A rotary valve (6) is equipped with control profiles (12) comprising profiled heads (12.1) and profiled ends (12.2) between which control slots (13) are formed. The profiled heads are arranged on the rotary ring, and the profiled ends are arranged on the fixed ring. Width of each control slot is equal to width of each control profile. Blades (14) are arranged between the profiled ends in the fixed ring, which divides each control slot of the fixed ring into two partial slots (13.1, 13.2).
