Abstract
SYNOPSIS A torque converter is described in which the prime mover is directly coupled to a pulsator unit which produces an alternating torque. Sprag-type clutches are used to rectify this torque and to transmit it to the converter output shaft.
A developed version of this basic design for use as an automobile automatic transmission is described and theoretical and experimental performance curves are given which show that an automobile drive is possible which approaches a manual transmission for fuel consumption and performance.
