Abstract

A valve for adjusting a cooling fluid flow from a fluid source to a plurality of injection nozzles for cooling a plurality of pistons of an internal combustion engine is provided. The valve has a fluid duct for connecting the fluid source to the plurality of injection nozzles, and a valve element which is arranged so as to be movable, in particular displaceable, in order to change a flow cross-section of the fluid duct. The valve element can be moved into a first position, in which the flow cross-section is not influenced by the valve element.
