Underground sprinkler with pop-up head object of the invention |
摘要 |
An underground sprinkler with a pop-up head and a corresponding underground casing has two differentiated cylindrical parts, closed by a corresponding cover fixed to the pop-up sprinkler head, which, being a part coupled to the piston, pops-up due to the effect of the water pressure pushing the piston in a portion calculated for this purpose and which is so maintained for as long as the pressure lasts, to be recovered by the action of a permanent draw-spring when the pressure stops.
