Abstract

A low-speed L.P. stage 1 and one or more high-speed H.P. stages 2 disposed in a common housing 3 are driven separately through gearing 4 by a single adjustable-speed driving means 5 which may be a frequency-controlled three-phase motor, a D.C. motor fed with rectified current from a single- or three-phase supply, an I.C. engine or a turbine. <IMAGE>
