Class Information
Number: 137/803
Name: Fluid handling > Flow affected by fluid contact, energy field or coanda effect (e.g., pure fluid device or system)
Description: Subject matter wherein movement of a stream of fluid is controlled by one or more devices, at least one of the devices having the following characteristics:(A) the stream is caused to flow into the device through a passage or along a path of flow, or the stream is caused to flow in a predetermined condition or amount of flow into the device; (B) the stream is caused to flow out of the device through a passage or along a path of flow, and the stream is diverted to flow out of the device through a different passage or along a different path of flow, or the stream is caused to flow in an altered condition or amount of flow out of the device; (C) the diversion of alteration (referred to in (B) above) is caused by one or more of the following,(1) direct contact of at least one other stream of fluid with the inflow stream, or (2) application of an energy field directly to the inflow stream, or (3) application of the Coanda effect.
