Coaxial valve system

Abstract

An interposed coaxial valve system designed for internal combustion engines. The system comprises a single main valve integrating two coaxial valves: an interior valve and an exterior valve. The interior valve may move independently from the exterior valve during engine operation. The system minimizes spatial occupancy for internal combustion engine valves. By interposing the interior valve within the exterior valve, the system achieves a compact and efficient design. The system may also comprise adjacent intake and exhaust ports to promote heat transfer between the two ports.

         2 . The coaxial valve system as claimed in  claim 1 , wherein the exterior valve comprises:
 an upper portion;   and   a lower portion;   the upper portion is adjacent to the center portion;   a center portion adjacent to the lower portion wherein the upper portion and the lower portion are opposite to each other by separation by the center portion.   
     
     
         3 . The coaxial valve system as claimed in  claim 2 , wherein the interior valve also comprises:
 a bottom plate connected to an opposite end of a rod.   
     
     
         4 . The coaxial valve system as claimed in  claim 2 , wherein
 the plate of the interior valve is configured to engage with the upper portion of the exterior valve;   and   the bottom plate of the interior valve is configured to engage with the lower portion of the exterior valve.   
     
     
         5 . The coaxial valve system as claimed in  claim 1 , further comprising an interior valve spring wherein said spring is circumferentially positioned around the rod of the interior valve. 
     
     
         6 . The coaxial valve system as claimed in  claim 5 , further comprising an exterior valve spring wherein said spring is circumferentially positioned around a central portion of the exterior valve. 
     
     
         7 . The coaxial valve system as claimed in  claim 1 , wherein an upper portion of the exterior valve comprises:
 an upper face;   a cutout; and   a lip;   
       the upper face being the topmost upwardly facing surface of the exterior valve;
 and 
 the lip proximate an uppermost portion of the upper portion of the exterior valve. 
 
     
     
         8 . The coaxial valve system as claimed in  claim 7 , wherein the system is contained within a housing. 
     
     
         9 . The coaxial valve system as claimed in  claim 8 , wherein the housing comprises an intake chamber and an exhaust chamber
 the intake chamber is a cavity within the housing; and   the exhaust chamber is a cavity within the housing.   
     
     
         10 . The coaxial valve system as claimed in  claim 9 , wherein the housing further comprises an intake port and an exhaust port wherein the intake port is an open passageway to the intake chamber and the exhaust port is an open passageway to the exhaust chamber. 
     
     
         11 . The coaxial valve system of  claim 1 , wherein the interior valve comprises a rod, wherein the top plate is integrally connected to one end of the rod, and wherein the exterior valve comprises a through hole proximate the central axis through which the rod of the interior valve transverses a length of a central portion of the exterior valve. 
     
     
         12 . The coaxial valve system of  claim 1 , wherein the cutout is in an upper portion of the exterior valve and the plate is a top plate. 
     
     
         13 . A coaxial valve system comprising an interior valve and an exterior valve wherein;
 the interior valve comprises an elongated shape having a central axis;   the exterior valve comprises an elongated shape having a central axis;   the central axis of the interior valve and the central axis of the exterior valve comprising a coaxial alignment wherein the interior valve is interposing within the exterior valve;   the interior valve and the exterior valve have the capability to linearly move independently along the coaxial axes; and   the interior valve and the exterior valve being linearly actuated by a plurality of cams coupled to a camshaft,   wherein the interior valve comprises a plate,   wherein the exterior valve has a cutout,   wherein the plate fits within the cutout,   wherein a shape of the plate and a shape of the cutout are such that movement of the interior valve is limited to a movement along the central axis of the interior valve and such that the interior valve cannot rotate within the exterior valve.   
     
     
         14 . The coaxial valve system of  claim 13 , wherein the cutout is in an upper portion of the exterior valve and the plate is a top plate. 
     
     
         15 . The coaxial valve system as claimed in  claim 13 , wherein the exterior valve comprises:
 an upper portion;   a lower portion; and   a through hole;   the upper portion is adjacent to the center portion;   a center portion adjacent to the lower portion wherein the upper portion and the lower portion are opposite to each other, separated by the center portion;   the center portion comprising a duct and a plurality of openings;   the duct is a cavity located within the center portion of the exterior valve;   the plurality of openings traverse through the exterior valve; and   the through hole extending the length of the exterior valve proximate the central axis.   
     
     
         16 . The coaxial valve system as claimed in  claim 13 , wherein said system is contained within a housing comprising:
