A dry material transfer pump comprises an outer tube including an outer tube channel having an upstream end that is axially aligned with a downstream end thereof, and a plenum portion having a cross-sectional width that is larger than a cross-sectional width of the outer tube channel. A pressurized gas inlet is defined through the outer tube and is in fluid communication with the plenum portion. An inner tube is disposed annularly within the outer tube channel and defines an inner tube channel configured to receive particulate matter. At least one opening is defined radially through a wall of the inner tube and fluidly couples the plenum portion to the inner tube channel to allow the pressurized gas to flow from the plenum portion into the inner tube channel and create suction within the inner tube channel for drawing the particulate matter through the inner tube channel.

A gas-liquid separator comprises a housing comprising a first inlet structured to receive a blowby gas stream, the blowby gas stream having a first flow velocity, and a second inlet structured to a communicate a compressed gas into the housing, at least a portion of the second inlet disposed within the first inlet. An elastomeric nozzle is coupled to the first inlet and positioned around the second inlet, the elastomeric nozzle structured to combine the blowby gas stream with the compressed gas such that the compressed gas causes the blowby gas stream to flow at a second flow velocity that is greater than the first flow velocity. An impaction plate is disposed downstream of the elastomeric nozzle such that the blowby gas stream impacts the impaction plate and separates liquid and aerosol contained in the blowby gas stream.

Various example embodiments relate to an automatic drain system for use with a fluid water separator. The automatic drain system includes a liquid-in-fuel sensor. The liquid in-fuel sensor is configured to detect a liquid level in a water sump. The solenoid has an open state and a closed state. A control unit is configured to activate the solenoid in response to a signal from the liquid-in-fuel sensor. Activation of the solenoid causes the solenoid to go from the closed state to the open state. The automatic drain system is placed in a condition for allowing fluid flow through the automatic drain system from the water sump.

Gas/liquid coalescing filter auto drain

A filter apparatus is described that has a torque limiting device, which may be a clutch mechanism, and which provides a protective function for a filter, so as to protect a filter from being over tightened and to thereby prevent damage to filter components. The clutch mechanism can also eliminate or reduce the need for torque measurement of certain filter components. The clutch mechanism can be located on one of the fluid filter, a filter head which engages the fluid filter, or a combination of both the fluid filter and the filter head.

An internal combustion engine crankcase ventilation rotating coalescer includes an annular rotating coalescing filter element, an inlet port supplying blowby gas from the crankcase to the hollow interior of the annular rotating coalescing filter element, and an outlet port delivering cleaned separated air from the exterior of the rotating element. The direction of blowby gas is inside-out, radially outwardly from the hollow interior to the exterior.

An inertial gas-liquid impactor separator and method is provided, including multiple stages and multiple variable flow controllers.
