The baffle provided with the central opening is interposed between the housing and outlet branch pipe from one side. The stabilizer with conical and bearing surface, central opening, and passages for flowing fluid is interposed between the inlet branch pipe and housing from the other side. The ribs of the stabilizer and the baffle are made at an angle to the flow of fluid. The valving member is provided with surfaces corresponding to the conical and bearing surfaces of the stabilizer and is mounted in the central openings of the baffle and stabilizer to cut off the passages for flowing fluid in the stabilizer. ^ EFFECT: enhanced reliability, reduced hydraulic resistance, and prolonged service life. ^ 1 cl, 6 dwg |
