摘要
The scroll compression device includes a first scroll element (11) having a first base plate (13) and a first spiral wrap (14); a second scroll element (12) having a second base plate (15) and a second spiral wrap (16), one of the first and second scroll elements (11, 12) 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 (11, 12) intermeshing with each other and delimiting compression chambers (17); and a sealing device (28) arranged in an end face (19) of the first spiral wrap (14) and having a sealing surface configured to cooperate with the second base plate (15). The sealing device (28) 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 (28) 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.
