US Patent:

20140042250, Feb 13, 2014

Filed:

Aug 9, 2012

Appl. No.:

13/571227

Inventors:

Peter A. Maksymec - Las Vegas NV, US
Joseph Ostrowski - Henderson NV, US

International Classification:

B05B 1/30

US Classification:

239569

Abstract:

A flow control device sized to fit into a pop-up sprinkler inlet reducing the cross-sectional area of the inlet thereby controlling the volume of water by restricting the flow able to pass through and inducing a pressure drop to the sprinkler head for correct droplet formation. A tapered body with spaced ridges permits the flow control device to “snap into” pop-up sprinkler inlets of different sizes. A top surface of the flow control device includes a small opening which acts as the new inlet. A cover cap and stem spring assembly of the pop-up sprinkler are removed from an installed pop-up sprinkler body revealing the inlet allowing the flow control device to be pressed downward into the inlet until one of the ridges snaps in place. The cover cap and stem spring assembly are then returned to the body completing the retrofit. A universal flow control device is also disclosed.

International Classification:

B05B 1/30

US Classification:

239569

Abstract:

A sprinkler riser having an integral water flow restrictor. The water flow restrictor is built into the riser rather than comprising a separate apparatus configured for insertion into the riser. A two component water flow restrictor allows orifice size to be adjusted to control and adjust the quantity of water permitted to pass through the riser.

International Classification:

B05B 1/30

US Classification:

239583

Abstract:

A flow control device which securely fits into a gap between an irrigation riser and orifice in a sprinkler head. One version includes a threaded outer edge which mates with threads on an inner surface of the irrigation riser. Another version incorporates pliable outer edges to fill in threads on an inner surface of the irrigation riser.
