NOVELTY - The degassing system comprises a labyrinth pin (14) having a pin wall, in which channels (17) are provided, which extend from the pin interior toward outlets disposed in an axial section of the pin wall, a labyrinth corso (7) having a corso wall extending in the mounted stated about the axial section of the pin wall such that a gap (19) is formed in the axial section between the bolt wall and the corso wall, a gas-permeable membrane (5) disposed on the top of the labyrinth pin, and a baffle plate (8) arranged in the installation condition with distance below the labyrinth corso.    USE - Degassing system for a housing of an accumulator (claimed) such as hybrid accumulator, nickel-metal hybrid accumulator and lithium-ion accumulator, useful in the galvanic cell, in hybrid vehicles and electric vehicles.    ADVANTAGE - The degassing system can effectively protect the accumulator against a positive pressure caused by an overload of the galvanic cell or a short circuit as well as against penetration of spray-water, dust or other contamination, thus enabling to provide high-performance accumulator with high energy densities.    DETAILED DESCRIPTION - The degassing system comprises a labyrinth pin (14) having a pin wall, in which channels (17) are provided, which extend from the pin interior toward outlets disposed in an axial section of the pin wall, a labyrinth corso (7) having a corso wall extending in the mounted stated about the axial section of the pin wall such that a gap (19) is formed in the axial section between the bolt wall and the corso wall, a gas-permeable membrane (5) disposed on the top of the labyrinth pin, and a baffle plate (8) arranged in the installation condition with distance below the labyrinth corso. The membrane opens with a pre-defined pressure difference at the membrane, and is designed as an open screen cloth. A seal is arranged in the installation condition on the labyrinth pin. The degassing system has circular cross-section areas. The channels have cross-section areas of 50-500 mm2. The labyrinth pin comprises an external thread and the labyrinth corso comprises an internal thread cooperating with the external thread. The degassing system further comprises a paraxial opening, through which the components of the degassing system are connected with one another by a screw connection.
