Abstract: The invention relates to a variable valve drive for a cam-actuated lift valve of an internal combustion engine which is loaded by a closing pressure against the direction of opening, with a hydraulic power generating device acting on the lift valve against the closing force with a control piston arranged longitudinally displaceable in a cylinder and adjacent to a hydraulic control chamber, with a stroke of the lift valve produced by an actuating cam being at least reducible by removing hydraulic liquid from the control chamber by means of a control valve. In order to arrange the valve stroke and valve opening as free as possible in the simplest possible way it is provided that the control chamber is connectable with a high pressure level preferably by means of the control valve.

Abstract: The invention relates to a connection (18) between a shaft end (14) of a gas exchange valve (1) of an internal combustion engine and a final control element (2) of a valve actuator (4), with at least two shell-shaped wedge-shaped pieces (22, 24), surrounding the shaft end (14) and braced on the final control element (2), whose radially outer circumferential surface extends conically and which are surrounded by at least one conical clamping sleeve (26) whose radially inner circumferential surface extends complimentary to the cone angle of the wedge-shaped pieces (22, 24), wherein on the radially inner circumferential surface (38) of the wedge-shaped pieces (22, 24) and on the radially outer circumferential surface (40) of the shaft end (14) of the gas exchange valve (1), protrusions (42) and recesses (44) that mesh with one another are provided. The invention provides that to enable rotary motions of the shaft end (14) relative to the wedge-shaped pieces (22, 24), the latter adjoin one another without gaps in the circumferential direction, forming an encompassing wedge-shaped sleeve (22, 24), whose inside diameter is slightly larger than the outside diameter of the shaft end (14) of the gas exchange valve (1), and that the protrusions (42) and recesses (44) mesh with one another with slight play.

Abstract: A switchable tappet for directly transmitting a cam lift onto a tappet push rod, includes a housing having a push rod distal end which is formed with a ramp surface for contact by a cam. An inner element is placed in a recess of the housing and has a push rod proximal end formed with an abutment for the push rod. Secured to the push rod proximal end of the inner element is an attachment to extend the inner element beyond the recess of the housing, wherein the attachment has a housing-distal end formed with a shoulder. A helical compression spring extends between the shoulder of the attachment and a rim of the housing for urging the inner element in a direction of the push rod, and conically expands, at least partly, in the direction of the push rod and is wrapped around the attachment of complementary conical configuration.

Abstract: In a valve train (1) of an internal combustion engine (10), a tappet push rod (2) comprises on its first end (3), a tappet (5) and an uncoupling device (8) made as a single component, and on its second end (4), a hydraulic lash adjuster (15) that acts on a rocker arm. Due to this spatial separation of the lash adjuster (15) from the single component (5, 8), a component (5, 8) is obtained that has a reduced mass and a smaller diameter as well as a relatively simple structure. In addition, the lash adjuster (15) can now be supplied with hydraulic medium directly out of the rocker arm.

Abstract: An engageable cam follower (1) for acting on a pushrod in the valve train of an internal combustion engine is provided. This cam follower (1) includes of a thin-walled hollow cylindrical housing (2) in whose borehole (3) is positioned an internal element (4) axially movable with respect to the housing (2). The housing (2) and the internal element (4) each possess a radial borehole (13, 10) aligned in a relative position to each other. Positioned in the radial borehole (10) of the internal element (4) is a piston (11) having a convex end (14) and movable toward the radial borehole (13) of the housing (2) for coupling the internal element (4) with the housing (2) in the relative position. According to the invention, the borehole (3) ofthe housing (2) is shaped in the area ofthe radial borehole (13) of the housing (2) as a flattening (15) extending in the longitudinal direction of the cam follower (1). This has the advantage that with the piston (11) positioned only slightly in the radial borehole (13) and with initial cam lifting, this piston (11) is load-bearing over a considerable portion of its periphery. As a result, removal of material from the piston (11), such as can occur in the state of the art and which can lead to jamming of the internal element (4) in the housing (2), is no longer encountered.

Abstract: In a tappet (1) comprising a hydraulic clearance compensation element (7), a positive opening of its one-way valve (15) is effected during a base circle region null of the contacting cam (5). This is achieved by the invention by the fact that a closing member (16) of the one-way valve (15) is loaded by an adjusting element (21). This adjusting element (21) extends through a bottom (3) of the tappet (1) and cooperates with a groove (22) on the outer peripheral surface (23) of the cam (5). This groove (22) extends over the entire periphery of the cam (5) with the exception of its base circle region. When the base circle region null comes to be situated opposite the bottom (3), a positive opening of the closing member (16) is effected. In this way, no undesired relieving of the gas exchange valve actuated by the tappet (1) nor its opening due to a transmission of undesired opening movements from the cam (5) to the clearance compensation element (7) can occur in the base circle region null of the cam (5).

Abstract: A valve system for an engine including a valve resting mechanism provided between an engine valve and a valve lifter supported by a cylinder head. The valve resting mechanism can place the engine valve into a resting state. The valve resting mechanism has a pin holder which includes a sliding hole having an axis perpendicular to the axis of a valve lifter, and an insertion hole for allowing a valve stem to pass therethrough. The pin holder is slidably fitted in the valve lifter. A slide pin is slidably fitted in the sliding hole, with a hydraulic force and a spring force applied to both ends of the slide pin. A containing hole is coaxially connectable to the insertion hole, and a rotation stopping means for stopping axial rotation of the slide pin is provided between the pin holder and the slide pin.
