Concrete vibrator with continuous mould release comprising a distribution slide valve for the mortar of approximately prismatic shape and more or less twice as wide at its base as it is deep, composed of a rear inclined plane (9) acting as a back wall, of a front wall (8) and of two lateral walls which are arranged so as to form a discharge orifice located at the front and coinciding, during the filling phase, with the shuttering, provided with four wheels (5, 6) mounted on two axles, one at the front and one at the rear, and motorised by means of two connecting rods fixed to two shafts provided for this purpose on the flanks (7) of a carriage, more or less in the middle. According to the invention, the width of the discharge orifice is greater than that filling width of the shuttering (formwork) of standard dimensions by at least 45 mm to the right and 45 mm to the left, such that the width of the lateral "mud flaps" (15) is reduced as far as possible, the lateral walls of the slide being almost vertical. <IMAGE>
