Claims

[Scope of utility model registration request]

A pressure feeding type lubricating device A is installed in the engine E, and the supply port 3 at the tip of the lubricant oil guide path 7 is opened toward the valve shaft 2 of the intake and exhaust valve 1 of the engine, and the starting end 7a of the oil guide path 7 is fed under pressure. A lubrication pump P of the pressure-feeding type lubrication device A communicates with a pressure-feeding oil passage 8 to the type-type lubrication device, and transfers the lubricating oil stored in the lubricating oil reservoir 4 of the engine E. In the engine intake/exhaust valve lubricating device configured such that the lubricating oil is supplied from the supply port 3 to the valve shaft 2 through the pressure oil passage 8 and the lubricating oil oil guiding passage 7, a temperature-sensitive operating valve 10 is attached to the oil guiding passage 7. The engine intake/exhaust valve lubricating device is characterized in that the temperature-sensitive operating valve 10 is configured to be able to open and close as the detected oil temperature increases and closes as the detected oil temperature decreases.
