Abstract

1,207,398. Fluid-pressure servomotor systems. COMPRESSEURS BERNARD. Oct.10, 1967 [Oct.12, 1966], No.46192/67. Heading G3P. The speed of operation of a gas compressor is varied in relation to the rate of flow through an outlet 2 from a receiver 1 supplied by the compresser. When flow takes place through the outlet the pressure difference in a venturi 5 is communicated to a diaphragm 6 to lift a valve carried by the diaphragm out of engagement with a seat in a fixed partition 9 so that compressed air may pass from a line 37 through ports 36, 33, a manifold 32 and a port 34 to a space 20 to cause a diaphragm 8 to actuate a speed control F, such as a fuel-pump rank, for the compressor. Between the ports 36, 33, the compressed air flows through a chamber 17 and acts on a diaphragm 7 which is connected to the diaphragm 6 by a rod of constant length and closes the valve when the pressure in the chamber 17 is greater than the pressure differential on the diaphragm 6 by an amount corresponding to the ratio of the diaphragm diameters 29:30. The right hand side of the diaphragm 7 communicates with atmosphere through an aperture in a domed chamber 15 determining the effective diameter 30. An additional control B responsive to receiver pressure as well as flowrate may be provided.
