摘要： A cam roller pin is rotationally fixed and defines a pin axis around which a cam roller is configured to rotate and apply a load at a load zone at a radially outer and lower end of the pin. The pin includes a reservoir configured to receive lubricant for lubrication of the cam roller rotating on the pin, a first lubricant path extending radially inward from the reservoir, a second lubricant path extending from the first lubricant path to a second lubricant path outlet, and a third lubricant path extending from the first lubricant path to a third lubricant path outlet.

摘要： A double-flow hydraulic support element for a switchable finger lever of a valve train of an internal combustion engine is provided. A piston is arranged in an axial bore of the housing of the support element in an axially movable manner, and the piston includes a hollow cylindrical pressure part and a cup-shaped working part. A head of the pressure part is used as a support for the finger lever and projects beyond the housing edge, and an opening for the flow of a hydraulic medium is formed in the end face of the head. The housing has a first passage and a second passage axially spaced from the first passage for the hydraulic medium. The support element has a hydraulic play compensation device with a ball non-return valve for the finger lever. In order to achieve an optimal actuation of the coupling element, a sleeve which is closed on one side is inserted into the pressing part; the closed end of the sleeve reaches the region of an outer annular groove in a sealing manner below the dome-shaped head of the pressing part; a storage space for supplying the play compensation device with the hydraulic medium is formed radially within and axially outside of the sleeve, in the pressure part, and in the working part of the piston; the storage space is connected to the first passage in the housing via a passage opening in the working part; an actuation space formed between the sleeve and the pressure part of the piston for hydraulically supplying the coupling device is connected to the second passage in the housing via a radial passage opening in the pressure part; and the volume of the storage space is substantially greater than the volume of the actuation space.

摘要： A follower mechanism movable along an axis within a bore including an alignment groove. The follower mechanism includes a bucket with a cylindrical inner surface and a cylindrical outer surface, and a yoke positioned at least partially within the bucket, the yoke including a bottom wall and two opposed sidewalls depending upwardly therefrom, each sidewall defining a shaft aperture. A shaft with first and second ends is received in the shaft apertures, and a roller follower is rotatably received on the shaft such that a portion of the roller follower extends axially outwardly beyond the bucket.

摘要： In a hydraulic compensation element for the valve train of an internal combustion engine, with a circular cylindrical housing (32) that has, in its bore (35), an axially movable pressure piston (36) with a reservoir (37) for oil as a hydraulic medium, a sleeve-like deflection element for oil is arranged in the interior of the pressure piston (36). The oil can be introduced through a radial feed hole of the housing (32), a rising channel (42), and an end-side opening (46) of the deflection element into the reservoir (37) of the pressure piston (36). The deflection element is constructed as a circular cylindrical inner sleeve (40) that has, on one axial end, an oversize dimension relative to the inner diameter of the pressure piston (36), and the inner sleeve (40) is fixed in the pressure piston (36) with a positive and non-positive fit connection.

摘要： An internal combustion engine having a valve lifter assembly is disclosed. The internal combustion engine comprising an engine head having at least two wells adapted to receive at least one valve lifter, the at least one valve lifter includes a flat surface, at least one spacer installed within the engine head having a first surface, a hollow portion, and a second surface, the first surface is tapered with respect to a vertical axis of the at least one spacer, and a tie-bar plate for coupling the at least one spacer using head bolts. The at least one spacer and the at least one valve lifter are operatively arranged during operation in such a way that the flat surface of the at least one valve lifter faces the first surface of the at least one spacer to prevent rotation of the at least one valve lifter.

摘要： The invention relates to a locking device for a switchable valve drive component, including a first locking body and a second locking body which can be brought into engagement with one another or out of engagement in order to couple to one another or to uncouple two component parts arranged movably with respect to one another, wherein at least one of the two locking bodies has at least one curved surface. In order to increase the wear resistance of the locking device, provision is made for at least one of the two locking bodies to have a plurality of curved surfaces of which the respective curvature is described by radii of identical length having constructional center points spaced apart from one another.
