摘要： [PROBLEMS] A direct-action valve lifter having reduced number of parts and simple structure and capable of being switched to high lift and low lift. [MEANS FOR SOLVING PROBLEMS] The valve lifter is interposed between a cam and a valve stem. The cam (20) has a high lift cam (22) and low lift cams (24) integrated together, and the valve lifter (30) has a side lifter (32) slidingly in contact with a low lift cam, a center lifter (40) slidingly in contact with a high lift cam, and a hydraulic means (hydraulic path)(11b) for sliding the center lifter (40) in order to switch the amount of valve lift between two stages of high and low. A slit (33) for causing the high lift cam to strike at the air is provided at the top of a cylindrical lifter body so that the lifter body functions as the side lifter (32) having low lift cam sliding contact surfaces (32a). A hole (34) orthogonal to the slit (33) is provided in the lifter body, and the piston-type center lifter (40) slid by hydraulic pressure is provided in the hole (34). When the center lifter (40) is at a position corresponding (not corresponding) to the slit (33), it is a high (low) lift mode. In the valve lifter, the number of parts is reduced and the structure is simple, a dimentional tolerance required for each part is relaxed, and work for assembling each part is simplified.

摘要： PCT No. PCT/EP96/05777 Sec. 371 Date Jun. 30, 1998 Sec. 102(e) Date Jun. 30, 1998 PCT Filed Dec. 20, 1996 PCT Pub. No. WO97/28356 PCT Pub. Date Aug. 7, 1997A tappet for the valve drive of an internal combustion engine, includes a cup-shaped housing (1) and an insert which is arranged inside the housing (1) and has an outer sleeve (4), which bears upon the cylinder wall, and an inner guide tube (5). Displaceably guided in the guide tube (5) is a hydraulic clearance compensation element (7), with the insert forming with the cylinder wall (2) of the housing (1) an oil channel (17) which extends from a bottom-distant inlet opening (18) of the cylinder wall (2) to a port adjacent an oil chamber (13, 15) and neighboring the bottom (3). In accordance with the invention, the oil channel (19) on the insert is designed as a helical groove formed in the outer sleeve (4). When the tappet is secured against rotation inside the cylinder head bore and so arranged with inclined longitudinal axis that the port (20) is always at the highest point, hydraulic oil is prevented from flowing from the filling chamber (13, 15) into the oil channel (19) and thus is prevented from flowing out of the oil chamber (13, 15) when the internal combustion engine is shut down.

摘要： PURPOSE: The cup is hard ended in a heat treatment process and the inner part is unhardened in order to eliminate the processing of the cup. CONSTITUTION: A valve tappet actuated by the cam of an internal combustion engine is made up iron-metal materials, and comprises of a base(3) which closes the end of the shell(2), an inner part(6), and an oil chamber. On the exterior, the shell(2) has a peripheral groove(4) and, on the interior, it is provided with at least one bead(5,21). Disposed concentrically inside the cup(1) is an inner part(6) of which the casing(9) abuts the bead(5,21). An oil chamber is located between the casing(9) and the shell(2), and makes oil channels, and a hydraulic valve clearance compensating element (10) is guided in an axially movable manner inside the inner part (6).
