Abstract

A hydraulic turbine motor has a rotor housing and a rotor rotatably supported in the rotor housing that defines a plurality of rotor chambers arranged circumferentially about the rotor in which each rotor chamber has a respective outlet port. Injectors are supported at circumferentially spaced locations about the housing so as to be arranged to inject hydraulic fluid in a generally tangential direction relative to the rotor axis into selected ones of the rotor chambers in which the injectors include at least one first injector and at least one second injector. A valve mechanism is configured to open any outlet port in which the respective rotor chamber is in communication with said at least one first injector and to maintain closed any outlet port in which the respective rotor chamber is in communication with said at least one second injector.
