ンプ付き動弁装置。 In an engine valve train, there is a plunger-type pump drive swash plate provided in the form of a flange on the outer periphery of one end of a camshaft, a plunger driven by the swash plate, and a plunger driven by the plunger. an oil chamber formed in the cam cap or cylinder head to allow reciprocating sliding in the direction of the camshaft; a spring loaded in the oil chamber to urge the plunger toward the swash plate; an inlet oil passage and an outlet oil passage connected to the chamber; an inflow check valve that is interposed in the inlet oil passage and allows lubricating oil to flow only into the oil chamber; and an outlet oil passage. an outflow side check valve is installed in the passage and allows only the outflow of lubricating oil from the oil chamber, and as the plunger driven by the swash plate reciprocates within the oil chamber, A valve train equipped with a swash plate type oil pump, characterized in that a swash plate pump is configured to force-feed lubricating oil from the inlet side oil path to the outlet side oil path.
