Document Type and Number:
Japanese Patent JP3730571
Kind Code:
B2
Abstract:
An air motor, especially for a screwer, comprises an air rotor which is rotatably supported in a motor cylinder and comprises a plurality of longitudinal slits extending in the longitudinal direction of the rotor for radially guiding lamellae, the air rotor and motor cylinder having formed thereinbetween chambers which can be brought into communication with an air inlet and/or an air outlet. To achieve a high efficiency of the motor together with a more uniform accelerating power, a reduced sound level and less wear while the exhaust air throttling measures are reduced at the same time, the motor cylinder comprises an inner chamber of an essentially triangular cross-section, one chamber each being formed between air rotor and a triangle tip.
