Claims

[Scope of utility model registration request]

Pressure oil from the oil pump is sent to the main gallery via the oil cooler and oil filter, while opening and closing according to the oil pressure on the main gallery side returns some of the pump discharged oil from before the oil cooler to the oil pan. In an engine oil pressure regulating device equipped with a pressure regulating valve, the pressure regulating valve has a main spool that opens and closes communication between the discharge passage and the return passage of the oil pump, and a spool that is attached in the closing direction to counteract the hydraulic pressure of the main gallery. a first spring that biases the piston, a piston that is slidable relative to the spool and opens and closes the return passage, and a second spring that biases the piston in the closing direction against the oil pump discharge pressure. An engine oil pressure regulating device characterized by comprising:
