Abstract: A sealing system is intended for wet cylinder liners and having a flange seat on the crankcase of internal combustion engines. Sealing rings are respectively provided in the recess and in an annular groove arranged in the area of the upper guiding portion of the liner. The annular groove should not reduce the length of the guiding portion by more than 40%. In this manner, salt crystals forming as cooling water evaporates are prevented from penetrating up to the top sealing ring, so that this ring will not be corroded, and its sealing action is maintained.

Abstract: A control device for turbines with speed and load control, in which the load control includes an integrator with or without an output value limiter. The speed control and the load control are functionally independent of each other over the entire working range. The speed control likewise includes an integrator, and the outputs of the two controls are conveyed to a MIN-member as input signals while the smaller input becomes the output signal of the MIN-member and takes over the positioning of the turbine inlet valve.
