    摘要: A method and an apparatus for determining the calorific value parameter describing the calorific value of a gaseous fuel. The apparatus comprises a test burner with a test combustion chamber. An air ratio sensor is arranged in an exhaust gas duct of the test burner and measures an air ratio signal that corresponds to the air ratio of the exhaust gas. As a function of the received air ratio signal, at least one setting signal is generated for a test supply unit via a test control unit. The setting signal controls the amount and/or the proportion of a gaseous fuel or an oxygen-containing gas that is supplied to the test combustion chamber. A calorific value sensor arrangement is provided in the combustion chamber and has an ionization sensor and, a temperature sensor. The sensor signal of the calorific value sensor is transmitted to a determination unit.

    摘要: A valve actuator (10) has a damping circuitry including a capacitive damping circuit (37), which is activated in the event of generator operation of the stepper motor (18). The damping circuitry, together with the motor winding (26), forms a resonance assembly LCR, which has the effect of stabilising and regulating rotational speed. The rotational speed of the stepper motor (18), running in generator operation, is held constant within limits, specifically without the control intervention of control circuitry. Therefore, the damping circuitry can operate even in the currentless state of the control system and is reliable regardless of external current supply. Fast closing is achieved, and excessively long post-running of the motor (18) is reliably prevented.

    摘要: A valve actuator (10) includes an electric motor (12) that opens, and also closes if need be, the valve via a gearing (15). A voltage supply device (19) has an input rectifier circuit and a buffer device (24) connected thereto, for example in the form of a capacitor C. From the voltage buffered by the capacitor C, a motor control circuit (25) obtains the energy for operating the electric motor (12). To prevent the valve (11) from being kept open too long after the voltage supply at the input (20) has been switched off, a switch-off device (34) is provided, which, after elimination of the voltage at the input (20), cuts off the energy flow from the voltage buffer device (24) to the electric motor (12).

    摘要: In a double seat valve (12), two preferably equally identical valve closure members (18, 20), said members being equally rigidly connected to another, and two preferably equally identical valve seats (19, 21) are provided. The first valve closure member (18) is arranged downstream of the first valve seat (19). The second valve closure member (20) is arranged upstream of the valve seat (21). In doing so, a radially interior sealing zone (37) becomes active on the first valve closure member (18). As opposed to this, a radially exterior sealing zone (38) becomes active on the second valve closure member (20).
