Abstract (en)
[origin: DE19903278A1] The invention aims at reducing the weight of a box piston having a running surface, the width of which in the pressure side is different from the width of the running surface on the counterpressure side. To this end, the piston has at least one bent channel that is cast using bent sleeves and is located at least partly above the bolt hubs with a tapering cross section extending approximately in the direction of pressure-counterpressure.
