Definitions
- the invention relates to a valve train for an internal combustion engine, with a driven Cam element and with one of the cam area of the rotating Cam element against a closing spring openable valve, which is a hydraulic Backlash compensation device with a supply line provided with a check valve and a derivative for a pressure transmission medium, the derivative by means of a spring-loaded locking element over the cam area of the Cam element is closed and open over the base circle area.
- Mechanical valve trains with hydraulic lash adjusters are in large number and known in different versions. They serve the valve to adjust in the valve seat so that it over the base circle area of the cam element is actually closed properly.
- the adjustment results from the level of the pressure transmission medium, in particular oil, in the pressure chamber caused by Change in the inflow can be set.
- the derivative shows an increased Flow resistance, for example due to a small cross section, a throttle element or the like, in order to avoid rapid drainage. Because such Valve clearance compensation has the disadvantage that the medium from the pressure chamber too during the opening of the valve, i.e. during the application by the The cam area of the cam element exits via the derivative was described in DE 41 24 184 A proposed a valve train of the type mentioned, the tappet includes.
- a sliding inner sleeve is arranged in the cup, and in the space between the cup and the inner sleeve engages in the cylinder head an adjustable intermediate sleeve, with passage openings in the sleeves are opened or closed depending on the position of the cam element. On this is the exit of the pressure transmission medium during the valve opening prevented, and the game compensation element can not be compressed. The Through openings are only cleared again at the transition to the base circle area, so that the valve clearance is established.
- the invention has now set itself the task of switching the locking element to simplify, and suggests that the base circle area of the cam member is provided with a space into which the locking element or one assigned to it Holding part can occur.
- the free space opens from the transition from the cam area to the base circle area of the cam element and the locking element can under the action of a spring be moved so that the derivation of the pressure transmission element is released becomes.
- the locking element can be in the pressure chamber of the hydraulic accumulator compensation device be arranged, it being displaceable in the valve axis lie and with a second end directly in the free space of the cam element can intervene.
- the blocking element is preferably laterally next to the Match compensation device arranged on the holding part, wherein the holding part Compression spring is assigned, which holds the holding part in the recess of the cam element suppressed.
- the holding part of the locking element is preferably displaceable on the play compensation device arranged, and the pressure spring between the game compensation device and the holding part provided.
- the holding part the game compensation device protrudes axially on both sides and limit stops for the displacement the game compensation device.
- the force of the compression spring is preferably essential less than that of the valve closing spring.
- a valve train for an intake or exhaust valve 13 of an internal combustion engine has one driven camshaft on which at least one cam element 1 is arranged, that opens the valve 13 against a valve spring 14.
- the cam element 1 has one Cam area and a base circle area in which one with respect to the Base circle 3 deepened space 2 is provided.
- a hydraulic lash adjuster provided between the cam element 1 and the valve 13 a piston 10 acting on the tappet of the valve 13, a cup-like Actuating cylinder 18, in which the piston 10 slidably engages, and a pressure chamber 14 between the piston 10 and the bottom of the actuating cylinder 18 comprises.
- the pressure room 14 is via a feed line 17 and a check valve 16 with a Pressure transmission medium, in particular oil, can be filled and via a discharge line 6 can be emptied, in which a check valve 9 and a throttle element 7 in a row are arranged.
- a holding part 19 is slidably arranged on the actuating cylinder 18, which projects axially on both sides via the actuating cylinder 18 and into the displacement path of the Actuating cylinder 18 has protruding limit stops 5, 11.
- the holding part 19 is further provided with a bottom on which the cam element 1 rests. Between the actuating cylinder 18 and the holding part 19, a compression spring 4 is provided, which Holding part 19 presses against the cam element 1.
- a locking element 8 is connected to the holding part 19, so that when the holding part 19 is moved, the locking element 8 is also moved, and the check valve 9 opens or closes.
- the valve train now works as follows: At the beginning of the opening phase of the valve 13, the cam element 1 has the position shown in FIG. 1, in which the on the contour of the base circle 3 between the free space 2 and the cam area lying circumferential section rests on the holding part 19. If the cam element 1 rotates in the direction of the arrow in the position shown in Fig. 2, the holding part 19 pushed down. The actuating cylinder 18 lies on the stop 5 of the holding part and is also moved. The check valve 16 blocks the feed line 17, and that Blocking element 8 blocks the discharge line 6, so that the one enclosed in the pressure chamber 14 Pressure transmission medium can not escape. The loading by the Cam element 1 is thus transmitted directly to the piston 10, which is on the valve lifter is applied.
- valve 13 lifts off the valve seat 12 and opens the inlet or Outlet region. With the further rotation in the position of FIG. 3, the relative remain Positions of all parts to each other unchanged, so that the valve 13 through the Valve spring 15 is moved back into the valve seat 12.
- the derivative 6 remains locked, and the volume of the pressure chamber 14 unchanged. Since also the actuating cylinder 18 abuts the stop 5, the holding part 19 follows the receding contour of the Cam area until base circle 3 is reached.
- the compression spring 4 takes over the further displacement of the Holding part 19, and the blocking element 8 from the check valve 9 - at least schematically - pulled out so that the derivative 6 is opened.
- excess Pressure transmission medium can be braked by the throttle element 7 from the Drain pressure chamber 14.
- a lower stop 15 of the holding element 19 limits the Effect of the compression spring 4, i.e. the actuating cylinder 18 can only touch the system on Stop 11 are moved, causing an excessive reduction in Pressure chamber volume is prevented despite the open shut-off valve 9.
