A propulsion system for an aircraft includes a gas generating core engine that generates an exhaust gas flow that is expanded through a turbine section. A power turbine is forward of the core engine and is coupled to drive a propulsor. A hydrogen fuel syst...

A precleaner arrangement for separating a portion of entrained material from air flow air entering an engine air cleaner. The precleaner arrangement includes a precleaner housing and at least a first flexible air deflection vane with a fixed portion secure...

The invention relates to a valve plate device (VP), preferably for a device with fluctuating pressure conditions and/or fluctuating volume flows, in particular for a filter device (1) for a motor vehicle, wherein the valve plate device (VP) has at least tw...

The device has a filter element (7) arranged in a filter housing (2), where the filter element is designed as a multi-bellow filter with two radially inserted filter bellows (10, 11). One of the bellows is traversed by a fluid in a radial direction. A flow...

The filter has a prefractionator comprising an air outlet configuration that corresponds with a filter surface of a filter element (1). The prefractionator has a cyclone arrangement with individual cyclones (140) comprising a flow path (148). A receiver of...

The device has a housing (1) including an inflow area (61) separated from a fluid collection area (67) and a filter area by separation elements (39, 57). An exhaust connection (15) and other collection areas (36, 53) are connected to a clean side (33) of a...

A separator for removal of particulates from a fluid stream comprises a housing with inlet and outlet sections, a separator region, and a central hub to which are attached curved air foils shaped to catch the spiral clean flow from the cyclone separating r...

The cyclonic separator to separate particles from an air stream has a first stage with at least one centrifugal separator with a guide vane apparatus (12) to create a swirling movement of the fluid. The first stage is connected directly to a second stage w...

Cyclone (1) for separating foreign particles in a gas stream (2) comprises at least one rotating separating element (3) driven by a turbine wheel (4). Preferred Features: The separating element is a plate separator (5). The separating element and the turbi...

A vehicle air cleaner system 10 includes a cyclone chamber 14 and a variable inlet 30. The variable inlet 30 communicates airflow to the cyclone chamber 14 at a relatively constant velocity by varying an opening 32 in response to airflow which enters the i...
