A hand vacuum cleaner comprises a cyclone, a conical pre-motor filter that is positioned rearward of the cyclone and a suction motor. The pre-motor filter has a front end that faces towards the cyclone air outlet. The conical pre-motor filter has an open interior volume, an outer surface, which is an upstream surface of the pre-motor filter, and an inner surface, which is a downstream surface of the pre-motor filter.

A centrifugal separation type oil separator includes an oil separator body having a cylindrical body portion, and a bent pipe provided on an outer peripheral side of the body portion to surround the body portion in a circumferential direction, to introduce a fluid containing an oil into the oil separator body. The bent pipe includes an outer wall portion extending in the circumferential direction of the body portion and expanding radially outward from the body portion, and an inner wall portion extending along the outer wall portion and blocking an open part of the outer wall portion. The outer wall portion and the inner wall portion are formed by different members. An upper side of the body portion is open. The oil separator body has an upper cover blocking an open portion of the body portion. The inner wall portion and the upper cover are formed by an integral member.

An oil separator includes a cover attached to an opening portion on a discharge side of a compressor, a discharge flow path formed in an inside of the cover, and an oil separation portion configured to separate an oil from a fluid that has flowed out from the discharge flow path. A dividing wall portion partitions an internal space facing the opening portion into a plurality of spaces. The dividing wall portion is provided in the inside of the cover. The internal space is a discharge space into which a high-pressure gas refrigerant discharged from the compressor flows. Each of the plurality of spaces faces a high-pressure chamber in the opening portion so as to be in direct communication with the high-pressure chamber.

A device for filtering a flow of cooling air for cooling a low-pressure turbine of a turbomachine, includes a duct having a geometry configured to centrifuge the flow of cooling air passing through the duct, the duct having openings dimensioned to enable a separation of the solid particles contained in the flow of cooling air being centrifuged.

Disclosed herein are phase separator devices, and related methods of fabrication and use. The disclosure provides improved phase separator devices for phase separation of input feeds, and systems/methods for utilizing and fabricating the devices. The disclosure provides phase separator devices utilizing inertial separation and porous media extraction for the phase separation of two-phase input feeds (e.g., to separate an input feed of a two-phase mixture to a first phase output (e.g., to a liquid output flow) and to a second phase output (e.g., to a gas output flow)). The device can separate a mixed fluid flow of both liquid and gases. The liquid and gas can include liquid and vapor phases of the same chemical/constituent (e.g., ammonia), or may include liquid and gases of two different constituents (e.g., liquid water and air). The phase separator devices can be utilized at standard gravity to micro-gravity to zero gravity environments.
