The invention relates t a heat exchanger, in particular a radiator for motor vehicles comprising a black consisting of tubes and ribs and a lower and upper collection chamber, the lower collection chamber having several chambers which are separated from one another by partitions and between which a fluidic connection can be established. If necessary, by means of a displaceable actuator via connection orifices (17, 18, 19) that are located in a connection channel (16). According to the invention, the actuator is configured as a piston (30) that can be displaced axially between an open and a closed position and the cross-sections of the connection channel (16) and the piston (30) taper from the exterior to the interior in the vicinity of the connection orifices (17, 18, 19).
A heat exchanger, in particular a radiator for motor vehicles, with one or more header boxes at least one header box having a plurality of chambers which are divided off from one another by means of partitions and between which a fluid connection can be made, as required, by means of a movable actuating member via connecting orifices arranged, in particular, in a connecting duct, wherein the actuating member is designed as a piston adjustable axially between an open and a closed position, and the cross sections of the connecting duct and of the piston are designed differently in the region of the connecting orifices in particular decreasingly from a first outermost connecting orifice to a second outermost connecting orifice.
A valve arrangement with a connecting duct and with connecting orifices which are arranged in a housing and between which a fluid connection can be made, as required, by means of a movable actuating member, wherein the actuating member is designed as a piston adjustable axially between an open and a closed position, and the cross sections of the connecting duct and of the piston are designed differently in the region of the connecting orifices in particular decreasingly from a first outermost connecting orifice to a second outermost connecting orifice.
