  • the displaceably guided shift pin 26 has a plurality of grooves positioned in the direction of displacement S one behind the other.
  • the shift pin 26 comprises two grooves 38 and 39, which are each designed as annular grooves.
  • the shift pin 26 cooperates with the stop 27, according to Fig. 5 is provided by a blocking element 40, which is acted upon by a spring element 41.
  • Fig. 5 shows the shift pin 26 fragmentary in a fully retracted position in which the shift pin 26 the part-load swing lever 14 and the full load swing lever 13 from each other, in which case a front end 42 of the shift pin 26 seen in the extension of the shift pin 26 behind the locking element 40 and thus the Stop 27 is retracted.

  • Fig. 6 also shows the shift pin 26 in sections in a fully retracted position. Fig. 6 can be seen that such portions of the shift pin 26, which cooperate with the stop 27 and acted upon by the spring element 41 locking elements 40 in the fully retracted position of the shift pin 26 against a provided in the embodiment shown by the partial load rocker 14 bearing housing 43 for the shift pin 26 protrude.

Only then, when the shift pin 26 is extended so far that the projection 44 is completely moved out of the hydraulic line 25, is in this case the full hydraulic effective surface of the shift pin 26 ready. In this respect, the full hydraulic power for hydraulic actuation of the shift pin 26 in the variant of Fig. 7 only available when the shift pin 26 is extended a defined distance. Thus, a pressure and speed controlled extension of the shift pin 26 can be realized.
  • an additional discharge opening for hydraulic oil may be present in the region of the housing 43 of the switching pin 26.
  • This additional, not shown in the figures discharge opening for the hydraulic oil allows faster retraction of the shift pin 26 in the separation of full load rocker arm 13 and part load rocker arm 14 and so a mechanical relief of the shift pin 26, such additional discharge opening is preferably hydraulically piloted.
  • this additional discharge opening When extending the shift pin 26, this additional discharge opening is closed, only when retracting the shift pin 26, the additional discharge opening is opened. This can be realized via a spring-loaded ball valve, which closes the additional discharge opening for extending the switching pin 26 and releases the same for retracting the switching pin 26.
