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.

Abstract: A process for the purpose of the thermostatic control of a sample fluid to be analyzed, as well as reagents and optionally the solvents necessary for performing analyses in an automatically functioning analyzer, wherein the sample container containing the sample fluid as well as the cells containing the reagents are placed in a rack made from good thermally conducting material. The rack is fixed in the analyzer at the individual processing stations between two side walls. At least one of the side walls is heated, so that the rack is thermostatically controlled and, consequently, so is the sample fluid and the reagents.
