摘要： A rocker or swing arm in a valve train of an internal combustion engine has a bearing bore pivotally supporting the arm on a hollow axis located in a fixed position in the engine. The valve train has a camshaft with cams for causing the arm to pivot. A hydraulic valve lash compensation element that acts on the tappet of a gas exchange valve connects to the arm. A supply line is arranged in the arm, and a radial opening connecting the hollow interior space of the axis to the supply line is arranged in the axis in the region of the arm to deliver hydraulic means through the hollow axis to the lash compensation element. According to the invention, a A labyrinth seal (35) surrounding the hollow axis without contact is arranged on the arm at each axial end of the bearing bore. The bearing space of the arm is laterally sealed by this means.

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).

摘要： A valve timing mechanism of an internal combustion engine of a motor vehicle, having a camshaft having at least one cam (18), via which a switchable valve timing mechanism element (1) can be loaded with a cam stroke (s), in which locking means (12) are arranged on the valve timing mechanism element (1), which locking means (12) have a locking play (16) which is active in the direction of a valve stroke, in which the cam (18) has a base circle region (α) and a ramp region (19) with an opening ramp (γ) which adjoins the base circle region (α), and in which at least one ramp section (21) is formed on the opening ramp (γ) in order to compensate for the locking play (16). In order to provide a valve timing mechanism of an internal combustion engine, which produces sufficient idle travel of a locking play (16) of the switchable valve timing elements (1) being loaded by the cam ramps of the cams (18), and nevertheless manages with a relatively short length of the cam ramps, the cam (18) is shaped in the locking play ramp section (21) for compensating for the locking play (16) in such a way that, during a run-off movement over a cam counterelement (17) of the valve timing mechanism element (1), in the event of a rotation of the camshaft, it runs off with an increased cam velocity (v) in comparison with adjacent ramp sections (20,24), at least in one part of the locking play ramp section (21).
