Abstract
A pneumatic turbine motor air chamber drives a pneumatic turbine to rotate through compressed air. The pneumatic turbine has a ring extended from inside thereof that has a plurality of barriers and forms a housing space to hold a speed regulator. The pneumatic turbine also has an air intake coupling hole leading to the housing space and at least one air discharge vent communicating with an air passage to discharge the compressed air. The ring is integrally formed with the pneumatic turbine to enhance operation steadiness of the pneumatic turbine.
Claims11
A pneumatic turbine driven by compressed air to rotate, the compressed air being received through an intake coupling hole and discharged through at least one discharge vent formed respectively on the pneumatic turbine, said pneumatic turbine comprising:
- a front cap;
- a rear cap;
- a turbine body which has a plurality of anchor pins at two sides engaging with a plurality of anchor holes formed on the front cap and the rear cap for the rotatable turbine body, causing the front cap and the rear cap to rotate together;
- and
- a ring which is extended from inside of the pneumatic turbine and has a plurality of barriers to form a housing space to house a speed regulator, the discharge vent communicating with an air passage to discharge the compressed air from the housing space.
A pneumatic tool having a pneumatic turbine motor, comprising:
- a combination of a base and a hand grip which has an air inlet and an air outlet to receive and discharge compressed air, and a housing compartment inside to hold a spindle which has an air channeling vent communicating with the air inlet and an opening to convey the compressed air;
- and
- a pneumatic turbine which is located in the housing compartment and has an intake coupling hole coupling with the spindle and a ring extended from inside thereof that has a plurality of barriers, the ring having a housing space communicating with the opening and housing a speed regulator, the pneumatic turbine having at least one discharge vent communicating with an air passage to discharge the compressed air, the pneumatic turbine including a front cap, a rear cap and a rotatable turbine body which has a plurality of anchor pins at two sides engaging with a plurality of anchor holes formed on the front cap and the rear cap for the rotatable turbine body, causing the front cap and the rear cap to rotate together.
