Appl. No.:

6/083766

International Classification:

F02N 708

Abstract:

A compact starter for internal combustion engines features a torque transfer assembly in which a drive motor and a drive pinion are mounted in side-by-side, parallel relation. The power shaft of the drive motor and the pinion shaft of the pinion are coupled together in driving engagement by a gear train assembly including a housing having coupling surfaces which permit the drive motor and drive pinion to be positionally rotated independently with respect to each other for accomodating the mounting clearance requirements of different engines. The gear train assembly features an idler gear which transfers torque from a motor pinion mounted on the power shaft and a pinion gear mounted on the pinion shaft. The idler shaft is confined between the drive motor and the torque transfer housing in a compact arrangement which permits efficient torque transfer in the side-by-side, parallel mounting arrangement without interferring with independent mounting adjustment of the drive motor relative to the drive pinion. The structure of the drive pinion shaft is simplified by a bearing support arrangement in which one end of the pinion drive shaft is journaled within the pinion housing, with the opposite end being journaled within the gear housing on a roller bearing assembly mounted on an extended bearing surface of the drive gear and confined within the gear train housing.

Abstract:

A rotary vane air or gas motor is provided with a primary exhaust port having an exhaust fluid throttling valve therein for controlling motor speed. The motor includes a secondary exhaust port for discharging exhaust fluid flow from the motor expansible chambers after cutoff of the primary exhaust port. A flow sensing vane member is movably disposed in a flow passage in communication with the secondary exhaust port and is responsive to flow variations to actuate the exhaust fluid throttling valve by connecting linkage. The interconnected exhaust fluid throttling valve and flow sensing vane function as a motor speed limiting governor.
