A separator for separating liquid from a gas flow is provided with a nozzle carrier element provided with a nozzle arrangement having one or more nozzles. An impact element is arranged downstream in flow direction of the gas flow at least partially opposite the nozzle arrangement. A permanent cover device is provided that covers at least one of the one or more nozzles of the nozzle arrangement. The permanent cover device reduces by at least 50% a through-flow of the gas flow through the at least one of the one or more nozzles of the nozzle arrangement compared to the one or more nozzles of the nozzle arrangement that are free from the permanent cover device. An assembly kit for producing such a separator is provided with a nozzle carrier element with nozzle arrangement and one or more nozzles, an impact element, a cover device, and a liquid reservoir.

The invention relates to an internal combustion engine, comprising an intake path, a crankcase, an exhaust gas path and a crankcase ventilation means, wherein the crankcase ventilation means is open, closed or separate. The internal combustion engine according to the invention comprises an intake path, a crankcase, an exhaust gas path and an open crankcase ventilation means, wherein the open crankcase ventilation means comprises a first line and a second line, wherein the first line is designed to connect the exhaust gas path to the crankcase in order to guide exhaust gas out of the exhaust gas path to the crankcase, and wherein the second line is designed to connect the crankcase to the exhaust gas path in order to discharge exhaust gas and leakage gases located in the crankcase from the crankcase and to feed them to the exhaust gas path.

A high throughput, positive pressure, gravity operated dewatering system for hydraulic fluids, lubricating fluids, and petroleum based fluids comprises a gravity operated dewatering chamber receiving the industrial fluid and a source of positive pressure drying air coupled to the dewatering chamber.

A separator for a separator device, for example a final separator for a final separator device for separating water from a liquid such as oil and/or fuel, may include a filter body including at least one filter material through which the liquid can flow. The filter body may have a first side and a second side. A nanofibre layer may be disposed on the first side in at least one region. The nanofibre layer may be configured hydrophobic. According to an implementation, the nanofibre layer is treated to produce the hydrophobic property. The filter body may have a porosity on the first side that is smaller than on the second side.

This blow-by gas system is provided with: a blow-by gas flow path through which a blow-by gas discharged from an internal combustion engine passes; and an oil separator disposed midway along the blow-by gas flow path. A downstream end of the blow-by gas flow path connects to at least one of a predetermined portion of an intake passageway and a midway portion of an air introduction passageway. The predetermined portion is a portion at which at least some of the blow-by gas that has flowed into the intake passageway flows into the air introduction passageway together with an intake air in the intake passageway.

An internal combustion engine includes a crankcase and a cylinder head. The cylinder head and the crankcase delimit at least one cylinder in which a translationally moving piston is arranged. A water injection device injects water into the at least one cylinder. A crankcase ventilation device is fluidically connected to the crankcase. A blow-by mixture containing injection water can flow through the crankcase ventilation device. The crankcase ventilation device has an activated charcoal filter. The blow-by mixture containing the injection water can flow through the activated charcoal filter.

A breather device and a snow removal machine having the breather device have a casing into which blowby gas of an engine flows, an air suction port for letting out gas from the inside of the casing, and a gas-liquid separation mechanism for separating moisture contained in the blowby gas. The gas-liquid separation mechanism separates an inlet, which allows the blowby gas to flow in, and the air suction port by a predetermined distance, and has the air suction port positioned above a liquid path through which the moisture flows. A gas path allows the blowby gas to flow from the inlet to the air suction port without passing through an air cleaner element.

This blow-by gas system is provided with: a blow-by gas flow path through which a blow-by gas discharged from an internal combustion engine passes; and an oil separator disposed midway along the blow-by gas flow path.
