ABSTRACT:
A torque generator steering device (11) including a gerotor gear set (17) disposed adjacent an end cap (15) and having the input shaft (21) extending through the end cap and through the orbiting and rotating star member (31). The valving of the device, including a spool valve (37) and a sleeve valve (39), is disposed on the side of the gerotor gear set (17) toward an output shaft (23). Preferably, the input shaft (21) is integral with the spool valve (37), and the sleeve valve (39) is integral with the output shaft (23). A coupling arrangement (77) is provided to translate orbital and rotational movement of the star (31) into rotational follow-up movement of the sleeve valve (39). The result is a very short, compact torque generator having substantially reduced backlash between the input shaft (21) and the output shaft (23).
