Abstract
In an apparatus for producing, by the casting technique, a cooling means for narrow webs between adjacent cylinders in a cylinder block, separate cores are provided which are fitted at both ends into a water jacket core or into the bottom core in order to form cooling water channels in the webs. The cylinder blocks produced by the apparatus have in their web areas cooling water channels which are connected with the water jacket.
Claims7
An apparatus for producing, by the casting technique, a cooling means for webs between adjacent cylinders cast extremely close together in a cylinder block of a reciprocating engine whose cylinder walls are surrounded on both longitudinal sides and front sides of the cylinder block by a water jacket, with a jacket core to form the water jacket, comprising separate cores disposed in the web (5) to form cooling water channels (7, 7a, 7b) which bridge the two opposite longitudinal sides of said jacket core at the level of the cylinder combustion chamber, said separate cores being either fitted at both ends into said jacket core or fixed in an upper bottom core (11).
