This patent describes a mechanical seal which is designed to have an external quench supply within compact dimensions and also be readily assembled and disassembled. The quench is provided through port (40) and circulates around the outside diameter of the seal faces (3, 10) and into the narrow space on the periphery of the static seal ring (30F). The leakage of quench fluid is prevented by a packing ring (4). Although not specifically mentioned in the English abstract, this seal appears to have the sealed product on the inside diameter.

The aim of intake and exhaust system design is to control the transfer of acoustic energy from the sources and its emission by the system with minimal loss of engine performance. A rational design process depends on the adoption of a design methodology based on predictive modelling of acoustic behav
