Definitions

  • actuators are used to control internal combustion engines, which maintain a control between a minimum and a maximum position.
  • a typical implementation is carried out with two spring elements, one of which acts in the opening direction and one in the closing direction and of which in each case a spring element in a partial area does not act.
  • the spring acting in the closing direction is typically designed as a helical or spiral spring, while the spring acting in the opening direction can be executed as a helical and a leaf spring.
