Abstract: An exhaust system includes a cylinder head having a plurality of exhaust ports. Integrally formed with the cylinder head are a plurality of independent and separate tubes. The tubes are cast, molded or otherwise integrally formed with the exhaust ports of the cylinder head. The cylinder head and tubes eliminate the need for an exhaust flange, welding the tubes to the exhaust flange and securing the exhaust flange to the cylinder head. As a result, the exhaust system has less weight and improved performance over prior art cylinder head and exhaust assemblies.

Abstract: An in-line, pressure balanced universal expansion joint for a piping system has a central bellows and opposite first and second end bellows secured to the opposite first and second ends of the central bellows. A first gimbal assembly pivotally links the outer end of the first end bellows to the second end of the central bellows. A second gimbal assembly links the outer end of the second end bellows to the first end of the central bellows. Each gimbal assembly has a gimbal ring pivotally linked to the outer end of the respective end bellows via a first linkage and to the respective end of the central bellows via a second linkage for pivotal movement about two perpendicular pivot axes.

Abstract: An expansion joint assembly for use in a piping system has a central tubular bellows and opposite first and second end bellows secured to respective opposite first and second ends of the central bellows. Outer tubular ends of the respective first and second end bellows are linked to the second and first ends, respectively, of the central bellows via first and second elongate link members. The first link member is pivotally connected to the outer end of the first end bellows at one end and secured to the second end of the central bellows at its opposite end. The second link member is pivotally connected to the outer end of the second end bellows at one end and secured to the first end of the central bellows at its opposite end.
