초록 ▼

An apparatus, such as a ventilator, for regulating the flow-through amount of a flowing medium, such as a gas, has a valve with a variable orifice operated by a first regulating circuit with negative feedback. The regulating variable generated by the first regulating circuit controls the size of the orifice so that the difference between a desired value and an actual value for the flow-through amount os minimized, toward zero. To achieve rapid changes in the flow-through amount with a high regulating precision, at least one further regulating circuit is provided to which the regulating variable of the first regulating circuit is supplied as the desired value. The actual value for the further regulating circuit may be the measured position of the closure element for the orifice. The bandwidth and the gain can be optimized for each regulating circuit. The energy consumption can be lowered by current recovery and battery operation can be simplified, in the event of a power outage.

An apparatus for regulating the flow-through amount of a flowing medium comprising: a valve having an input connectable to a source of flowing medium, an output for said flowing medium, a valve opening disposed between said input and said output, and movable closure means for opening and closing said valve by varying the size of said valve opening; means for calculating a first actual value, corresponding to the actual flow-through amount of said flowing medium through said valve opening; means supplied with a control signal for controlling the position of said closure means in said valve opening dependent on a characteristic of said control signal; first regulator means, supplied with a rated value for said flow-through amount and connected to said means for calculating a first actual value to receive said first actual value therefrom, for generating a first regulating variable by negative feedback for use in controlling the position of said closure means so that a difference between said rated value and said first actual value is driven toward zero; means for calculating a second actual value, corresponding to the actual position of the said closure means in said opening; second regulating means, supplied with said first regulating variable as a rated value and connected to said means for calculating a second actual value to receive said second actual value therefrom, for generating a second regulating variable by negative feedback for use in controlling the position of said closure means so that a difference between said first regulating variable and said second actual value is driven toward zero; means for calculating a third actual value, corresponding to an actual value of said control signal characteristic; and third regulating means, supplied with said second regulating variable as a rated value and connected to said means for calculating a third actual value to receive said third actual value therefrom and connected to said means for controlling, for generating a third regulating variable forming said control signal for controlling the position of said closure means so that a difference between said second regulating variable and said third actual value is driven toward zero.
