GAS/LIQUID SEPARATOR AND COMPONENTS; LIQUID DRAIN FLOW ASSEMBLIES; SYSTEMS OF USE ; AND, FEATURES; AND, COMPONENTS

摘要

According to the present disclosure gas/liquid separator assemblies, such as crankcase ventilation filter assemblies, and components are described. Also described are liquid flow control arrangements for facilitating liquid flow from a region of first effective pressure to a region of second higher effective pressure are described. In examples, the flow control arrangements are configured so they can be used in association with a gas/liquid separator, managing separation of liquids from crankcase ventilation gases, for example for internal combustion engines. Example arrangements are described, used with crankcase ventilation gas filter assemblies. Combinations of equipment, and various components usable in those combinations, are described.
