ASSEMBLAGE DE SOUPAPE ET DE FILTRE

摘要

A valve and filter assembly. The assembly has an elongated tubular structure defining a path of fluid flow and this tubular structure carries between its ends a valve seat surrounding the path of fluid flow. A valve member coacts with the valve seat and is moved to and from a closed position engaging the valve seat for controlling the fluid flow. A filter extends across the interior of the tubular structure for filtering the fluid flowing therethrough, and this filter has an upstream surface toward which the fluid flows and a downstream surface away from which the fluid flows after passing through the filter. In communication with the upstream surface of the filter is a collecting chamber into which filtered matter drops by gravity so as to be collected at a location beyond the path of fluid flow.
