Therefore, when oil pressure shut-off switch is not the most by pressure detecting signal transmission extremely control
During unit 22 processed, control unit determines electromagnetic valve 18 normal switching-off, and piston cooling nozzle passes through
The closed procedure of electromagnetic valve 18 and be in normal oil blocked state (described normal oil blocked state make
Oil does not flow to the oil pipeline 14 for piston cooling nozzle).
On the contrary, when oil pressure shut-off switch is detecting oil in the oil pipeline 14 of piston cooling nozzle
When the pressure of flowing and general's detection signal transmission are to control unit 22, control unit 22 determines
Electromagnetic valve is made because of the fault of electromagnetic valve 18 (such as, owing to being stuck in the fault of open mode)
18 maintain open mode so that oil is flowing in the oil pipeline 14 of piston cooling nozzle.
When electromagnetic valve 18 is stuck in open mode due to fault, oil flow to piston cooling spray continuously
