Abstract

A multi-temperature refrigerator, of which the evaporators serving for cooling the compartments of different temperature can be activated separately through a 3/2-way solenoid valve, the solenoid valve being followed, for lowering the pressure of the refrigerant in relation to the respective evaporator, by a throttle line includes a marking on the throttle for mounting the line in a correct position on the solenoid valve. The invention forms the marking for the throttle lines with a separate component that can be applied to the throttle line positively and/or nonpositively.
