Claim Text:
1. A gas or liquid conducting valve with a manifold, comprising: a manifold body defining a curved passage having a manifold inlet and at least one manifold outlet, the passage changing direction over the length of the passage between the manifold inlet and the manifold outlet, the curved passage having a center of curvature and a radially inward side towards the center of curvature; the manifold body having a plurality of sequential sectors in a region where the passage changes direction, the passage having a cross-sectional contour in each of the sectors; the cross-sectional contour of the passage merging from almost round or oval near the manifold inlet, through a plurality of cross-sectional contours in the plurality of sequential sectors that are flattened on the radially inward side of the curved passage, to an almost round or oval cross-sectional contour near the manifold outlet; wherein in a region of the flattened cross-sectional contours, each cross sectional contour has a plurality of arcuate sections that are continuous with one another and with the flattened section; and a gas or liquid conducting valve in fluid communication with the curved passage.
