The direction of pressure is the direction in which a compressive force acts on a body. In theory, the line of action and sense of direction describe the direction of a force.
This applies not only to pressure, but also to other physical forces. The complete description of a force requires information on its direction and strength. Bodies tend to slide or compress in the direction of pressure.
#1 Definition of pressure direction
#2 Meaning of the pressure direction
In sealing technology, the pressure direction is particularly relevant for the design of installation spaces and the dimensioning of sealing elements.
They are essentially exposed to two types of pressure. In addition to the deformation force of the sealing surfaces, media can also exert pressure.
Both types of pressure must be taken into account in the design. Media pressure with alternating directions places particular stress on seals.
