The invention relates to a liquid or pasty product dispenser comprising a mounted working piston (20). According to the invention, the dispenser comprises a hollow body (14) with a piston (20) mounted therein and a toothed wheel (24) is connected to the piston by means of threads, said piston being blocked in rotation in the body. In this way, when the toothed wheel is actuated, the piston moves axially and the product is dispensed in a controlled manner. Preferably, an outlet-sealing needle valve passes through the piston.
