ABSTRACT:
A cooling system for cooling sleeves (2) fixed to a carrier plate (1), by means of a fluid which is passed from a fluid inlet (15) to a fluid outlet (22) by way of fluid conduits (7, 14, 10, 11, 21) supported by means of the carrier plate (1). The fluid conduits (7, 14, 10, 11, 21) include main supply conduits (7) and supply conduits (10, 11) which extend approximately transversely with respect to each other. The supply conduits extend in a mutually parallel relationship and are arranged in pairs in the carrier plate (1) and are connected to a row of sleeves (2) by way of intake (16) and discharge conduits (17). The row of sleeves (2) is so disposed between the supply conduits (10, 11) of a pair such that each sleeve (2) is connected to both supply conduits (10, 11), and fluid communication is interrupted (plug24) in at least the one supply conduit (10) of the pair substantially at the middle of its longitudinal extent (l).
