Applying Euler's theory to the flow in annular circuit and taking the shock-and friction loss into consideration, the relation between the circulating velocity and the input-and output torque of general type hydraulic drive has been deduced. In order to carry out the numerical calculation and to discuss the characteristics of the hydraulic torque converter of all types systematically, a procedure finding out the reasonable arrangement of members in the circuit and the suitable shape of each vane has been derived as follows. Assuming that the shape of each member or vane may be expressed by radii and blade angles at its entrance and exit, and that the flow at the entrance of each member may be shockless at the specific operating condition which is named "reference point, " the energy equation, the shockless flow conditions and the conditions of maximizing the efficiency at reference point are obtained. Accordingly, the characteristics may be calculated numerically and systematically, by using the speed ratio and the circulating velocity at reference point as parameters. By way of example, the quantitative tendency of characteristics of single-stage torque converter for normal operation has been made clear.
