Abstract (en)
[origin: EP0638381A2] The invention relates to a cast housing, especially for hydraulic conveying means, having regions which can be subjected to pressure and/or are to be sealed off and having passages designed to carry the medium to be delivered and cast simultaneously in the housing. It is envisaged that the regions should be assigned at least one pressurizable pressure space which exerts a reaction pressure on the regions, the pressure space being formed simultaneously with the casting of the housing (26), and the passages furthermore being formed by cores (16) which remain at least partially in the housing (26) after it has been cast. <IMAGE>
