ABSTRACT:
Alarm apparatus is provided for a recirculating exhaust gas flow control device, which device is employed in an internal combustion engine responsive to the negative pressure induced in the carburetor of the engine for controlling the flow of exhaust gas that is recirculated into the fuel-air mixture to be sucked into the engine; the device has a high pressure chamber in communication with the atmosphere, a low pressure chamber in communication with the engine negative intake pressure, and a diaphragm between the chambers for driving a valve that controls the flow of recirculating exhaust gas. The alarm apparatus employs a diaphragm forming high and low pressure chambers and for driving an actuating rod of a control circuit having an alarm signal lamp. The high pressure chamber of the alarm apparatus communicates with the low pressure chamber of the flow control device, and the low pressure chamber of the alarm apparatus communicates with the low pressure chamber of the flow control device and the engine intake, particularly within the vicinity of the carburetor. In the event that there is damage to the flow control device, admission of atmosphere into the high pressure chamber of the alarm apparatus through the control device drives the rod to actuate the alarm circuit.
