ABSTRACT:
Connection arrangement for pressure medium ducts in a diesel engine for connecting at least two ducts (2,3), included in the same pressure medium system, located parallel in the longitudinal direction of an engine block (1) and being in successive order in the flow direction of the pressure medium circulation of the system, either together or separately with one or more devices or units, for instance with coolers (8,9), located on the side of the ducts and included in the pressure medium system in question so that a desired direction of flow is accomplished and that said connection prevents the pressure medium flow of the inlet side and of the outlet side of the device from being mixed with each other. The arrangement includes a set of different, preferably cylindrical, hollow duct assemblies (4) to be installed in a connection chamber made in the engine block at a desired location. The connection chamber connects the ducts with each other (2,3) and includes a connection aperture (5) on the side of the ducts for connection thereof to said device or unit (8,9). The duct assemblies (4 ) include two or more flow guidance apertures (4a,4b) being located so as to accomplish different flow alternatives. The connection chamber is then provided with one or more sealing surfaces (5a,6a,7,7') arranged to cooperate with the duct assembly (4) selected in each case so that the duct assembly (4) is sealed according to need to the connection aperture (5), to the wall between the ducts and/or to the upper and/or lower walls of at least one of the ducts.
