Abstract

A multi-speed gerotor motor of the type including a fluid displacement mechanism (21) defining expanding (33E) and contracting (33C) fluid volume chambers, a stationary valve member (19), defining a plurality N of stationary valve passages, and a movable valve member (43). The upstream end of each valve passage communicates with the movable valve member (43), and the downstream end of each valve passage communicates with one of the volume chambers. In a plurality M of the stationary valve passages (79A through 79E) the upstream (81) and downstream (83) passage portions are blocked from direct communication, and for each there is a control valve member (103) which can, selectively, permit fluid communication for normal, low-speed, high-torque operation, or can block such communication, and recirculate the associated volume chambers for highspeed, low torque operation.
