Activated carbon filter unit for a tank system

摘要

Activated charcoal filter unit for a tank system consisting of a housing (13) which can flow through at least one chamber (31, 32) intended to receive an activated charcoal filling and in which a housing (13) incorporating this chamber, according to the illustration of a ventilation or rinsing operation or a leak test with the tank system, the ambient atmosphere and a connection for generating a negative pressure connectable flow path is set up, the flow path with a first valve (6) for opening and closing the connection of the flow path with the ambient atmosphere and a second valve (9) is equipped for opening and closing the connection to the connection for generating a negative pressure, characterized by a control module (15) which is detachably connected to the housing (13) and in which at least the valves (6, 9), a check valve (10) , which in the lead to the connection for generating a negative pressure renden connection, a sensor (12) for detecting the pressure of the gas atmosphere within the tank system, a sensor (4) for detecting the temperature of the gas atmosphere within the tank system and an air filter (7) are included.
