Abstract:

The author describes the construction and operation of fluid control devices and discusses parameters which are important for practical application. The discussion and description are limited to pneumatic quasibidimensional elements which operate chiefly on a laminar air jet. The basic characteristics of light fluids which are useful in construction of these elements are given as well as the various types of possible control devices. The use of the Coanda effect in making bistable devices such as flip-flops is discussed. It is shown that logic elements may be constructed by taking advantage of this effect and that analog elements may be made by widening the inlet chamber and reducing the distance between the power stream nozzle and splitter to eliminate the Coanda effect. This device gives an output proportional to the control stream. Some of the possibilities for application of fluid control devices in industrial automation and computer technology are considered.
