Abstract
A speed governor for engines which comprises a rotary hollow shaft receiving exhaust fluid at one end, a conduit and nozzle assembly connected at the other end of the rotary hollow shaft and including a needle valve, a turbine housing in which at least one turbine disposed on after another in the flow path of said exhaust fluid, a turbine drive shaft associated with said turbine, respectively, a movable annular member disposed about said rotary hollow shaft for movement in the axial direction of the rotary hollow shaft and a spring-loaded link connected to said needle valve at one end and engaging said annular member at the other end.
Claims7
A fluid driven engine comprising:
- a rotary hollow cylindrical shaft adapted to be rotatably mounted on a stationary fluid feed conduit for rotation around the axis of the stationary feed conduit;
- a turbine housing coaxially secured to said rotary hollow cylindrical shaft for rotation with said cylindrical shaft and having at least one turbine rotatably mounted therein;
- nozzle means in said housing connected between said cylindrical shaft and said turbine housing for directing fluid from said cylindrical shaft under pressure against said turbine for rotating said turbine, the reaction to the impact of the fluid on said turbine causing said housing to rotate;
- a turbine shaft driven by said turbine;
- an engine output shaft;
- and
- transmission means connected between said turbine shaft, said housing and said engine output shaft and transmitting the rotation of said turbine and said turbine housing to said engine output shaft and limiting the speed of rotation of said turbine housing to a speed slower than the rotational speed of said turbine.
The engine as claimed in claim 8 in which said first turbine shaft has the greatest length and the smallest diameter, said second turbine shaft has an intermediate length and diameter and is hollow and coaxial around said first turbine shaft, and said third turbine shaft has the shortest length and largest diameter and is hollow and coaxial around said second turbine shaft.
