The fluid channel is connected in fluid communication with the interior of a filter element of the filter system. A seal for the cover has a first sealing ring and a second sealing connected to each other by flanks. The filter system has a housing with a housing part that is closable by the cover. A filter element is exchangeably arranged in the housing, and the fluid channel of the cover is connected in fluid communication to the interior of the filter element.

Abstract: Provided is a filter that filters air flowing from the filter to a downstream component, while preventing fluid from flowing from the filter to the downstream component and preventing a substance, such as urea or fuel, entering the filter from the downstream component from degrading the filter element in the filter. The filter includes a filter element having an interior surface defining an inner chamber and a standpipe extending through the inner chamber and terminating at a point that allows air that flows from outside the filter element through the filter element and into the inner chamber to flow into the standpipe and out of the filter, while preventing fluid flowing from the opposite direction through the standpipe from entering the filter element.

Abstract: An exhaust gas aftertreatment system for an engine can perform manual regeneration control for regenerating a particulate removal filter by increasing the engine rotation speed. The system can suppress the engine rotation speed increase while maintaining the exhaust gas temperature required to regenerate the particulate removal filter. The system can set the target engine rotation speed to a first set value when a regeneration instruction signal from a manual regeneration switch is received. When, although the engine rotation speed falls within a predetermined engine rotation speed range including the first set value that is the target engine rotation speed for a predetermined time period, the exhaust gas temperature does not reach the filter's regeneration temperature within the predetermined time period, the target engine rotation speed is repeatedly reset by being increased from the first set value by a predetermined rotation speed.

Abstract: A moisture separator where a corrugated plate 43 is provided with a collecting plate 49 formed to cover a flat portion 74 and an upstream end of a slope portion disposed on a downstream side of the flat portion 74. The collecting plate 74 has an opening which opens to an upstream side in the direction of the wet steam flow S1. The collecting plate 49 is fixed to the slope portion at a base end. Between the collecting plate 49 and a body portion of the corrugated plate, a pocket section 47 and a drain duct section 48 are formed. The moisture contained in the wet steam S1 turns into droplets and enters the pocket section 47 and the drain duct section 48 from the opening of the collecting plate 49 and falls down the pocket section 47 and the drain duct section 48 respectively by gravity.

Abstract: An oil flow management system reduces the amount of oil directed from an aircraft engine to the environment outside of the aircraft, even when the aircraft is in inverted flight. This decreases the amount of oil that becomes attached to exterior surfaces of the aircraft fuselage. A gaseous mixture including air and oil is directed from the aircraft engine to a separator, which separate the mixture into a gaseous component and an oil component. The oil component is directed from the separator to a reservoir via a unidirectional valve. When in a first orientation, the unidirectional valve allows oil to flow from the separator to the reservoir. However, when in a second orientation, the unidirectional valve blocks oil from flowing from the reservoir to the separator.

Abstract: A trap device includes means for separating a liquid compound from a waste stream exhaust from a process chamber, means for collecting the liquid compound separated from the waste stream, means for selectively isolating the collected liquid compound from the waste stream, and means for evaporating the collected liquid compound to return the compound in gaseous form to the waste stream. This can enable a volatile liquid to be collected at a defined location, isolated from the waste stream, and, when so desired, returned to the waste stream in the form of a gas for subsequent abatement.

Abstract: An improved vehicle air filter includes a cylindrical housing having a continuous outer wall, a releasable bottom wall and an open top in communication with an interior air-delivery chamber. Circumferentially disposed about the outer wall are a plurality of conical air-intake tubes, each having an inlet opening in fluid communication with a hollow interior. The lower end of each tube is positioned immediately above a collection pan formed on the releasable bottom wall. An arcuate air conduit extends from the upper end of each tube to the air-delivery chamber. As air enters each tube, it flows along a cyclonic path to force entrained particles against the interior surface of the tube and downwardly into the collection pan. Meanwhile, the purified air flows upwardly through the air conduits and into the air-delivery chamber for distribution to the vehicle engine.

Abstract: Disclosed are coalescer systems for coalescing a liquid phase dispersed in a gas phase. The disclosed systems include a filter element which, when installed in the system, contacts and moves a valve to an open drainage position to permit flow of liquid through the system. In the disclosed systems, the filter element and valve also are configured such that under excess pressure conditions the valve permits the gas phase to bypass filter media of the filter element. In particular, the disclosed coalescer systems may be utilized in a CV system in order to remove oil mist from gas in the CV system.

Abstract: A method of separating particles from particle laden air having a multiple stage separator in which the first stage comprises a generally cylindrical chamber having a hollow central member extending axially from one end thereof with openings in its wall remote from the one end. The first separation step is achieved by introducing air tangentially into the chamber near its one end, establishing a rotating mass of air in the chamber causing heavier than air particles to migrate to the outer regions of the chamber. Suction is applied to the interior of the central member to cause an axial movement of air through the chamber such that particles near the walls of the chamber tend to continue in a generally rotational and axially progressive path into a particle collecting region of the chamber, while relatively particle-free air is drawn radially inwardly.

To discharge dust (11) accumulated in the air filter (5) a carrier airflow (10) is provided in a flow channel (16) and the filter housing (7) is fluidly connected with the aid of a discharge tube (13) to the flow channel (16). For a dosed metering of dust (11) from the filter housing (7), a shutoff member (14) is provided and the shutoff member (14) clears or closes the fluid connection between the flow channel (16) and the filter housing (7).

Abstract: A secondary separator stage for separating material conveyed in a fluid stream. A material collecting receptacle includes an inlet conduit and an exhaust vent. The stream of fluid with materials flow via the inlet conduit into the receptacle. An exhauster located upstream on the inlet conduit removes the majority of the fluid within the fluid stream prior to the stream flowing into the receptacle. The remaining portion of the fluid entering the receptacle is removed via an exhaust vent. A rotating plate allows the fluid in the receptacle to pass therethrough but blocks passage of any conveyed materials.

Abstract: A versatile waste disposal apparatus for separating and disposing the liquid waste from vacuum cleaning of soiled carpets. The air, liquid and accumulated dirt in a mixture from a conventional vacuum cleaner are separated in one large tank, and the filtered liquid is passed on either to an integrated or non-integrated smaller tank with cutoff, air venting, and pump controls. The filtered liquid is ultimately passed on to a wastewater system so that the tanks are empty after use. The waste disposal apparatus can be integrated with a dwelling's central vacuuming system and operated on house current. The apparatus can be installed in a vehicle and powered by the vehicle's battery.
