Abstract
A press-fit sleeve for sealing and cooling a component projecting through a fire deck opening in the cylinder head of an internal combustion engine is described. The press-fit sleeve includes a connecting point at a first end of the press-fit sleeve, said connecting point being designed for press fitting into an indentation at an end of the fire deck opening that faces away from a combustion chamber. Furthermore, the press-fit sleeve includes a radially inwardly protruding step at a second end of the press-fit sleeve lying opposite the first end. Between the first end and the second end, the press-fit sleeve includes a lateral surface which is closed in a fluid-tight manner and is or can be brought into contact with a water jacket surrounding the press-fit sleeve.
