摘要： An integrated pressure regulator is provided with three stages configured to reduce an extreme tank pressure down to a typical working pressure. The regulator is configured to supply a steady working pressure until the tank pressure is reduced to little more than the working pressure itself. Stages of the pressure regulator are integrated into a body and arranged to minimize regulator mass and volume. A thermally-triggered pressure relief device may be included with a triggering time adapted to enhance the safety of smaller cylinders that may be used, e.g., in aerial applications.

摘要： A pressure relief device includes a housing member having an inner space, a piston member provided in the inner space of the housing member, and a fusible member provided in a region below the piston member. The piston member includes an upper end region formed at an upper end in the up-down direction (H), and a connection region which is formed below the upper end region and extends downward from the upper end region while being connected to the upper end region. A first width (W1) of the upper end region in a left-right direction (A) is equal to a second width (W2) of the connection region in the left-right direction (A) or less than the second width (W2).

摘要： A thermo valve has a valve chamber disposed inside a housing and open to a first flow path through an opening. Second and third flow paths open into the valve chamber. A thermo-element that can move back and forth axially inside the valve chamber in response to fluid temperature opens and closes the second and third flow paths and is biased in a direction that blocks the flow paths by a coil spring. A valve element that is a bypass valve that opens and closes an opening that connects the first and third flow paths inside the valve chamber and communicates the first and third flow paths is disposed in the opening. The coil spring is also used to bias the valve element in a direction that blocks the flow paths.

摘要： A nuclear engineering plant has a containment, whose interior chamber is subdivided by a wall into a systems chamber and an operating chamber which is accessible during normal operation. The containment ensures a particularly high operational reliability, in particular also in incident situations, in which hydrogen is released in the systems chamber. For this purpose, a number of overflow openings are provided in the partition wall, the respective overflow opening is closed by a closure element of a closure apparatus which opens automatically when a trigger condition associated with the respective overflow opening is reached. Closure apparatuses are provided which open both as a function of pressure and independently of pressure. The closure apparatus furthermore has a closure element containing a bursting film or a bursting diaphragm. The closure apparatus is configured such that it frees the overflow opening automatically when a predetermined environment-side trigger temperature is reached.
