solenoid drive means responsive to said temperature sensing means to automatically open said valve means at a pre-set temperature level thereby delivering water from the independent supply to said heat exchanger, said valve means being solely and directly actuated by said sensing means.
