ABSTRACT:
An air motor 24 which may be employed in a mine drilling apparatus includes a hollow body 26 formed of a plastic material, and a driven shaft 38 rotatably supported by the body 26 and incorporating a valve assembly 34. The body 26 has opposing pairs of external faces 58 within which are mounted metal cylinder sleeves 29 which receive pistons 30. A cylinder head 31 of plastic material closes each cylinder 29 and a piston rod couples opposing pairs of pistons 30 and engages the shaft 38 so that power may be transmitted to this driven shaft 38.
