Abstract
A braking mechanism for a rotary apparatus having a housing adapted to receive a pressurized fluid and a rotor rotatably mounted in the housing. The braking mechanism enables the rotor to rotate in the housing in response to the receipt of the pressurized fluid and inhibits the rotor from rotating in the absence of the receipt of the pressurized fluid.
Claims13
A rotary apparatus comprising:
- a housing adapted to receive a pressurized fluid and to discharge the received pressurized fluid so as to create an exhaust pressure;
- a rotor mounted in said housing and being rotatable therein in response to the receipt of said pressurized fluid;
- and
- braking means, responsive to the absence of said exhaust pressure, for preventing said rotor from rotating.
A rotary apparatus comprising:
- a housing adapted to receive a pressurized fluid and to discharge the received pressurized fluid so as to create an exhaust pressure;
- a rotor rotatably mounted in said housing;
- and
- braking means for enabling said rotor to rotate in said housing in response to said exhaust pressure and for inhibiting said rotor from rotating in the absence of said exhaust pressure.
A rotary apparatus comprising:
- a housing having an internal cavity and being adapted to receive a pressurized fluid into said internal cavity;
- a rotor rotatably mounted in said internal cavity;
- means for creating a predetermined exhaust pressure in said internal cavity upon the receipt of said pressurized fluid;
- and
- braking means, responsive to said predetermined exhaust pressure, for enabling said rotor to rotate in said internal cavity and, in the absence of said predetermined exhaust pressure, for inhibiting said rotor from rotating.
A rotary apparatus comprising:
- a housing adapted to receive a pressurized fluid and to discharge the received pressurized fluid so as to create an exhaust pressure;
- a rotor rotatably mounted in said housing;
- and
- braking means for automatically enabling said rotor to rotate in said housing in response to said exhaust pressure and for automatically inhibiting said rotor from rotating in the absence of said exhaust pressure.
In a reaction turbine-type motor having a housing adapted to receive a pressurized fluid and to discharge the received pressurized fluid so as to create an exhaust pressure, and a rotor mounted in said housing and being rotatable therein in response to the receipt of said pressurized fluid, the improvement comprising:
- braking means, responsive to the absence of said exhaust pressure, for automatically preventing said rotor from rotating.
