Combustion engine and mantle assembly therefore

Abstract

A combustion engine includes, a cylinder head including a controllable first engine valve arranged to selectively open/close a combustion chamber included in the combustion engine, a first valve actuator operatively connected to the first engine valve, which first valve actuator includes at least one inlet opening for pressure fluid and at least one outlet opening for pressure fluid, and a closed pressure fluid circuit, wherein the first valve actuator is arranged in the closed pressure fluid circuit. The combustion engine further includes a cylinder head chamber that forms part of the closed pressure fluid circuit and that is delimited by the cylinder head and at least a first cylinder head mantle, wherein the at least one outlet opening of the first valve actuator is in fluid communication with the cylinder head chamber. A mantle assembly for a cylinder head of a combustion engine is also described.
