ルポンプ付き動弁装置。 In an engine valve train, a pump cam for driving a plunger is provided on the outer periphery of one end of a camshaft, a plunger is driven by the pump cam, and the plunger is fitted to allow reciprocating sliding of the plunger. an oil chamber formed in the cylinder head; a spring loaded in the oil chamber to bias the plunger toward the pump cam;
An inlet oil passage and an outlet oil passage connected to the oil chamber, an inflow check valve that is interposed in the inlet oil passage and only allows lubricating oil to flow into the oil chamber, and the outlet An outflow side check valve is installed in the side oil passage and allows only the outflow of lubricating oil from the oil chamber, and as the plunger driven by the pump cam reciprocates within the oil chamber. A valve train equipped with an oil pump, comprising an oil pump that pumps lubricating oil from the inlet oil passage to the outlet oil passage.
