摘要： A pipe for supplying pressure medium to valve train elements, including: an outer wall; a partition located inward of the outer wall and twisted in a spiral along the outer wall; a first gallery formed by the partition and the outer wall; a second gallery formed by the partition and the outer wall and separate from the first gallery; and a plurality of overflow openings. Each overflow opening opens to the first gallery or to the second gallery.

摘要： A switchable finger follower for a valve train of an internal combustion engine includes an outer and an inner lever, which at a first longitudinal end run pivotably relative to one another via respective bores on a common shaft. At this longitudinal end, the finger follower has a gas-exchange valve contact face on an underside. The outer lever has a pivot bearing on the underside at a further longitudinal end, and at least the inner lever has a cam running face on an upper side. The inner and outer levers are connectable to one another via at least one coupling slide, which spans a separation area between the levers. The outer and inner levers are braced relative to one another via a cam return spring, and the shaft is connected to the bore of the outer lever by an interference fit. To mount the inner lever relative to the shaft without radial play but in a rotatable fashion, the bore of the inner lever includes, in its semi-circular segment facing the upper side, a pointed arch composed of two circular arcs as contact means.

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.

摘要： The disclosure relates to a switching element comprising an external part and an internal part, which is axially displaceable in a bore of the external part. At least one radially displaceable locking element is disposed within at least one receptacle of the internal part and includes a flattened portion on a radially outwardly directed end. At least one recess of the external part can be acted upon by a control pressure and the at least one locking element can thereby be radially displaced from the locking position into a release position. At least in a respective locking position, a chamber delimited by the at least one locking element is spatially separated from the at least one recess of the external part by a respective locking section. At least one bypass is designed, which indirectly fluidly connects the at least one recess of the external part and a respective chamber.

摘要： A variable valve drive of an internal combustion engine is provided that includes at least one gas exchange valve, the valve stroke of said gas exchange valve predefined by cams of a camshaft, and by at least one switchable rocker arm. The switchable rocker arm, having a first lever and a second lever, selectively transmits cam lift to the gas exchange valve. The second lever is selectively coupled to the first lever by a coupling. The coupling is activatable by an elongated activation arm on which one leaf spring is disposed for the coupling of the switchable rocker arm. The elongated activation arm is longitudinally displaceable from a locking position to an unlocking position by a linear actuator. A damper mass is disposed or configured to be capable of oscillating on the elongated activation arm and/or on the leaf spring of the elongated activation arm.

摘要： A pre-assembled module for a variable-stroke valve drive of an internal combustion engine is provided. The module includes a base plate having at least one projecting guide plate, an e-linear actuator positioned on the projecting guide plate, and a longitudinally guided push rod with two adjusting fingers extending along a wall of the guide plate. Each respective adjusting finger has a contact surface for displacement of a transverse coupling slide of a switchable cam follower. A rocker arm, having first and second arms, is suspended on an underside of the base plate; the first arm in contact with an adjusting pin of the linear actuator; and, the second arm in contact with the push rod for displacement thereof in a first direction. A spring means for displacement of the push rod in a second direction is arranged between the push rod and the guide plate.

摘要： A preassembled module for a variable-lift valve drive of an internal combustion engine is provided for installation into a cylinder head. The module has a base plate with an electric linear actuator which lies on an upper side of the base plate. A guide plate, which lies on the upper side, has an outer side wall arranged to guide a slide piece. The guide piece extends below the base plate two downwardly pointing actuating fingers. Each respective actuating finger has a contact surface for moving a transverse coupling slide of a switchable rocker arm. The slide piece has a bracket which protrudes over the guide plate with a contact landing arm which runs transversely relative to the electric linear actuator. An actuator-side end of the contact landing arm is in contact with an actuating pin of the electric linear actuator to move the slide piece.
