NOVELTY - The accumulator housing comprises a degassing system (1), which is detachably disposed on a housing bottom (2) and has a base body (3) to be attached to the housing bottom of the accumulator, a guide arranged in the base body, a floating body provided in the base body and guided by the guide, and a cage, which is arranged in the base body and receives the guide. The base body has an opening in an upper section and is partially permeable to liquid in a lower section. The cage has an upper part (8) with a circular opening, and a lower part that is liquid-permeable.    USE - Housing useful in an accumulator for hybrid vehicles (claimed) and electrical vehicles for accumulating the galvanic cells, where the accumulator is hybrid accumulator, nickel metal hydride accumulator and lithium ion accumulator.    ADVANTAGE - The housing offers effective protection against excess gas pressure and against outer impurities to the accumulator, ensures high energy densities of the accumulator thus preventing explosion of the cells, maintains high-performance of the accumulator, and effectively prevents the penetration of the dust.    DETAILED DESCRIPTION - The accumulator housing comprises a degassing system (1), which is detachably disposed on a housing bottom (2) and has a base body (3) to be attached to the housing bottom of the accumulator, a guide arranged in the base body, a floating body provided in the base body and guided by the guide, and a cage, which is arranged in the base body and receives the guide. The base body has an opening in an upper section and is partially permeable to liquid in a lower section. The cage has an upper part (8) with a circular opening, and a lower part that is liquid-permeable. A seal (4) is provided along the opening of the upper part. The floating body is a ball. The guide comprises guide bars, which are arranged in a lateral surface of a cylinder. The cylinder has an inner diameter, which corresponds to the diameter of the ball. A sieve fabric is disposed at the upper part of the cage. The degassing system has a circular cross-section in a top view. A baffle plate is arranged below the base body.
