Abstract
An hydraulic machine which can operate either as a motor or a pump, the machine having a rotor and a stator, one of which is provided with lobed cam track means (16, 17, 18, 107, 108, 109, 400, 500, 604, 605) on which operate a plurality of phased series of piston and cylinder modules (105, 205, 306, 610) to impart relative motion between the rotor and stator. Modular valve means (13, 35, 102, 300, 606) control the supply of hydraulic fluid to each series of pistons.
