Abstract
The torque converter includes an elongate housing having a main section and a collar section. A piston assembly is reciprocable inside the main section. A plurality of elongate helical bolts with outer helix extends axially from one side of a piston. The opposite side of the piston is entirely exposed to hydraulic forces to maximize potential work thereon. The helical bolts are mated with a rotator in a helical rotation assembly, converting linear motion into rotation, each mated pair generating a given torque. A torque accumulator combines the given torque to generate total output torque greater than the given torque. One or more output endcaps can be provided on the ends of the housing to produce work from the greater output torque.
