Abstract: The dispensing device comprises a dispensing valve comprising: a valve body (40); an actuating rod (42), defining a dispensing duct for the product (62); a return element (44) of the actuating rod (42) to its blocking position. The dispensing device comprises a non-return valve (70) arranged inside the actuating rod (42). The non-return valve (70) comprises a deformable portion (74) between a closed position, applied against a lateral face (61) of the actuating rod (42), in which the circulation of fluid in the duct (62) through an inlet orifice (64) for product entry in the rod is made impossible, and an open position, separated from the lateral face (61) of the actuating rod (42), in which the circulation of fluid through the inlet orifice (64) is possible.
