Distributing pump, which comprises, in combination: a cylinder, a piston movable in a cylinder, having a driving rod with an axial through hole, constituting a discharge channel from the inside of the cylinder, whose rod has between its two ends a projection inner annular forming a discharge valve seat, a discharge valve placed in an axial cavity, whose valve is fitted with the valve seat to close the discharge passage and has a stem projecting from the passage, a driving button placed at the end of the piston rod, a device for clamping the valve stem with the cylinder, which device thus effects the clamping of the discharge valve by means of actuating the button, the piston rod and the piston to move this in the cylinder effects a separation of the valve from the valve seat, said piston rod and the piston being molded in a single piece of elastic plastic; the discharge valve is slightly larger in diameter than the opening of the valve seat, being susceptible said valve seat expands in a circular manner within limits and is extended enough so that the valve can be forced through it so that the valve stem extends through the seat, and through and out of the piston towards the end of the cylinder beyond the piston.
