HEAD OF CYLINDERS Russian patent published in 2010 - IPC F02F1/24 

FIELD: engines and pumps.

SUBSTANCE: head of cylinders includes the following: section of lower support wall, section of external peripheral wall having the space inside itself, section of longitudinal wall, which passes and has in that cavity the inlet side where the outlet distributing shaft is located, the first sections of transverse walls, which are located on the inlet side, on which there are support sections for supporting the inlet distributing shaft on them, the second sections of transverse walls, which are located on the inlet side, on which there formed are the second support sections for supporting drive units of controlled valves on them, sections of transverse walls, which are located on the outlet side, on which there formed are support sections for supporting outlet distributing shaft on them. The second sections of transverse walls are located below the first sections of transverse walls in direction as to height from section of lower support wall. Sections of transverse walls of the outlet side are located above the second sections of transverse walls in direction as to height. Upper end surface of section of lower wall, which is located on outlet side, is located above the upper end surface of section of lower wall, which is located on inlet side in direction as to height.

EFFECT: increasing rigidity of inlet side and outlet side and maintaining rigidity balance between them.
