Claims

[Scope of utility model registration request]

Cooling of the engine combustion chamber formed by the cylinder head, the cylinder block superimposed on the cylinder head, and the piston sliding inside the engine cylinder of the cylinder block is separated between the cylinder head side and the cylinder block side. In order to achieve this, an upper oil circulation system that lubricates the cylinder head side and a lower oil circulation system that lubricates the cylinder block side are provided separately. and an oil jacket formed above the oil gear and around the engine cylinder to hold cooling oil,
A pressure regulating check valve is provided on the bottom of the oil jacket to inject pressurized oil from the oil gear toward the oil jacket, and the check valve is connected to a valve body having an oil spout formed in its side wall. and a valve mounting flange protruding from the lower part of the valve body, the valve body being configured such that the oil spout of the valve body faces the oil jacket side when the check valve is installed. An engine cooling device characterized in that a relative positional relationship between a flange portion and an oil spout is set.
