  • Ventilation module for a transmission of a motor vehicle, in particular of an electrically driven motor vehicle
    Patent number: 12297898
    Abstract: A ventilation module for a transmission of a motor vehicle, in particular an electrically driven motor vehicle, comprises a housing with a connection opening on the transmission side and an atmosphere opening open to the environment, wherein a gas channel connecting the connection opening to the atmosphere opening in a gas-conducting manner is provided in the housing. A float valve with a float arranged in a float chamber, a valve body and a valve opening is arranged in the gas channel, wherein liquid entering the float chamber through the atmosphere opening causes the float to rise, wherein when a certain liquid level in the float chamber is exceeded the float, the valve body connected to the float, closes the valve opening and thereby the gas channel in a liquid-tight manner.
