<p>The rotor distributor of the invention for viscous materials, especially concrete, has a stationary distributor plate (12) to which several supply lines (20) are flanged by their connectors (30) on the pump side. In addition there is an S-shaped distributor pipe (18) linked on the pump side to a feed stub (24) leading to the pump via a rotary coupling (22) and by its second connector (26) to a stub arranged on the rotary plate (16) and leading trough the latter to the distributor plate (12). The rotary plate may be turned about the axis of the feed stub (14) in relation to the distributor plate (12), while the connector stub (28) may thus be connected as desired to the various supply line connectors (30). On the rotary plate (16), stop cams (32) are arranged at the angular distance between the supply line connectors (30) and can be rotated in the forward direction (38) of the rotary plate (16) past a pawl (36) located beneath the distributor plate (12) and, in the rearward direction, come against it with the connector stub (28) aligned with the appropriate supply line connector (30).</p> |
