摘要： The valve train assembly with magnet uses the magnet to collect ferrous metal particles that are in the oil prior to their arrival at the high pressure cavity of the hydraulic lash adjuster. The magnet can be positioned in the low pressure cavity of the hydraulic lash adjuster, in the bore of the hollow rocker arm shaft or in the bore of the hollow push rod.

摘要： A guide rail (1, 22) for valve tappets (2) of an internal combustion engine is provided. The guide rail (1, 22) has receptacle spaces (4), which are each used for receiving one of the valve tappets (2) and in which there are flattened sections (6) interacting in a positive-fit connection with key surfaces (7) of the valve tappets (2), such that each of the valve tappets (2) is protected from rotating about its longitudinal axis, with the flattened sections (6) permitting alignment of the valve tappet (2) parallel to the flattened sections (6). Here, the guide rail (1, 22) is formed as a metal carrier (3, 25) and rotational protection elements (8, 9, 23), which are fixed on this carrier, have the flattened sections (6) which also permit alignment of the valve tappet (2) orthogonal to the flattened sections (6), in that each flattened section (6) belonging to one of the receptacle spaces (4) can be displaced relative to the metal carrier (3, 25).

摘要： The invention concerns a mounting and anti-rotation device (mounting aid) (1) for roller tappets of a valve train of an internal combustion engine in which gas exchange valves are activated by roller tappets. The roller tappets comprising a substantially cylindrical tappet body are retained in receptions (7, 8) of the mounting aid (1) that is made of plastic. With the help of opposing parallel anti-rotation surfaces that are arranged symmetrically to the longitudinal axis of the roller tappet and are disposed on the end of the tappet body that is oriented away from a roller, the roller tappets are guided secured against rotation in the mounting aid during the operation of the internal combustion engine. This is achieved by the fact that the inner profile of the receptions (7, 8) is matched to the outer profile of the roller tappets. To avoid mixing up the switchable with the non-switchable roller tappets during assembly, the distances between the anti-rotation surfaces on the different roller tappets, and thus also the inner contours of the corresponding receptions (7, 8) are chosen so as to differ markedly from each other. To achieve the correct orientation of the switchable roller tappets, for example, relative to an oil gallery, the anti-rotation surfaces of the switchable roller tappets and the corresponding receptions (8) of the mounting aid (1) are arranged asymmetrically to the longitudinal axis of the tappet body and comprise a groove (32) or a rib (35), respectively.

摘要： Valve train with hydraulic lash adjustment in the entire timing train, in which oil is delivered from the oil supply space of the hydraulic valve-lash adjuster (HLA) to the valve rocker arm via a hollow push rod, a choke limiting the oil discharge, the choke being designed in such a way that it seals off the push rod bore at the top when the oil pressure drops, that is to say when the engine is shut off, so that the oil is retained in the push rod bore (12) until—after the engine is started—the choke body (15, 22) opens up the discharge opening again.

摘要： A switch element (1) is proposed for valve shut-off, fabricated as cam follower for a plunger rod valve drive of an internal combustion engine, having an outer part (2) and an inner element (4) axially movable in its bore (3) and with rotational security (15) relative to the guided inner element (4). The outer part (2), inside the bore (3), has an annular groove (6), and the inner element (4) has a radial bore (7) with two diametrically opposed pistons (8), which to couple the elements (2, 4) in their axially remote relative position achieved by a lost-motion spring (5) are displaceable towards the annular groove (6). On their cam-side under side, emanating from their radially outward, bulbous face, the pistons (8) segmentwise comprise a plane transverse surface as contact area for a facing under side (27) of the annular groove (6). The latter is intersected by two diametrically opposed oil ports (11) running offset 90° from the pistons (8) in circumferential direction. In addition, the outer part (2) has means (13) for rotationally secured guidance of the switch element (1) relative to a surrounding structure.

摘要： A switching element (1) for a valve drive of an internal combustion engine, preferably for shutting off valves, is provided, and includes an external part (2) in whose bore (3) an inner element (5) is axially movable. The external part (2) and the inner element (5) have at least a respective mutually aligned recess (7, 8) due to an axially spaced relative position obtained through a lost motion spring (6), and in one of the recesses, in the direction of the other recess, displaceable coupling means (9) are mutually applied in the relative position for coupling the inner element (5) with the external part (2). Two pistons (10) are provided as coupling means (9), which travel in the recess (8) formed as a radial bore of the inner element (5), and which diametrically oppose one another. The recess (7) of the external part (2) is formed as an annular groove (16) in the bore (3), and the pistons (10) at their underside (17) remote from the cam, starting from their radially external end faces (13), sectionally have a planar transverse surface (14) as contact region to a facing annular surface (15) of the annular groove (16), and the pistons (10) are guided with rotation securement (19) in the inner element (5). This provides a switching element (1) which has a simply constructed coupling mechanism, which produces only a small component loading.

摘要： A rocker arm for a tappet pushrod valve train, which has a contact surface for a gas exchange valve on an underside at one end and a first bore in which a hydraulic lash adjusting element is arranged at another end. A second bore extends transverse through the rocker arm, between the ends. From the second bore, a passage leads to the first bore. A venting passage extends from a bottom of the bore at the another end and has an outlet aligned with the primary passage. A secondary passage branches from the venting passage and has an opening that extends to an upper side of the rocker arm and is situated in a longitudinal channel. The channel extends along the upper side and into a region on the one end. From the region, the hydraulic medium can be routed through an end passage to the contact surface.
