Hydraulic Turbine Motor

A hydraulic turbine motor assembly comprising:

• a pair of rotor housings;
• a rotor rotatably supported in each rotor housing for rotation about a common rotor axis, each rotor defining a plurality of rotor chambers arranged circumferentially about the respective rotor and each rotor chamber having a respective outlet port;
• a plurality of injectors supported at circumferentially spaced locations about each 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;
• a valve mechanism associated with each rotor housing which comprises an end wall of the respective rotor housing oriented transversely to the rotor axis and at least one outlet opening in the end wall, the outlet openings being configured to open at least some of the outlet ports of respective ones of the rotor chambers during communication of the respective ones of the rotor chambers with the injectors;
• and
• a common outlet chamber between the two rotor housings which is in direct communication with the outlet openings of the valve mechanisms of both rotor housings.
