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.

A negative pressure-side flow path having a negative pressure-side filter and a positive pressure-side flow path having a positive pressure-side filter are connected in parallel between a first port and a second port, and a shuttle valve is installed between the negative pressure-side flow path and the positive pressure-side flow path, and the first port, thus when a negative pressure is supplied to the first port, the first port is caused to communicate with the second port through the negative pressure-side flow path, and when a positive pressure is supplied to the first port, the first port is caused to communicate with the second port through the positive pressure-side flow path.

A gas-liquid separator and method and air compressor system. The gas-liquid separator includes a separator tank having wet side and dry side chambers. The wet side chamber separates and collects liquids from pressurized air that enters through a tank inlet. A separation valve inlet port connects the wet side chamber with the dry side chamber and allows moist air to pass from the wet side chamber to the dry side chamber and prevents collected liquids from passing from the wet side chamber to the dry side chamber. A separation valve assembly opens the separation valve inlet port when pressurized air is forced into the wet side chamber and a pressure is met and/or exceeded and to close the separation valve inlet port when pressurized air is not being forced into the wet side chamber and pressure falls below the pressure.

A fluid cleaning and filtering system includes a pre-treatment system before a force generation turbine to condense and pretreat gases and particulate matter; a flow rectifier before a tangential inlet; diffuser pipes for compressing the gases and particulate matter therein and project same into the deflector disks, diffuser pipes at an outlet of the so-called condenser, a purger, a diffuser and a deflector; a force generation turbine; an energy generator using torque from the turbine rotor; an internal energy generator; a flow rectifier in a first tangential inlet and a flow rectifier in a second tangential inlet; a new full-cone atomizer nozzle to wet particles and clean gases; a diffuser in the condensers and a deflector disk for the condensers.

A cyclone separation device includes a cyclone chamber for separating dirt from incoming air, a dirt collecting chamber arranged adjacent to the cyclone chamber for collecting dirt particles separated from air, and a dirt duct between the cyclone chamber and the dirt collecting chamber for allowing dirt particles to exit the cyclone chamber into the dirt collecting chamber. To reduce the generation of noise-generating air vortices, the dirt duct has an edge protruding into a direction at an angle to the dirt duct at an exit ridge of the cyclone chamber that is first encountered by the air rotating in the cyclone chamber. Preferably, the edge is formed by a tangential extension of a wall of the cyclone chamber. A vacuum cleaner advantageously includes such a cyclone separation device.

Systems and methods are described for introducing an impingement gas and an enhancement gas to an aerosolized sample within a spray chamber. A system embodiment includes, but is not limited to, a chamber body; an input port coupled to the chamber body, the input port configured to receive an aerosolized sample and direct the aerosolized sample into the chamber body; an exit port coupled to the chamber body, the exit port configured to receive at least a portion of the aerosolized sample from the chamber body; an impingement gas port coupled to the exit port and configured to introduce an impingement gas to the at least a portion of the aerosolized sample; and an enhancement gas port coupled to the exit port configured to introduce an enhancement gas to the exit port.

A cyclonic separating apparatus comprising a first cyclonic separating unit and, downstream from the first cyclonic separating unit, a second cyclonic separating unit comprising a plurality of cyclones arranged fluidly in parallel about a first axis and a dust collector arranged to receive dust from each of the plurality of cyclones. Each of the plurality of cyclones in the second cyclonic separation unit comprise a fluid inlet and a fluid outlet, the plurality of cyclones being divided into at least a first set of cyclones and a second set of cyclones, the fluid inlets of the first set of cyclones arranged in a first group and the fluid inlets of the second set of cyclones arranged in a second group spaced along said axis from the first group. Each outlet of the plurality of cyclones in the second cyclonic separation unit is provided by a common plate-like vortex finder member.

The present disclosure provides methods and apparati for separating liquids from production gases and recovering the liquids. The methods and apparati of the present disclosure can reduce or eliminate emissions compared to standard methods and devices and also eliminate the need for haul away of liquids by collecting compressor system liquids in charge vessel(s). The methods and apparati of the present disclosure can also be used to fuel the engines which operate the compressor systems using gas from the compressor drains and the gas used to drain the charge vessel(s).
