Definitions

  • the drive cams 11a to 11d are designed such that a longer rest of the pump piston 14a to 14d takes place both in the lower and in the upper dead center position, which ensures that one of the control slides 24 is not influenced when one is actuated, because Both in the lower and in the top dead center position, the annular groove 43 on the pump pistons 14a to 14d closes the connection from the pressure chamber 28 via the control line 29 to the common control pressure line 31.
