<p>A head port sealing gasket 56 is disclosed for use in a barrel compressor 40 which has a head 42 fitted within a barrel casing 44. The sealing gasket 56 has a curved outer surface 60 matching the curvature of the inner diameter of the barrel casing 44. An O-ring is fitted within an O-ring groove 62 in the outer surface to sealingly engage the inner surface of the barrel casing. The sealing gasket 56 is received within a port 68 formed into the outer cylindrical surface of the head. A chamfer 92 on the end of the casing 44 allows the head and sealing gasket mounted thereon to be slid into the proper position within the barrel casing without damage to the O-ring. <IMAGE></p> |
