ABSTRACT:
A valve construction including an impingement plate and a nozzle structure mounted for relative movement therebetween, a first conduit for conducting fluid to the nozzle structure, the nozzle structure consisting of a plurality of cylindrical nozzles at the end of the conduit proximate the plate for projecting fluid from the conduit onto the plate or into the conduit (for reverse flow applications), the plurality of cylindrical nozzles providing a greater ratio of total metering area to projected nozzle area than is obtained by a single cylindrical nozzle. As an alternate to the plurality of cylindrical nozzles, a shaped noncylindrical nozzle may be used which has a higher ratio of metering area to projected area than that of a single cylindrical nozzle.
