Embodiment Construction

[0102] figure 1 Shown is an electrochemical power source which is provided with a housing 2 in which a magnetic valve arrangement 4 is inserted in a housing opening 3 . In this case, the electrochemical power source 1 can have at least one electrochemical current generator and / or at least one electrochemical energy store as component parts, wherein the components of the electrochemical power source 1 are arranged in the housing interior 5 Inside.

[0103] figure 2 The magnetic valve device 4 shown in has a locking element 6 configured as a cover or flap. Furthermore, the magnetic valve device 4 is provided with a frame element 7 by which the magnetic valve device 4 can be fixed in the housing opening 3 . Furthermore, the locking element 6 is connected to the frame element 7 via a hinge element 8 , wherein the hinge element 8 is designed such that the locking element 6 can be pivoted away from the housing opening 3 and thus opens the housing opening 3 . Or open up.

Abstract

A valve apparatus (4) is provided for a housing (2) of an electrochemical current source (1). Furthermore, the magnetic valve apparatus (4) is provided for, among other things, battery housings, fuel cell housings as well as chemical or biological reactors. As a result of using a magnetic valve apparatus (4) as an excess pressure valve, the housing (2) can be designed to operate safely even after years of use, and in addition, the valve apparatus (4) can automatically change back into the closed position after an opening and a pressure degradation and can thus build up again a protection against the penetration of fluids into the inner space (5) of the housing without external action.

Description

technical field [0001] The invention relates to a valve device for a housing of an electrochemical power source, a housing comprising a magnetic valve device and an electrochemical power source comprising a housing with a magnetic valve device. Furthermore, the invention relates to the use of the magnetic valve arrangement in, inter alia, (battery) battery housings, fuel cell housings and chemical or biological reactors. Background technique [0002] Large battery systems or other electrochemical storage such as supercapacitors are increasingly used. They are used in particular for back-up emergency, ie emergency power supply. They are used, for example, in electric or hybrid vehicles, traction systems for industrial use, such as forklift trucks or robots, in ground transportation vehicles, and in sports and recreational vehicles. Other aspects also apply to railways and aviation. [0003] In all these applications, the battery usually consists of a large number of indivi...
