The pressure chamber is arranged in scroll-like form and is profiled-convex. The planes of the openings of the inlet and the outlet branch pipes are placed either in one horizontal plane, and axes of those are parallel, or in parallel vertical planes with centers of openings of the branch pipes at one axis. |
