ABSTRACT:
An air starter having a rotary air motor and a drive pinion mounted on radially offset drive shafts in axially disposed housings which are connected by an intermediate common flange. The flange provides a pair of grooves which are concentric with each other and with one of the shafts. Air passages in the two housings are disposed to communicate with the grooves regardless of the relative angular orientation of the two housings. Also disclosed is pneumatically controlled main air valve which incorporates a lubricator for injecting a charge of lubricant into the incoming air stream as the valve opens and a shock absorber to regulate the closing movement of the main air valve against the bias of incoming air pressure.
