An impactor separator comprises a housing having an inlet receiving a gas-liquid stream and an outlet expelling a gas stream. The impactor separator also includes an impaction surface positioned within the housing and configured to separate liquid particles from the gas-liquid stream and a nozzle assembly positioned within the housing. The nozzle assembly includes a nozzle assembly housing portion and a plurality of nozzles extending through the nozzle assembly housing portion. Each of the plurality of nozzles includes a nozzle inlet and a nozzle outlet. The gas-liquid stream enters into the nozzle assembly housing portion, flows into the plurality of nozzles through the nozzle inlet and exits the plurality of nozzles through the nozzle outlet. The plurality of nozzles accelerates the gas-liquid stream toward the impaction surface.

A fluid recovery system comprises a vapor recovery unit, control system, vent line, main vapor recovery unit inlet line, and a discharge line. The vapor recovery unit comprises a vapor recovery vessel and a vapor recovery compressor comprising a motor. The main vapor recovery unit inlet line is fluidly connected to the vapor recovery vessel. The vent line comprises a valve adapted to regulate packing case vapor flow through the vent line to the main vapor recovery unit inlet line. In certain embodiments the fluid recovery system comprises a gas scrubber tank, or a receiver tank, or gas-actuated control components. In certain embodiment, the system recovers vent gas, blow-by gas, or liquids or other fluids. In certain embodiment, the receiver tank receives fluids entrained in packing case vents and separates the fluid into liquids and vapor.

An oil separator includes a housing into which mixed gas in which unburned gas and engine oil are mixed with each other is introduced from a crank case; a centrifuge mounted in the housing and generating centrifugal force to the mixed gas to thereby separate the engine oil from the mixed gas; and a filter separator mounted in the housing and filtering the engine oil in the mixed gas. Since the engine oil is primarily separated through the centrifuge and secondarily separated through the filter separator, engine oil separation efficiency is improved as compared to the related art, and the same amount of gas may be treated even with a small size as compared to the related art.

A separator device for a system for recirculation of the blow-by gases of an internal combustion engine includes a casing containing a separation chamber and having an inlet for communication with the engine crankcase and an outlet for communication with the engine intake manifold, and drainage outlets ending in the engine crankcase, for returning the liquid separated in the separation chamber into the engine crankcase. Actuator means sensitive to pressure in the engine crankcase are associated to the inlet and to the drainage outlets so that when the pressure in the engine crankcase is higher than the pressure in the separator device, the inlet is open and the drainage outlets are closed, while when the pressure in the engine crankcase is lower than the pressure in the separator device, the inlet is closed and the drainage outlets are open.

A vibration-type oil separator includes a housing having a blow-by gas entering path through which a blow-by gas enters, an oil-discharging path which discharges an oil separated from the blow-by gas to outside, and a gas-discharging path which discharges a gas obtained by separating the oil from the blow-by gas to the outside. A vibration cylinder has an orifice formed thereon for escaping the gas and generating vibration by a back pressure of the blow-by gas and an external force applied to the housing to separate the oil and the blow-by gas. A fixing rod fixes the vibration cylinder in an internal space of the housing, in which both side portions thereof are fixed to the housing and a central portion thereof is fixed to the vibration cylinder.

An impactor separator comprises a housing having an inlet receiving a gas-liquid stream and an outlet expelling a gas stream. The impactor separator also includes an impaction surface positioned within the housing and configured to separate liquid particles from the gas-liquid stream and a nozzle assembly positioned within the housing. The nozzle assembly includes a nozzle assembly housing portion and a plurality of nozzles extending through the nozzle assembly housing portion. Each of the plurality of nozzles includes a nozzle inlet and a nozzle outlet. The gas-liquid stream enters into the nozzle assembly housing portion, flows into the plurality of nozzles through the nozzle inlet and exits the plurality of nozzles through the nozzle outlet. The plurality of nozzles accelerates the gas-liquid stream toward the impaction surface.

The impactor separator also includes an impaction surface positioned within the housing and configured to separate liquid particles from the gas-liquid stream and a nozzle assembly positioned within the housing. The nozzle assembly includes a nozzle assembly housing portion and a plurality of nozzles extending through the nozzle assembly housing portion. Each of the plurality of nozzles includes a nozzle inlet and a nozzle outlet. The gas-liquid stream enters into the nozzle assembly housing portion, flows into the plurality of nozzles through the nozzle inlet and exits the plurality of nozzles through the nozzle outlet. The plurality of nozzles accelerates the gas-liquid stream toward the impaction surface.

There is provided a breather chamber structure. An inner wall partitions a breather space surrounded by outer walls into a plurality of chambers including a first chamber, a second chamber, and a third chamber. An inlet allows the gas to flow into the first chamber. A first communication path communicates between the first chamber and the second chamber. A second communication path communicates between the second chamber and the third chamber. An outlet allows the gas in the third chamber to flow out of the breather space. An oil discharge port is configured to return oil separated from gas in the breather space to an oil reservoir. The third chamber has a volume equal to or greater than half of a volume of the breather space. The first chamber has a volume larger than a volume of any of the chambers except for the first and third chambers.

An oil separator includes a casing that has an inlet for air and an outlet for air, and an impingement member that is provided inside the casing. Air that contains oil is introduced through the inlet into the casing and caused to strike the impingement member so that the oil is separated from the introduced air and is recovered. The outlet opens in the horizontal direction of the casing. The oil separator further includes an L-shaped elbow member that is attached to the outlet. The elbow member protrudes in the horizontal direction from the outlet and is bent upward.
