Abstract
The invention provides, at the end of a pipe which extends a valve being part of an exhausting device for pressure-relieving a pressurized fluid, a nozzle which is exactly at the input of a hood, the convergent portion of said nozzle reducing its exit section so as to make it substantially double the maximum passageway section through the valve.
Claims3
An exhausting device for pressure-relieving a high-pressure apparatus comprising in combination an exhaust conduit comprising a tubular downstream portion and a generally cylindrical shaped upstream portion which is of smaller diameter than said tubular downstream portion, said conduit having a widened inner end in the form of a hood open to ambient, said generally cylindrical upstream portion being preceded by a convergent section connected to said hood, and being followed by a divergent section defining said tubular downstream position, a valve controlled discharge pipe having means for connecting said pipe to a high-pressure apparatus at one end with the other end positioned within said hood, a jet nozzle having a convergent-divergent configuration integral with said discharge pipe and forming a constricting outlet end for said pipe which projects into said hood while being inwardly spaced from the wall thereof, the convergent section of said jet nozzle being connected to said pipe and the divergent section opening into said exhaust conduit.
