Traction lighter impact structure sealing system

The invention relates to a sealing system for a traction igniter stroke structure, which traction igniter consists of a perforator with a safety pin and a trigger pin, which, when removing the pins, is adapted to strike a spring against a detonator to release the igniter.

A system as described above, in which the draw pin is adapted to press the sealing ring through the washer as an open structure, is already known from the prior art. The disadvantages of this system are the possible freezing of the striker when water and moisture come into contact with the sealing system, and the ingress of debris and dirt onto the sliding surfaces, which can cause the trigger pin to become stuck or difficult to remove. In addition, because the sealing ring is completely unprotected in contact with the outside air, it may spread and break or be otherwise damaged, making the traction igniter unreliable and posing a safety risk to its user, thus rendering it unusable.

The object of the invention is to eliminate the disadvantages caused by the previously known sealing system. This is achieved by placing the sealing ring in a recess in the body on which a washer is mounted, and these are covered by a protective cover which prevents contamination of the sealing system and damage to the seal.

According to the present invention, there is thus provided a system in which the impactor structure is sealed and protected by enclosing the sealing ring and washer with a protective cover so that they do not come into contact with the outside air, thereby effectively preventing splash water, dirt and debris from entering the structure.

In addition, oil can be placed under the protective cover, which also helps to prevent moisture and dirt from entering the sealing system and the impactor from sticking.

The choice of material of the protective cover and the quality of the surface facing the trigger pin can slightly adjust the tensile strength of the trigger pin, which is very essential for the operation of the igniter. The protective cover can be made of any material that can withstand shocks as well as temperature and humidity fluctuations, such as plastic, aluminum, etc. The protective cover can be roughened on the upper surface against the trigger pin, thus increasing the release resistance of the tow pin and thus no risk of detachment.

In addition, the assembly of a traction igniter with a sealing system according to the invention is more obvious and also safer, despite the addition.

The invention is described in more detail in the accompanying Figure 1, which shows a traction igniter according to the invention in a partially sectioned side view.

Figure 1 shows a traction igniter consisting of a striker (5) passing through the body (2), provided with a safety pin (3) and a traction pin (4), which strikes the detonator (6) to release the igniter when the pins are removed, and a sealing system (1). the sealing ring (8) is placed in a recess in the body on which the washer (7) is mounted, and these are covered with a protective crank (9).
