In Figur 2 ist ein Ausführungsbeispiel der Mittel (5) zur automatischen Anpassung der Gaszufuhr über ein im Strömungsweg zum Brenner (4) angeordnetes Zwei-Wege-Ventil (8) gezeigt. Figur 2a zeigt die Ausbildung und Anordnung des Ventils (8) für den Einsatz vor einem Brenner (4) mit Mischkammer (9). Die Mischkammer (9) ist mit zwei Düsen (10) bestückt. Eine Düse (10) ist für den Erdgasbereich ausgebildet, die andere Düse (10) für den Flüssiggasbereich. Im Strömungsweg des Gases zur Mischkammer (9) ist das Zwei-Wege-Ventil (8) angeordnet, das durch einen Steuerkolben (11) eine der beiden Gasdüsen (10) zur Mischkammer (9) freigibt. Der Steuerkolben (11) wird durch einen Elektromagneten (12) bewegt.

Figure 2a shows the design and arrangement of the valve (8) for use in front of a Burner (4) with mixing chamber (9). The mixing chamber (9) is equipped with two nozzles (10). A Nozzle (10) is designed for the natural gas area, the other nozzle (10) for the LPG area. The two-way valve is in the flow path of the gas to the mixing chamber (9) (8) arranged by a control piston (11) one of the two gas nozzles (10) for Mixing chamber (9) releases. The control piston (11) is actuated by an electromagnet (12) emotional.

The The position of the two-way valve (8) can be changed using a selector switch or button Control panel or a code entry via the keyboard (7) can be switched.
Figur 3 zeigt ein Gasventil (13) mit elektromagnetisch veränderbarem Druckregler. Da für die Anpassung der Gaszufuhr an Erdgas oder Flüssiggas nur zwei Druckeinstellungen erforderlich sind, ist die Druckreglermembran (14) anstelle der sonst üblichen Stellschraube mit einem elektrisch betätigbaren Hubmagneten (15) ausgebildet, der in zwei Stellungen bewegbar ist. Je nach Gasart wird über den Hubmagneten (15) und seine Stellung ein entsprechender Düsenvordruck erzeugt, so daß nur eine Düse für Erdgas oder Flüssiggas erforderlich ist. Werden mehr als zwei Druckeinstellungen benötigt, ist der Hubmagnet (15) mit einem federvorgespannten Kolben (16) ausgebildet, der in gewissen Grenzen durch einen Elektromagneten (17) mit variabler Gleichspannug oder PWM-Signal angesteuert wird. So sind beliebige Stellungen und damit in einem Gasbereich beliebige Drücke einstellbar. Bei Ausfall des Elektromagneten (17) wird der Druckregler, der mit einem Ventilsitz (18) gekoppelt ist, geschlossen. Somit sind auch die Sicherheitserfordernisse erfüllt. Der Gasdtuckregler ist vorzugsweise hinter dem Gasventil am Gaseintritt und vor der Gasdüse am Ausgang angeordnet. Er besteht aus der auf der Kolbenstange (16) beweglichen Membrane (14) und dem Regelventil. Der Kolben wird vom Elektromagnet (17) nach unten gedrückt. Dem entgegen wirkt die Feder unter dem Ventil (18), so daß das Ventil (18) schließt, wenn der Elektromagnet (17) ausfällt. Über die Feder, die auf die Membrane (14) wirkt, werden Gasdruckschwankungen ausgeregelt. FIG. 3 shows a gas valve (13) with an electromagnetically variable pressure regulator. As for the Adjustment of gas supply to natural gas or LPG requires only two pressure settings are, the pressure regulator membrane (14) instead of the usual screw with a electrically actuated solenoid (15) is formed, which is movable in two positions. Each Depending on the type of gas, the solenoid (15) and its position are used to determine the corresponding position Nozzle pre-pressure generated, so that only one nozzle for natural gas or LPG is required. If more than two pressure settings are required, the solenoid (15) has one spring-biased piston (16) formed within certain limits by a Electromagnets (17) with variable DC voltage or PWM signal is controlled. So are any position and thus any pressure can be set in a gas range. In the event of failure of the electromagnet (17) the pressure regulator, which is coupled to a valve seat (18), closed. This means that the security requirements are also met. The gas pressure regulator is preferably behind the gas valve at the gas inlet and in front of the gas nozzle at the outlet arranged. It consists of the diaphragm (14) and movable on the piston rod (16) the control valve. The piston is pressed down by the electromagnet (17). Against that the spring acts under the valve (18) so that the valve (18) closes when the electromagnet (17) fails. Gas pressure fluctuations are caused by the spring that acts on the diaphragm (14) corrected.

Dazu wird über einen in der Bedienblende angeordneten Wahlschalter (6) ein Trockenprogramm für den Betrieb des Gerätes ausgewählt. Über einen weiteren Wahlschalter oder eine Tastatur (7) erfolgt die Eingabe für die Gasart, so daß die Anpassung der Düsen bzw. entsprechende Einstellung des Düsenvordruckes am Druckregler automatisch erfolgen kann. Die Eingabe ist nur jeweils bei der Erstinbetriebnahme am jeweiligen Standort des Gerätes erforderlich. Eine Änderung der Einstellung ist in der Regel nur bei einem Standortwechsel des Gerätes erforderlich.Figure 4 shows a gas-heated clothes dryer with a program selection and Control device (1), a device for regulating the heating operation (2) and one Device for supplying gas (3) to a burner (4).
