Abstract: A passive pulse generator can be connected to a line in order to activate a safety fitting in a nuclear power plant. The line can be closed by a closure element. In the event of a temperature change in the vicinity of the pulse generator, the closure element is actuated solely as a result of a thermal volume change of an actuating element, so that the line is released. The pulse generator therefore activates the fitting passively, without additional control pulses. A method for activating a fitting with a passive pulse generator is also provided.

Abstract: Given the disadvantages inherent in known prior art, the object is to create a procedure and suitable injection nozzle to achieve a rotationally symmetric distribution of fuel during entry into the combustion chamber. In addition, the object is to achieve a high atomization quality, in particular at the start of the injection process already, an optimal injection progression while the nozzle opens, and a variation in injection quantity. To achieve this object, it is proposed that the fuel be introduced into the swirl chamber where its radius is largest. While the nozzle outlet opening is closed, a radial velocity component directed toward the axis of the swirl chamber is imparted to the fuel flow to go along with the peripheral velocity component. The fuel flow is removed from the swirl chamber where its radius is smallest, concentrically to the valve needle, wherein the removal of fuel from the swirl chamber is slowed or completely interrupted during the injection phase.

Abstract: A pin puller combines an actuator with an anti-friction release mechanism, according to a bilaterally symmetric geometry. The anti-friction tension release mechanism ensures that only negligible friction forces need to be overcome to operate the tension release mechanism. Thus, the actuator is isolated from the large tension force that bears on the tension release mechanism. The bilateral symmetric aspect of the structure provides for mechanical redundancy, so that, in the event that one half of the pin puller fails, it is sufficient that the other half operate properly for the tension to be successfully released. This pin puller avoids premature release because it is not susceptible to static electricity or electromagnetic radiation. The pin puller also avoids generation of large shock waves due to its slow speed of operation and because of the gradual release interaction of mechanical parts within the anti-friction release mechanism.
