Abstract

A pressure compensation module includes a first pressure chamber having a first displacer device with a first displacer internal volume. A second pressure chamber includes a second displacer device with a second displacer internal volume. An intermediate space between the first pressure chamber and the first displacer device is a first compensation volume. An intermediate space between the second pressure chamber and the second displacer device is a second compensation volume. The first compensation volume is fluidically connected to environment surrounding the first pressure chamber by a first compensation connection. The second compensation volume is fluidically connected to environment surrounding the second pressure chamber by a second compensation connection. The first displacer internal volume is fluidically connected to the second compensation volume by a first internal volume connection. The second displacer internal volume is fluidically connected to the first compensation volume by a second internal volume connection.
