1. A scroll compression device including at least:

  • a first scroll element having a first base plate and a first spiral wrap extending from the first base plate,a second scroll element having a second base plate and a second spiral wrap extending from the second base plate, at least one of the first and second scroll elements being configured to perform an orbiting movement in relation to the other one of the first and second scroll elements, the first and second scroll elements intermeshing with each other and delimiting compression chambers,a sealing device arranged in an end face of the first spiral wrap of the first scroll element and having a sealing surface configured to cooperate with the second base plate of the second scroll element,wherein the sealing device is configured to allow fluid flow from an upstream compression chamber to a downstream compression chamber through the sealing surface when the pressure in the upstream compression chamber exceeds the pressure in the downstream compression chamber, and the sealing device is configured to prevent fluid flow from a downstream compression chamber to an upstream compression chamber through the sealing surface when the pressure in the downstream compression chamber exceeds the pressure in the upstream compression chamber.
