The discharge device according to the improvements includes two refractory pieces A and B, the first having a hole 1 forming the outlet nozzle, whilst the part B is movable and has holes 3 capable of facing the hole 1 in order to effect discharge of the fluid in question, it being possible to adjust the outlet diameter by rotationally sliding this movable piece B. Said piece B is mounted on a movable carriage 13 associated with rings carrying elastic elements and thrust elements 10, 17 and 18, and all the aforesaid being arranged between two plates 5 and 6, the latter as outer casing and the plate 5 as element for mounting on the base 8 of the distributor receptacle. The device as a whole constitutes what is known as a doubly elastic diameter interchange valve, causing, in one manner or another, the holes 3 in the movable plate B to lie opposite the hole 1 in the outlet nozzle A in order to effect the pouring and control and outlet of fluid at high temperatures in distributor receptacles. <IMAGE>
