Abstract:
The invention relates to a device for separating a gas-liquid mixture, in which the liquid portion exists in the form of small particles, especially for ventilating a crankcase of an internal combustion engine, by separating and coagulating the liquid particles on a target area. The liquid mixture, after acceleration in acceleration openings provided for this purpose, impacts the target area at an approximately right angle. The aim of the invention is to improve the aforementioned device in such a manner that it allows as high a degree of separation as possible for different sized volume flows of mixtures. For this purpose, the number and/or the cross-sections of the acceleration openings (5, 6) is varied, depending on the volume flow of mixtures, between a small complete cross-section for a low volume flow and a large complete cross-section for a large volume flow.
Abstract:
A portable, hand-held, combustion engine powered working machine comprises a tool unit (1) including a rotatable working tool (3), and a machine unit (2) including an internal combustion engine (11), an assembly (16) for supplying air and fuel to the engine, and an air cleaning system, which comprises a filter assembly (10) including at least two filters (84, 85), referred to as pre-filter (84) and main filter (85), for cleaning the air that shall be supplied to the engine. The pre-filter is accommodated in an upper filter chamber (86) between a top cover (83) and a pre-filter bottom (9), and the main filter is accommodated in a lower filter chamber under the pre-filter bottom, said lower filter chamber being defined by the underside of the pre-filter bottom, a second filter bottom (125) at a distance from the pre-filter bottom, and a closed, circumferential wall (120) between the pre-filter bottom and the second filter bottom, said closed, circumferential wall forming a downwards directed protrusion on the underside of the upper filter bottom.
Abstract:
A high conductivity particle filter provides a flow path to subject a fluid stream to a series of turns. The turns require an abrupt directional change for the fluid stream. Traps are positioned in proximity to the turns to capture particles, which have greater inertia than the fluid. The flow path may be a spiral or a series of parallel paths. A cross sectional area of the flow path may be progressively decreased to increase flow velocity and particle inertia.

A self-governing continuously variable inertial gas-liquid separator has an axially movable valve controlling axial flow through a nozzle orifice, and a variable flow controller upstream of and controlling the valve.
Abstract:
A precursor delivery system (100) includes a flow path (104) from a precursor container (102) to a reaction space (110) of a thin film deposition system, such as an atomic layer deposition reactor. A staging volume (114) is preferably between precursor container (102) and reaction space (110) for receiving at least one dose of precursor material from precursor container (102), from which a series of pulses is released toward reaction space (110). Precursor material is typically vaporized after loading in precursor container (102), by heating or reducing the pressure inside precursor container (102). A vacuum line (156) preferably coupled to precursor container (102) bypasses reaction space (110) for reducing pressure inside precursor container (102) without drawing particles into reaction space (110). A high conductivity particle filter having inertial traps may be included, preferably between precursor container (102) and a staging volume (114), for filtering particles from the precursor material.
Abstract:
A cyclonic fluid separator of the type comprising a tubular throat portion (4) in which a fluid mixture is accelerated to a subsonic or supersonic speed and thereby expanded and cooled down so that condensable components condense and/or solidify and then swirl into a diverging fluid outlet section (5) that comprises an aliter secondary outlet (6) for condensables enriched fluid components and an inner primary outlet (7) For condensables depleted fluid components comprises swirl imparting vanes (2) that protrude tram a central body (1) that extends through at least part of an inlet section of the separator, wherein the central body (1) has, at a location upstream of the throat portion (4), a larger aliter width (2Ro max) than the smallest inner width (2Rn min) of the throat portion (4).
Abstract:
An air cleaning system for a vehicle includes an inertial separator (12) for filtering contaminated air, which then enters a vehicle cooling system (14) positioned to receive the filtered air exiting from the inertial separator (12), and a clean air diverter (16) positioned to receive a portion of the filtered air and direct the filtered air to an engine (20) and/or cab (44).
Abstract:
A moisture collector (10) for collecting moisture from moisture containing air exiting from an air conditioning system in substantially a first flow direction is disclosed. The collector comprises a moisture collector housing (12) defining a volume. An inlet (14) extends into the volume for receiving the moisture containing air from the air conditioning system while substantially moving in the first flow direction. An outlet (16) extends out of the volume for exhausting substantially moisture free air. A device for redirecting the moisture containing air is positioned within the volume and upstream of the outlet. At the device, moisture is removed from the moisture containing air for forming the substantially moisture free air. An air passageway is defined in the volume for directing the substantially moisture free air from the device for redirecting toward the outlet along with the moisture. A volume for collecting the moisture (22) is provided. A device is positioned in the air passageway in the path of the moisture free air for directing the moisture moving with the moisture free air into the volume for collecting downstream of the outlet.
