Abstract
A short account of the origins of the hydraulic coupling is followed by a description of a production model and its method of operation. Tests have been carried out both on a transparent plastic model and on the full-scale production coupling. From the author's experience of the design and application of hydraulic couplings a mathematical analysis is made which uses conventional design formulae and general roto-dynamic theory. Dimensionless parameters and empirical laws are established which are useful in the prediction of design performance, and an examination of fluid friction and shock losses is made. Sample calculations on production couplings using the derived theory show close agreement with actual practice. A short description of a proposed test rig and future lines of experiment is appended.
