International Classification:

B01D 33/06
B01D 33/70

US Classification:

2103601

Abstract:

A rotating separator has a housing preventing separated liquid carryover. A plenum between the annular rotating separating filter element and the housing sidewall has one or more flow path separating guides minimizing the flow of separated liquid to the outlet. The flow path guides may include one or more fins and/or swirl flow dampers and/or a configured surface.

B01D 46/24
B01D 46/26

Abstract:

Systems and methods for detecting a missing coalescing element in a CV system are described. In some arrangements, the described systems and methods prevent the assembly and/or re-assembly of the CV system without an appropriate coalescing element positioned within the CV system housing (e.g., during a coalescing element service operation). In some arrangements, the coalescing element depresses a spring-loaded component of a shaft that provides flow of bypass gases to the CV system. If the spring-loaded component is not depressed, significant restriction is introduced to the CV system, and an on-board-diagnostic system may detect high-crankcase pressure through existing crankcase pressure sensors and de-rate the internal combustion engine. In other arrangements, a spring-loaded mechanism within the shaft prevents a housing cover (e.g., a lid to the housing of the CV system) from being repositioned when a coalescing element is not installed within the housing.

International Classification:

B01D 46/00
B01D 46/24

Abstract:

A filter assembly for separating liquid from a fluid mixture that includes a filter housing with an inner surface, a filter element configured to separate a liquid from a fluid mixture and defining an outer surface, and a porous filter media. The filter element is positioned within the filter housing such that the outer surface of the filter element faces the inner surface of the filter housing. The porous filter media is attached to the inner surface of the filter housing to facilitate drainage of the liquid through the filter housing and prevent liquid carryover after the fluid mixture flows through the filter element.
