ABSTRACT:
A distributor, notably for use in a sprinkling or like system, for causing a liquid to flow successively through a first orifice, then through a second orifice, but only after a predetermined quantity of liquid has passed through the first orifice. This distributor comprises a volumetric metering device comprising a piston movable in a first direction under the influence of the liquid pressure from the inlet orifice to a first orifice via an open valve, a chamber and a passage. A piston comprises a rod provided with a push member capable of moving a control member in the first direction, this control member being then driven for rotation by a driving member coupled kinematically to a turbine. Simultaneously, the driving body closes the valve and after a predetermined rotation of the control member the cavity thereof registers with the push member and the rod can move freely in the first direction and close the first outlet orifice while opening the second outlet orifice.
