Nozzle and a device for the use of a nozzle of this type
First Claim
1. A nozzle for regulating fluid flow in a fluid passage comprising, a flat part through which at least two cuts are made, each cut comprises a first groove on a first side of the flat part, a slit, and a second groove on a second side of the flat part, the cuts defining at least one tongue which is designed to be placed in the path of the fluid flow and is capable of being deflected, wherein the cross-section of the fluid passage is increased when there is a pressure differential between both sides of said tongue, said nozzle having a working range in which a delivery rate curve of the fluid is a linear function of the differential pressure in at least one part of said nozzle working range.

Abstract
A nozzle and a device for the application of the nozzle are disclosed. In the nozzle a mechanism is provided so that the dimensions of the hole for the flow of fluid can be varied according to the pressure differential between the inlet and the outlet. The above can be applied to the making of nozzles and/or devices, the delivery rate of which is directly proportionate to the differential pressure between the inlet and the outlet.
