    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: A hydraulic valve play compensation element for an internal combustion engine is provided as a reverse-spring/free-ball element, with a cylindrical housing, a cylindrical piston (21) guided therein with sealing play and a control valve (20), which is arranged between a low-pressure chamber (22) of the piston (21) and a high-pressure chamber (24) of the housing, on a piston head (25) of the piston and which has a closing body (27), which can contact a valve seat (26) surrounding an axial bore hole (23) of the piston head (25) when carrying out a stroke (28) in the closing direction against the force of a control-valve spring (34) and which can contact a contact surface (29) of a valve cap (30) surrounding the closing body (27) when carrying out a stroke in the opening direction. In a region of the axial bore hole (23) for the closing body (27) there is a narrow guidance surface (32) with gaps, which enable a volume flow of hydraulic medium between the high-pressure chamber (24) and the low-pressure chamber (22).

    摘要: The invention proposes a coupling mechanism (1) for relatively movable elements (2, 3) of a switchable cam follower (4) of a valve train of an internal combustion engine, a high lift being obtainable upon coupling of said elements (2, 3) and a lift smaller than the high lift being obtainable upon uncoupling of said elements (2, 3), a first one (2) of said elements comprising a guide bore (5) for at least one coupling piston (6) which, for achieving coupling, can be displaced partly beyond a parting surface (7) between said elements (2, 3) into an aligned reception (8) of a second one (3) of said elements, wherein upon cam lift and coupling of said elements (2, 3), a contact zone (9) between the piston (6) and the reception (8) is clearly spaced from an edge section (10) of the reception (8) on the parting surface (7). This can be implemented in practice, for instance, through a special “backwards” oriented flattened portion (14) on the piston (6). Material loading on the edge section (10) is thus avoided.

    摘要: What is proposed is a hydraulic lash adjuster (1), for example for a valve train of an internal combustion engine. The lash adjuster (1) comprises a hollow cylindrical housing (2) that is inter-inserted with an axially relatively displaceable pressure piston (3). A high pressure chamber (6) for hydraulic medium extends between opposing front ends (4, 5) of the pressure piston (3) and the housing (2). The high pressure chamber (6) can be supplied, via a one-way valve (8) arranged on the front end (4) and opening towards the high pressure chamber (6) with hydraulic medium out of a reservoir (9). A leak gap (12) for the hydraulic medium is formed between an outer peripheral surface (10) of the pressure piston (3) and a bore (11) of the housing (2). In its portion adjoining the front end (5) of the housing (2), the bore (11) of the housing (2) merges into an annular enlargement (15). According to the invention, the front end (4) of the pressure piston (3) comprises in its transition region to the outer peripheral surface (10), a chamfer (16) whose height (HF) is equal to or larger than a height (HR) of the annular enlargement (15). In this way, it is effectively prevented that undesired particles situated in the high pressure chamber (6) get deposited on the outer peripheral surface (10) of the pressure piston (3) in the sunk state thereof, and penetrate into the leak gap (12) during the subsequent adjusting operation with the danger of a clamping of the pressure piston (3).
