ABSTRACT:
A valve for water sprinklers and the like, with an inlet and first and second outlets, has a hinged clapper biased to close the second outlet but held closing the first outlet by a dosing device after delivery of a given volume of liquid through the first outlet. The dosing device includes a chamber communicating with the inlet via a flow regulator. Filling of the chamber with liquid moves a piston extended by a rod cooperating with the clapper.
