Abstract: The invention relates to a directly controlled magnetic valve, comprising a fixed core which is located in a magnet and a moving armature to which a seal plate is fixed by means of a tappet. When the valve is activated, the seal plate interacts with a valve seat which is fixed to the housing. Corresponding sealing elements are provided on the seal plate and on the valve seat and at least the tappet and the seal plate have bores which are situated centrally in the longitudinal direction. The aim of the invention is to produce a magnetic valve which has a large nominal width allowing a small construction volume, a low power requirement, rapid pressure compensation and rapid switching. To this end, second sealing elements which correspond with each other are provided on a front face which is permanently connected to the armature and on an adjacent face which is fixed to the housing.

Abstract: An electrical assembly for an oil burner nozzle has a heating element and a conductive foil assembly for supplying current to the heating element. The conductive foil assembly has a base material in the form of an electrically insulating sheet configured to extend from the heating element in the oil burner nozzle to an access position accessible from outside the oil burner nozzle. Foil conductors are disposed on the electrically insulating sheet and extend from the access position to the heating element. Another electrically insulating sheet selectively covers the foil conductor in a sandwiched arrangement. The conductive foil assembly is folded around the heating element and portions of the foil conductors are placed into electrical contact with the heating element via non-insulated areas of the foil conductors provided by the selective covering.

Abstract: A fuel oil burner with a fuel heater and an electromagnetic valve has a pipe member with an external diameter, a first end portion adjacent a fuel feed duct and a second end portion adjacent a nozzle. The first end portion is connected with the fuel feed duct and the second end portion is connected with the nozzle. In the pipe member are members for conducting and for preheating the fuel. The electromagnetic stop valve is arranged between the preheater and the nozzle. Electrical contacts adapted for the preheater and the stop valve are provided at the pipe member in the vicinity of the first end portion. Electrical connections to the stop valve and the preheater are within the external diameter of the pipe member. The fuel oil burner is very compact, compatible and reliable.
