At least one cylinder head closes the cylinder, each of whose intake and exhaust channels are controlled by at least one intake valve and one exhaust valve (13, 13a). The intake and exhaust valves (13, 13a) are actuable by a rocker arm (5) or a finger lever driven by a camshaft (1) through intake and exhaust cams (2).

A brake control device is provided which includes, in the region of the base circle of the exhaust cam (2), at least one additional cam (1) for an additional opening of at least one of the exhaust valves (13, 13a).

摘要： A method for assembling a control valve in a hydraulic valve-lash compensation element, which is constructed for the control drive of an internal combustion engine as a reverse spring element is provided. According to the method, the compensation element is preassembled with a control valve spring (10), a ball (19), and a valve cap (20) of the control valve (11), so that the ball lift (21) caused by the construction of the control valve (11) is greater than a desired value required for the function of the element, after which the actual state of the ball lift (21) is measured and then the ball lift (21) is adjusted by deformation of the valve cap base acting as a contact surface (23) for the ball (19), in order to obtain the desired value of the ball lift (21) of the compensation element. In this way, for all of the compensation elements of the motor, the setting of the no-load lift to a constant value having only very small tolerances can be achieved.

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).

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).
