<p>Injection system, wherein the undepicted controlled generator is the controlled converter (5). The converter (5) is mechanically joined with magnetostrictive transformers (4) and (7), e. g. by weld joint. Magnetostrictive transformer (4) is a part of a needle (2). Magnetostrictive transformer (7) is a part of a body (1) of injection. The needle (2) runs through the channel (6) of the body (1) of the injection. To the channel (6) there is connected the undepicted fuel income. The end of the needle (2) is embedded in the saddle of the die (3). The movement of the needle (2) does not depend on the fuel pressure, but it depends on the converter (5) function. Through the converter (5) the size of a needle (2), injection and also the body (1) of an injection is controllably changed. The resulting clear opening between the end of the needle (2) and the die (3) is given by shortening the needle (2) and by elongating the body (1) of the injection provided of relevant different chemical composition of the material and also of the needle (2) and the body (1), from the view of magnetostrictive characteristics of these materials. The injection device can be used in devices for the control of the flow of injected medium, e. g. into combusting motors.</p> |
