Turbine motor for pneumatic tools

Abstract

A turbine motor for a pneumatic tool, comprising a casing, a rotor and an axis. Compressed air enters the casing through an inlet and is directed towards blades of the rotor in a radial direction, so that torque is exerted on the axis. The blades of the rotors are to a large part hit by compressed air, each for an extended time, so that high effectivity and good efficiency result, allowing for operation at high speed and under high load.

1 . A turbine motor for a pneumatic tool, comprising: 
 a casing, surrounding a chamber, with an air inlet and an air outlet being attached to said casing;    a rotor, disposed inside said chamber, performing a rotational movement driven by compressed air from said air inlet; and    an axis, carrying said rotor, having a rear end borne by said casing and a front end passing through said casing, from which torque is taken.    
   
   
       2 . The turbine motor for a pneumatic tool according to  claim 1 , wherein a stator is inserted between said rotor and an inner wall of said casing.  
   
   
       3 . The turbine motor for a pneumatic tool according to  claim 2 , wherein said stator has a plurality of stator blades.  
   
   
       4 . The turbine motor for a pneumatic tool according to  claim 2 , wherein said stator is radially oriented and placed opposite said air inlet.  
   
   
       5 . The turbine motor for a pneumatic tool according to  claim 3 , wherein said stator is radially oriented and placed opposite said air inlet.  
   
   
       6 . The turbine motor for a pneumatic tool according to  claim 2 , wherein an air whirling device surrounds said stator.  
   
   
       7 . The turbine motor for a pneumatic tool according to  claim 1 , wherein in said chamber a shield and an outlet passageway are placed along airflow towards said stator.  
   
   
       8 . The turbine motor for a pneumatic tool according to  claim 1 , wherein said axis has a plurality of bearings, so that said axis and said rotor are borne inside said shield of said rotor.  
   
   
       9 . The turbine motor for a pneumatic tool according to  claim 7 , wherein said axis has a plurality of bearings, so that said axis and said rotor are borne inside said shield of said rotor.  
   
   
       10 . A turbine motor for a pneumatic tool, comprising: 
 a casing, surrounding a chamber, with an air inlet and an air outlet air being attached to said casing;    a rotor, disposed inside said chamber, performing a rotational movement driven by compressed air from said air inlet;    an axis, carrying said rotor, having a rear end borne by said casing and a front end passing through said casing, from which torque is taken;    a rear casing, placed at a rear end of said casing, closely surrounding said rotor and blades thereof; and    an air direction adjusting knob, placed close to said air inlet and allowing, by an axial or an angular movement, to switch directing of incoming compressed air onto said rotor between forward and reverse directions.    
   
   
       11 . The turbine motor for a pneumatic tool according to  claim 10 , wherein a valve is installed at said air inlet, allowing to switch incoming airflow on and off.  
   
   
       12 . The turbine motor for a pneumatic tool according to  claim 3 , wherein said plurality of stator blades have adjustable orientations.  
   
   
       13 . The turbine motor for a pneumatic tool according to  claim 3 , wherein said plurality of stator blades are turnably set on a plurality of blade supports.  
   
   
       14 . The turbine motor for a pneumatic tool according to  claim 12 , wherein said plurality of stator blades are turnably set on a plurality of blade supports.
