    • A system for controlling the delivery of a fuel gas to a burner apparatus comprises a gas-delivery duct (1) extending between an inlet opening (2) and an outlet opening (3), a pressure-regulator device (4) including a servo-valve in the duct, having a closure member (6) with diaphragm control (7), the diaphragm being subjected, on one side, to the pressure regulated by the regulator device (4) and, on the other side, to a calibration pressure established in a calibration chamber (8) of the regulator, as well as a calibration spring (9) provided in the calibration chamber and acting on the diaphragm (7). The system also comprises a delivery-pressure modulator unit (11) including a modulation valve with a valve seat (12) disposed in the duct (1) downstream of the pressure regulator (4) and cooperating with a respective closure member (13) operatively connected to actuator means arranged for the modulation control of the delivery pressure, as well as flow communication means between the calibration chamber (8) of the pressure regulator (4) and the modulator unit (11), for bringing into the chamber (8) a pressure signal that is correlated proportionally with the gas-delivery pressure so that the pressure regulated by the pressure regulator (4) is in turn correlated with the pressure signal.
    • 一种用于控制向燃烧器装置输送燃料气体的系统包括在入口(2)和出口(3)之间延伸的气体输送管道(1),包括伺服机构的压力调节装置(4) 在管道中,具有带有光阑控制(7)的关闭构件(6),所述隔膜在一侧受到由调节装置(4)调节的压力,另一侧经受校准 调节器的校准室(8)中建立的压力以及设置在校准室中并作用在隔膜(7)上的校准弹簧(9)。 该系统还包括输送压力调节器单元(11),其包括调节阀,调节阀具有设置在压力调节器(4)下游的管道(1)中的阀座(12),并且可操作地与相应的关闭构件(13)配合 连接到被布置用于调节输送压力的致动器装置以及压力调节器(4)的校准室(8)和调节器单元(11)之间的流动连通装置,用于进入腔室(8) 压力信号与气体输送压力成比例地相关联,使得由压力调节器(4)调节的压力又与压力信号相关。
