<p>1. A distributing valve having a body (2) comprising : a distributing chamber (10) ; an inlet port (12) connected to the distributing chamber (10) ; a deflecting chamber (18) in communication with the distributing chamber (10) ; and an outlet port (14) which is also connected to the distributing chamber (10) and which is disposed at right-angles to the inlet port (12) ; and an axially movable valve spindle (6) which is disposed coaxially of the outlet port (14), extends out of the deflecting chamber (18) through a gland 32 and carries a distributing member (7) inside the distributing chamber (10), characterised in that the distributing chamber (10) and the deflecting chamber (18) are in shape spherical ; the body (2) has as connection between the distributing chamber (10) and the deflecting chamber (18) a cylindrical through port (16) ; a bush (18) subdividing th distributing chamber (10) into a cylindrical chamber (11) and an annular chamber (13) is mounted in the outlet port (14) and the through port (16), is formed with through orifices (25, 25') starting from the annular chamber (13) and bears the distributing member (7) radially ; and the distributing member (7), which is in the form of a body of rotation, has a narrow cylindrical circumferential surface (36) which is operative as bearing surface and into which concave quartertoroidal surfaces (37, 38) of rotation merge on both sides, the latter surfaces merging into the valve spindle (6).</p> |
