<p>A b s t r a c t The distribution valve comprises an inlet spigot (12) and a first outlet spigot (14). The two spigots (12 and 14) are connected to a distribution chamber (10) and are disposed at right angles to one another. Diametrically opposite the outlet spigot (14) a passage spigot (16) leads to a deflection chamber (18). An axially displaceable valve spindle (6) leading out of the deflection chamber (18) via a stuffing box (32) is disposed coaxially of the outlet spigot (14) and the passage spigot (16) and bears a distribution member (7) in the region of the distribution chamber (10). A second outlet spigot (22) is connected to the deflection chamber (18). Distribution chamber (10) is divided into a circular cylindrical chamber (11) and an annular chamber (13) by a bush (8) mounted in the passage spigot (16) and in the outlet spigot (14). Bush (8) has passage apertures (25) leading from the annular chamber (13) and supports the distribution member (7) radially. The bush provides a good guidance of the distribution member so that the latter and the relatively long valve spindle cannot be set into vibration. (Fig. 1).</p> |
