Filed: 1929-06-04
Abstract: 313,001. Akt.-Ges. Brown, Boveri, et Cie. June 4, 1928, [Convention date]. Regulating. -Air is bye-passed back from the network supplied by a compressor when the delivery falls below the critical quantity, and while that action continues the speed of the compressor is kept artificially low. The compressor 1 is driven by the motor 2 and discharges into the network through the non-return valve 3. The bye-pass 4 contains a throttle valve 5, and the pressure regulator 10 and the valve 3 operate oil valves 9, 21 in the circuit of the oil which actuates the piston 13 of the motor controlling valve 14 with its interlock 16. The oil is supplied through the pipe 6; during normal operation the parts are in the positions shown and the valve 14 is regulated in such a manner that the air pressure remains constant. When the demand drops below the critical valve the non-return valve 3 closes and the piston 21 is moved below the pipe 8 to cut off the oil supply from the regulator 10 so that the valve 14 is set by its spring for the minimum motor speed. Compressed air flows back through the bye-pass 4 and throttle 5 thereby causing the pressure in the network to drop. This causes the pressure regulator 10 with its pistons 17, 18 to drop to effect communication between the oil pipes 11. 12 and the piston 13 raises the valve 14 as far as permitted by the interlocking device 16. When the air demand rises the pressure again drops and the piston 18 of the regulator 10 drops below the pipe 11; oil is then supplied through the pipe 19 to release the interlocking device 16. The regulating devices then operate normally until the compressor output and the net-work demand are in equilibrium again.
