A particulate filtration device is suggested, comprising an inlet for an inflow of a gas stream which is particle-laden, an outlet for an outflow of the gas stream having a significantly reduced particulate load, a main filter section, which is arranged within a flow path of the gas stream between the inlet and the outlet and which comprises a filtration medium, and a prefilter chamber, which is arranged upstream of the main filter section and which comprises an inertial filter element, having several perforations, wherein the perforations of the inertial filter element are arranged within the flow path of the gas stream in such a way that when the flow path of the gas stream is passing through the perforations, an inertial separation of the particulates from the mean flow path of the gas stream is achieved.

An internal combustion engine includes a blow-by gas processing device. A cylinder head cover of the internal combustion engine is provided with a joint portion including a connection port to which a connection pipe is connected and a throttle portion having a passage sectional area smaller than a passage sectional area of the connection port. The joint portion is communicated with an inside of a cylinder head and a space in the joint portion serves as an oil separator. A pressure sensor is connected to the space in the oil separator via a connection passage. The connection passage includes a first pipe, a second pipe, and a chamber including a first connection port to which the first pipe is connected and a second connection port to which the second pipe is connected. The first connection port and the second connection port are open toward the same direction in the chamber.

The invention relates to an oil separating device (10) for crankcase ventilation of an internal combustion engine, comprising a carrier (11) comprising a gas inlet line (12) for flowing blow-by gas (13) having an inlet end and an outlet end, and a gap-defining element (15), wherein at least one annular gap (5, 6) is formed or can be formed between the gap-defining element (15) and the outlet end of the gas inlet line (12). A baffle wall (7, 8) is arranged downstream of the annular gap (5, 6). The oil separating device (10) comprises a circumferential wall (18), which surrounds the outer circumference of the gap-defining element (15) and is fixed relative to the carrier (11).

A water extractor for an environmental control system of an aircraft includes a separation mechanism configured to divide an airflow into a first airflow and a second airflow. The separation mechanism includes an inlet conduit, a body in fluid communication with the inlet conduit, and at least one coalescing feature arranged within an interior of the body. A water extraction vessel is arranged in fluid communication with the separation mechanism. The water extraction vessel includes a first portion for receiving the first airflow and a second portion for receiving the second airflow. The first portion is configured to collect and remove water from the first airflow.

Various systems, methods, and devices are provided for focusing particles suspended within a moving fluid into one or more localized stream lines. The system can include a substrate and at least one channel provided on the substrate having an inlet and an outlet. The system can further include a fluid moving along the channel in a laminar flow having suspended particles and a pumping element driving the laminar flow of the fluid. The fluid, the channel, and the pumping element can be configured to cause inertial forces to act on the particles and to focus the particles into one or more stream lines.

An orifice pack is provided for delivering pressurized air to a compressor bleed valve of a gas turbine engine. The orifice pack has a diffusion chamber in serial flow communication with a tapering passage and a first outlet passage for venting a first portion of the pressurized air from the diffusion chamber. A second outlet passage branches off from the diffusion chamber at an axial location between the inlet and the tapering passage. The second outlet passage is fluidly connected to the compressor bleed valve for directing a second portion of the pressurized air from the diffusion chamber to the compressor bleed valve.

Disclosed is a system and method to separate solid particle components from a fluid. It can be used in close association with a hydrocarbon producing well and uses a novel combination of mechanical filtration, solids decantation, and real and apparent forces. Disclosed is a spherical vessel with a tangential inlet to introduce the fluid and a fluid exhaust and filter arranged on the center line of the interior of the vessel. A combination of pressurized fluid and solid particles enter at the tangential inlet and move primarily in a circular path around the interior of the vessel. The circular path results in the larger mass particles settling at the vessels lower region. Less massive particles may be entrained in the exiting fluid flow toward a filter element where they are removed from the exiting fluid. The vessel has an opening to remove the trapped separated particles.
