A pulsating device with two preset pressure-responding normally-closed valves is disclosed. The first valve is used for accumulating fluid. The second valve is used for creating resistance so as to force the first valve to open widely. The second valve may be configured so it creates little to no resistance once opened. In some embodiments, the pulsating device converts a low controlled and/or continuous flow of fluid, such as water and/or air, to a high pulsating and/or intermittent flow. A pulsating device may operate, for example, one or more drip lines, pop ups, sprinklers, misters and/or other irrigation devices.

HOLDER AND SPRAY HEAD FOR PULSATING IRRIGATION DEVICE
A holder and a spray head for irrigation devices, including pulsating irrigation devices. The holder may be designed to accommodate a variety of ways of attaching the holder to a pole, stake, or other support. The holder may be designed to firmly hold and protect from damage an irrigation device or pulsating irrigation device. The spray head may include a cap and base removably coupleable together. The base may include a portion shaped or configured to mate with an irrigation device or pulsating irrigation device. When coupled together the cap and base form one or more channels through which liquid exiting the pulsating irrigation device travel before exiting the spray head. The one or more channels help direct the flow of liquid from the spray head in the desired direction or directions.
Apparatus for operating a group of normally closed, pressure compensated drippers at relatively low liquid flow rates includes a pulsating device having an inlet and an outlet that converts a low continuous liquid flow rate entering its inlet, through a flow control unit, to a high intermittent and pulsating flow rate ejected through its outlet. A manifold has an inlet connected to the outlet of the pulsating device, a group of normally-closed, pressure-compensated drippers being connected to the manifold. The pulsating device converts a low continuous flow rate of liquid entering its inlet, through the flow control unit, to a high intermittent and pulsating flow rate that ejects from its outlet and flows from its outlet through the manifold inlet and through the normally-closed, pressure-compensated group of drippers connected to the manifold, out from the drippers, at a pressure-compensated low flow rate.
