The exit part (15) is vented at a cross-section less than the first cross-section of the body member. The verting (31) compris es a branch(132), which is directed forwardly and downward ly of the nozzle, and a gate valve 40 capable of adjustably varying the effective orifice of the venting. The venting is arranged substantially parallel to a cut-off (30) of an end portion of the nozzle.
