Abstract
The present invention provides a simple fluid atomizer having a pair of spring loaded sealing elements such that the pressure required to open both seals is the sum of the spring constants of each of the sealing elements. A central cavity is sealed at both its entry and exit by moving elements held by coil springs. When the fluid in the entry channel is able to overcome a first spring, the first sealing element is moved so as to allow fluid to enter the central cavity. When the fluid pressure within the central cavity reaches a level necessary to compress the exit spring, the entry fluid pressure must be at a level for achieving the delta pressure across both entry and exit springs.
