Patent number: 9982589Abstract: An intake manifold for a charged internal combustion engine has an intercooler provided with coolant connectors that is disposed in an intake manifold housing. The intake manifold housing has at least two housing parts including a basic housing part. The intake manifold housing is provided with at least one inlet and at least one outlet for charge air and is further provided with at least one passage for the coolant connectors of the intercooler. The intercooler is arranged between the at least one inlet and the at least one outlet so as to be flowed through by the charge air. The intercooler is fastened in the basic housing part by a fastening device such that the intercooler separates at least on one side of the basic housing part the at least one inlet seal-tightly from the at least one outlet.Type: GrantFiled: April 22, 2014Date of Patent: May 29, 2018Assignee: MANN+HUMMEL GmbHInventors: Gerrit-Tobias Speidel, Alexander Korn, Heinz Buehl, Karl-Ernst Hummel, Ulrich Dehnen, Klaus Kalbacher, Rebecca Weiss
