A self-adjusting orifice for fluids nozzle includes a membrane constructed of a single piece of flexible or elastic material. This flexible material is shaped to fit into the outlet of a nozzle. The body of the membrane has at least two flow channels, from one face to the other, which directs two streams of water to cross at the opening of the nozzle or at some point beyond. The elasticity and thickness of the membrane is selected to match the range of expected pressures and fluid velocities. The orifice may have more than two flow channels, as long as they are aligned adjacent to one another and directed towards each other at the exit face. In a three orifice embodiment, one is directed upward, one is directed downward, and the one in the middle is directed forward. In this embodiment all three fluid streams intersect at some point past the nozzle opening. Under increased pressure the membrane will deform causing the orifices to realign in a more forward direction, causing the streams to intersect at a smaller angle. This reduces the force with which the separate streams impact each other, still allowing the separate streams to unify into a single stable spiralling stream in spite of the increased pressure.

A self-adjusting orifice for a fluids nozzle, comprising: a flexible membrane placed in the path of fluid flow for said nozzle; said membrane having a plurality of flow channels in the direction of fluid flow, said flow channels passing through said membrane with entrance apertures and exit aperture

A self-adjusting orifice for a fluids nozzle, comprising: a flexible membrane placed in the path of fluid flow for said nozzle; said membrane having a plurality of flow channels in the direction of fluid flow, said flow channels passing through said membrane with entrance apertures and exit apertures, the channels being angled to cause intersection of the individual fluid streams exiting said apertures into a single stable spiralling stream; whereby an increase in fluid velocity causes said flexible membrane to deform and reduce the angle of incidence of the intersecting fluid streams, allowing the streams to continue to unify into a single stable spiralling stream.
