ABSTRACT:
A device for monitoring the output pressure of an automatic oil pump and for controlling the intermittent timing sequence of the oil pump in accordance with the output pressure. A pressure sensing switch monitors the oil injection pressure and an integral watchdog timer insures that the oil pump injection pressure reaches a saturation level before a predetermined timeout occurs.
