The cartridge base has a fixing flange and a circular ring-shaped metal sheet in contact with the fixing flange in the mounted state. A housing portion assignable to a housing of the air treatment device fixes, in a mounted state, the fixing flange to the housing portion. The fixing flange has a first flange fixing element and the housing portion has a first housing fixing element. The first flange fixing element and the first housing fixing element, in the mounted state, are engaged with one another. The fixing interface further has a locking element, wherein the locking element, in the mounted state, is engaged either directly and/or indirectly with the first flange fixing element and/or the first housing fixing element such that a degree of freedom of the fixing flange with regard to the housing portion or vice versa is locked.

A pressure regulating valve for an air supply system of a utility vehicle includes a housing having at least one compressed air connection communicating with at least one first pressure regulating chamber. The pressure regulating chamber has a variable volume delimited by at least one wall section of the housing and a first active pneumatic surface of a pressure regulating piston. In first position of the pressure regulating piston a first regulating channel is not connected to the pressure regulating chamber, and a second position of the pressure regulating piston is connected to the pressure regulating chamber. The pressure regulating piston includes a pin which rises out of the first active pneumatic surface of the pressure regulating piston. A second active pneumatic surface is located on an end of the pin. The pin is movably guided through the wall section in a pneumatically sealed manner.
