Problems solved by technology

Attempts have been made in practice to counteract the risk of fire by installing an electric fuse inside the supply circuit of the coil winding, mainly in the form of a blown fuse, which in the event of a short circuit due to eroded parts of the insulating paint The fuse should open, i.e. the electrical circuit should be interrupted, however in practice this has proven to be insufficient to effectively counteract a possible fire hazard
It is therefore the case that although the blown fuse is opened, a (corrosion) fire starting from the correspondingly used actuating electromagnet may result due to a short circuit.

Embodiment Construction

[0016] exist figure 1 , the actuating device shown in longitudinal section is designed in the form of a so-called double-stroke solenoid, in particular a double-stroke proportional solenoid, which is mainly used for actuating hydraulic or pneumatic actuators not shown in detail valve. An analogous actuating electromagnet is described in DE 102005056816, also of the type single-stroke electromagnet, which can be used for the control of valves, but also for the release of safety devices, such as the release of headrests. exist figure 1 The operating device shown in has two coils 10, 12, wherein each coil 10, 12 is provided with a coil body 14, on which a coil winding 16 is laid, for example in the form of a painted electrical conductor, Preferably in the form of a copper wire. The design of the coils is so common in electromagnet technology that it will not be considered in detail here. Both coils 10 , 12 contain a pole tube 18 in which an armature part 20 is displaceable lo...

Abstract

The invention relates to a safety apparatus for avoiding a possible fire risk in an operating magnet which can be supplied with electric current, having at least one coil former (14) which is arranged in a housing (76, 82) and on which a coil winding (16) is fitted, and having an operating part (20, 36) which is at least partially guided in the coil former (14). As a result of at least parts of the operating magnet being equipped with active and / or passive safety means of the apparatus in order to effectively counteract the risk of fire, the safety means are no longer arranged remote from the actual event, for example in the form of a fuse in the electrical supply circuit, but rather directly at the location of the event where the possible fire or scorching situation can directly occur.

Description

technical field [0001] The invention relates to a safety device for avoiding a possible fire hazard on an energizable actuating electromagnet, comprising at least one coil body arranged in a housing and an actuation at least partially guided in the coil body Components on which a coil winding is mounted. Background technique [0002] A large number of embodiments of the aforementioned energizable actuating electromagnets are freely available on the market. For example, reference is made to the known solution according to DE 10 2004 017 089 B4 as a representative of the aforementioned actuating device, in particular in the form of a double-stroke electromagnet. The known solution is for the actuation of a valve comprising at least two coil windings arranged on each of a coil body between two annular flanges, the coil winding at least partly containing a pole tube, via which An armature part is movably guided, which transitions at one end via a magnetic spacer into a pole co...
