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 first and second injectors. A valve mechanism is configured to open any outlet port in which the respective rotor chamber is in communication with one of the first injectors and to maintain closed any outlet port in which the respective rotor chamber is in communication with one of the second injectors.
Claims15
A hydraulic turbine motor comprising:
- a rotor housing;
- a rotor rotatably supported in the rotor housing for rotation about a respective rotor axis, the rotor defining a plurality of rotor chambers arranged circumferentially about the rotor, each rotor chamber having a respective outlet port;
- a plurality of injectors 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, the injectors including at least one first injector and at least one second injector;
- and
- a valve mechanism configured to (i) open any outlet port in which the respective rotor chamber is in communication with said at least one first injector and (ii) maintain closed any outlet port while the respective rotor chamber is in communication with said at least one second injector such that any fluid injected into the rotor chambers by the at least one second injector serves only to build pressure within the respective rotor chamber.
A method of operating a hydraulic turbine motor having a rotor housing, a rotor rotatably supported in the rotor housing for rotation about a respective rotor axis and defining a plurality of rotor chambers arranged circumferentially about the rotor, and an outlet port for each chamber, the method comprising:
- injecting hydraulic fluid at circumferentially spaced injection locations about the housing in a generally tangential direction relative to the rotor axis into selected ones of the rotor chambers;
- intermittently opening the outlet port of each chamber during the injection of hydraulic fluid into the chamber at one or more injection locations and maintaining the outlet port of each chamber closed during the injection of hydraulic fluid into the chamber at one or more other injection locations.
