Abstract: A pneumatic generating device has a valve sleeve, a valve core, a piston pin, and a guiding assembly. The valve sleeve has a sleeve chamber and an input end. The valve core is mounted rotatably in the valve sleeve and has an axial hole and an annular groove. The annular groove is defined around the valve core. The piston pin is mounted moveably in the axial hole and has an end extending out of the input end of the valve sleeve and combined with a sealing cap. The guiding assembly is combined rotatably with the valve core and has a signal member and a guiding tube. The signal member is held in the annular groove in the valve core and has a passage communicating with the sleeve chamber. The guiding tube is connected with signal member and communicates with the passage in the signal member.

Abstract: A pneumatic motor has a housing, an axle, and multiple blades. The axle is rotatably mounted in the housing and has multiple blade recesses. The blades are mounted respectively and moveably in the blade recesses. Each blade has an inner side edge. The inner side edge is mounted in a corresponding one of the blade recesses. The inner side edge of each one of at least half of the multiple blades has a straight segment and a rectangular tab. Each one of the blade recesses which holds the blade having the straight segment and the rectangular tab has a bottom having a straight segment and a tab hole.
