Abstract
A speed-reduction transmission for a reciprocating piston aircraft engine, in which the oil-collecting space of the speed-reduction transmission housing arranged between the piston engine and the propeller is connected with the oil-collecting space of the crankcase of the engine by way of an overflow pipe; the upper part of the speed-reduction transmission housing is in communication with the air space of the crankcase by way of a vent pipe; the vent pipe and the overflow pipe are so arranged that their functions are interchanged during upside-down flights of the aircraft and the oil volume disposed in the bottom of the transmission housing remains constant.
