Abstract

PURPOSE: To devise to alarm a driver as soon as oil pressure is abnormally lowered by taking a signal from the connecting point of an oil pressure gauge and an oil pressure sensor and providing an alarming circuit to operate an alarm when oil pressure is abnormally lowered.
CONSTITUTION: The connecting point of an oil pressure gauge 4 and an oil pressure sensor 5 is connected with an input signal terminal 8 of an alarming circuit 6. When the pressure of lubricating oil is low, a contact 20 is kept opened, and consequently, the voltage at the input terminal 8 is equal with the voltage of an electric source to keep a transitor 11 off. A transistor 15, therefore, is off without the supply of base current. Since the "off" of this transistor permits the supply of the base current to another transistor 17 through a resistance 16, the transistor 17 is on to light an alarm lamp 7. In this construction, when oil pressure is abnormally lowered during running, a driver can be informed of the abnormality.
