Pressure-wave machine in vehicle - has by=pass valve between gas passages opening in proportion to excess inlet pressure

摘要

The pressure-wave machine has a compartmented rotor in bearings in a housing and between guide housings for hot gas and air. The gas housing (1) has a first passage (2) connected to an engine exhaust outlet, and a second (3) connected to an exhaust outlet system, together with a valve between the two. The valve opens up a connection (6) between the passages immediately a threshold value in the first one is exceded. The cross-section of this connection increases dependent on the degree of excess pressure in the first passage. USE/ADVANTAGE - Pressure wave machine in vehicle is compact, and accommodates sensitive components inside, thus giving greater protection. from damage.
