<p>The invention relates to a linear motor actuated valve arrangement for a gas installation, the valve arrangement including a valve body 1 with at least one gas inlet 3 and at least one gas outlet 5 assigned to the gas inlet. At least one gas outlet can be closed by means of a medium-controlled or flame-controlled safety valve element 17 and can also be reduced in cross-section and/or closed by means of a further valve element 10 arranged on a non-rotating shaft 8. The shaft is actuated by a linear motor 6, and may have a star-shaped (splined) cross section, which slides in a sleeve 9, which may be Teflon. The linear motor may be gas-tight, and may be a step motor. The further valve element may be arranged on the shaft in a moveable manner under an applied spring force from a spring 12, thus permitting the shaft to be pushed through the seated further valve element in order to lift the safety valve element from its valve seat. The invention also relates to a common valve body for multiple adjacent identical valve arrangements in which the gas inlets of all valve arrangements are connected to a common gas supply. The common valve body may be formed from an extruded profile, such as aluminium, and the valve arrangement may be used in a gas installation such as for example, burners used on cooker hobs.</p> |
