ABSTRACT:
The apparatus is an automatic changeover system for a vehicle exhaust ventilating pipe. The exhaust pipe on a vehicle is fed into a valve which changes its output to either the conventional vehicle mounted exhaust outlet pipe or a bypass pipe low on the chassis to which a ventilating hose can easily be attached. The activating arm of an electrical switch is located at the end of the bypass pipe where it is held down by the ventilating hose when the hose is installed. Thus, when the vehicle is moved and the ventilating hose pulled off, the switch arm is released, and the switch activates a powered activator which moves the valve to close the bypass and open the output to the exhaust outlet pipe for normal operation.
