Abstract
A pressure compensation device for compensating an internal pressure in a housing of an electrochemical device includes: at least one gas-permeable membrane for gas exchange between an interior of the housing and surroundings of the electrochemical device; and a valve body that can be transferred from a home position resting on a valve seat into a use position remote from the valve seat, the valve body including a gas throughflow opening that is sealed by the gas-permeable membrane.
Claims14
A pressure compensation device for compensating an internal pressure in a housing of an electrochemical device, comprising:
- at least one gas-permeable membrane configured for gas exchange between an interior of the housing and surroundings of the electrochemical device;
- a valve body configured to be transferred from a home position resting on a valve seat into a use position remote from the valve seat, the valve body comprising a gas throughflow opening that is sealed by the gas-permeable membrane;
- and
- a pressure generating mechanism configured to counteract the internal pressure and to hold the valve body in the home position, provided that the internal limiting pressure is not exceeded, the pressure generative mechanism further configured such that, when the internal limiting pressure is exceeded, the pressure generating mechanism releases the valve body such that it can move to the use position,
- wherein when the valve body is in the use position, the pressure generating mechanism is remote from and does not act on the valve body.
