Abstract

A gas-compressing plant has a power source e.g. an electric motor 50, driving a rotary compressor of e.g. the meshing-screw type, 10 through a gear train 53, which may include two parallel shafts connected respectively to the male and female rotors 51, 52 of the compressor. The shafts include clutches 58, 59 and are attached to gears 56, 57 meshing (in series) with a gear 55 fixed to the output shaft of the motor. Control means are provided for operating the clutches to selectively connect the motor to either the male rotor or the female rotor and the gear ratios are selected so that two operating conditions are thereby provided for the compressor, a full speed condition and a part speed condition. To reduce power consumption the control means is responsive to pressure signals from a sensor positioned in the output line of a receiver to which compressed gas from the compressor is delivered, Figure 2 (not shown). Alternatively, the compressor is of the reciprocating- piston kind. <IMAGE>
