Engine with rotating valve assembly

A cylinder head assembly, comprising:

• a cylinder head having upper and lower cylinder head sections;
• at least one intake valve assembly pocket defined by the upper and lower cylinder head sections and at least one exhaust intake valve assembly pocket defined by the upper and lower cylinder head sections;
• at least one removable intake valve assembly positioned in the at least one intake valve assembly pocket and at least one removable exhaust valve assembly positioned in the at least one exhaust valve assembly pocket, the at least one removable intake valve assembly and at least one removable exhaust valve assembly each comprises:
• a housing having an internal cavity, an open top, and an open bottom, the open top and open bottom being in fluid communication with the internal cavity;
• a valve barrel positioned in the internal cavity and adapted for rotation therein, the valve barrel having an annular peripheral surface and an aperture extending transversely therethrough communicating with the peripheral surface on opposite sides;
• a first seal assembly positioned in the open top and a second seal assembly positioned in the open bottom, wherein the first and second seal assemblies each include a seal having a sealing surface in mating engagement with the peripheral surface and an aperture extending therethrough, the aperture having a size and shape substantially equal to the aperture in the valve barrel to permit flow therethrough;
• and
• wherein when the aperture of the valve barrel is in alignment with the apertures of the first and second seal assemblies, gas is permitted to flow between the upper and lower cylinder head sections through the removable valve assembly.

A removable valve assembly, comprising:

• a valve barrel positioned in the internal cavity and adapted for rotation therein, the valve barrel having an annular peripheral surface and an aperture extending transversely therethrough communicating with the peripheral surface on opposite sides;
• a first seal assembly positioned in the open top and a second seal assembly positioned in the open bottom, wherein the first and second seal assemblies each include a seal having a sealing surface in mating engagement with the peripheral surface and an aperture extending therethrough, the aperture having a size and shape substantially equal to the aperture in the valve barrel to permit flow therethrough, wherein each of the first and second seal assemblies further include a backer plate connected to the seal;
• first and second ring seals, wherein the first ring seal is positioned between the first seal assembly backer plate and a first cover of the valve assembly and the second ring seal is positioned between the second seal assembly backer plate and a second cover of the valve assembly;
• and
• wherein when the aperture of the valve barrel is in alignment with the apertures of the first and second seal assemblies, gas is permitted to flow through the removable valve assembly.
