The invention discloses a valve housing () having a main bore () and at least one connecting bore or secondary bore (), the diameter of which is smaller than the diameter of the main bore. The connecting or secondary bores end at a side wall limiting the main bore, wherein the side wall has different material thicknesses being distributed at the circumference thereof. According to the invention, to reduce material stresses the valve housing has tension reducing grooves () in the ending regions, said grooves being integrally molded into the side wall of the main bore.
