Definitions

  • the invention relates to a valve control for a reciprocating piston internal combustion engine according to the preamble of claim 1. With this arrangement, actuation of the valves free of shear force is to be achieved.
  • Figure 1 cross section of a cylinder head in the region of a pair of valves.
  • FIG. 2 partial section along the line II-II in Fig. 1. ⁇
  • valve control for two valves 12, 13 is arranged, which are actuated together by a rocker arm 14.
  • rocker arm 14 is moved by a bumper 15.
  • the movement of the rocker arm 16 on the valve side is transmitted by a pressure piece 17 to a crossmember 18, which in turn interacts with the shaft ends of the valves 12, 13 via pressure pieces 19, 20.
  • the cross member 18 is guided parallel to the valve axes on a cylindrical bolt 21 fastened in the cylinder head 11.
  • the device for securing against rotation consists in the formation of a groove 22 at one end the traverse 18 outside the valve axes, which slidably engages over a guide part 23 arranged on the rocker arm 14.
  • the guide part 23 arranged in the area of the rocker arm hub which in the example consists of a molded rib, extends so far parallel to the valve axes in the direction of movement of the cross member 18 that an overlap between the groove 22 and the guide part 23 is ensured in all operating positions of the cross member 18.
  • the device for securing against rotation is at a greater distance from the guide axis of the crossmember 18 - the axis of the bolt 21 - than the pressure pieces 19, 20.
  • the possible swivel angle of the crossmember 18 resulting from the lateral play between the groove 22 and the guide part 23 results in the pressure pieces 19 , 20 a smaller lateral offset with respect to the valve axes than the dimension of the lateral play between groove 22 and guide part 23 corresponds.
  • the device for securing the cross member 18 against rotation can advantageously also be arranged such that it is effective between the cross member 18 and an adjacent housing wall 24.
  • a guide part 23 ' can be arranged on the corresponding housing wall 24 and the associated groove 22' at the other end of the crossmember 18, see dash-dotted representation in Fig. 1st
