弁潤滑装置。A pressure-feeding lubricating device A is provided in the engine E, and an oil filler port 5 is provided at the tip of the lubricating oil guide path 3 toward the intake and exhaust valve shaft 2 of the engine E.
is opened, the starting end 3a of the oil guide path 3 is communicated with the pressure feed oil path 4 of the pressure feed type lubrication device A, and the lubricant oil stored in the lubricant oil reservoir 24 of the engine E is pumped by the lubrication pump P of the pressure feed type lubrication device A. In an engine intake/exhaust valve lubricating system configured such that lubricating oil is supplied to the valve shaft 2 from a supply port 5 through an oil path 4 and a lubricating oil guide path 3, the starting end 3a of the oil guide path 3 is connected to a pressure-feeding type lubrication device A. Connected to an upstream portion of the pressure-feeding oil passage 4 led out from the discharge port 6 of the lubrication pump P near the discharge port 6 of the lubrication pump P;
A state in which an on-off valve 7 is interposed in the oil guide path 3, the on-off valve 7 is interlocked and connected to an engine starting operating tool 8 that is operated when starting the engine E, and the engine starting operating tool 8 is operated to the starting operating position S. Now, the on-off valve 7 is opened and the lubricating oil pumped from the lubricating pump P to the pressure oil passage 4 is supplied to the valve oil 2 of the intake and exhaust valve 1 from the supply port 5 through the oil guide passage 3, and Move the engine starting operation tool 8 to the operation position T for starting and canceling the engine.
In the state returned to , the on-off valve 7 is closed and the supply of lubricating oil forced from the lubrication pump P to the pressure oil passage 4 to the valve shaft 2 of the intake/exhaust valve 1 through the oil guide passage 3 is blocked. An engine intake/exhaust valve lubricating device characterized in that an opening/closing valve 7 can be controlled and driven by an engine starting operation tool 8 so as to achieve the following state.
