Abstract

A portable power supply unit has a parallelepiped casing in which there are installed a transformer-rectifier combination and a l.v. d.c. electric motor supplied from a battery or mains network. The shaft of the motor extends perpendicular to a side wall of the casing and has, at an end accessible through an opening of this wall, a power take-off. A reciprocating pneumatic compressor is installed in the casing with its shaft mounted coaxially in the motor shaft and is coupled to it by a clutch. A mechanism is provided to prevent the compressor shaft from being rotated by the motor shaft when a mechanical load is coupled to the power take-off.. By using coaxial motor and compressor shafts it is possible to enclose the motor and compressor in a very small space.
