Abstract

The barrel (11) drilled with through-ports (A to G) is housed inside a rotating actuation ring (5) of larger diameter with which it meshes. This arrangement allows both a compact arrangement and a closed construction avoiding any loss of flowing material in the event of untimely actuation of the barrel. <IMAGE>
