Disc Valve Hydraulic Motors



In the late 1950's the low speed, high torque hydraulic motor was developed from a pump Geroter element consisting of an internal gear ring and a mating gear or star. While attaching the internal gear ring to the housing as a non moving part, oil was ported to pressurize and turn the internal star in an orbit around a center point. This slow turning star coupled with a splined drive to the output shaft became the Orbit motor.


A few years after this orbit motor was introduced another motor concept went into production. This motor had rolls incorporated into the internal gear ring, this element was identified by the name Geroler. From these early years the Geroler motor has seen many design changes to make these Geroler motors the best the industry has to offer.
