Abstract: An air shutoff valve for use on an internal combustion engine includes a gate that is moveable between armed and triggered positions by springs when a release pin is retracted and allows a spring loaded retention pin to retract and release the gate, which is also spring loaded, to drop. The release pin is operated by an actuator.

Abstract: Apparatuses, systems and methods are disclosed including apparatus for separating oil from a blow-by gas of an engine. The apparatus can include an outer housing, an inner housing, a filter, one or more ports, a first cover and a second cover. The inner housing can be positioned within the outer housing and defines an inner cavity. The inner housing and the outer housing can form a jacket therebetween. The filter configured to separate the oil from the blow-by gas positioned within the inner cavity. The one or more ports can be configured for fluid communication with the jacket. The first cover can have at least a first port therein to receive the blow-by gas or allow the blow-by gas to pass from the first cover. The second cover can have a second port therein to receive the blow-by gas or allow the blow-by gas to pass from the second cover.

Abstract: Apparatuses, systems and methods are disclosed for separating oil from a blow-by gas of an engine. An example includes engine system includes a crankcase having a blow-by gas passing therethrough, a compressor configured to receive air and compress the air, an aftercooler, an oil separating apparatus and a jet pump. The aftercooler communicates with the compressor and is configured to cool at least a portion of the air compressed by the compressor. The oil separating apparatus communicates with the blow-by gas. The oil separating apparatus communicates with a boost air that is a mixture of the compressed air from the compressor and cooled air from the aftercooler. The jet pump communicates with both the blow-by gas after leaving the oil separating apparatus and the boost air after leaving the oil separating apparatus and is configured to combine the blow-by gas and the boost air.

Abstract: Apparatuses, systems and methods are disclosed for separating oil from a blow-by gas of an engine. An example includes a method that includes passing the blow-by gas to a first oil separating apparatus and a second oil separating apparatus, wherein the first oil separating apparatus and the second oil separating apparatus are physically coupled together along interfacing surfaces and in fluid communication with one another as an array, separating the blow-by gas by passing the blow-by gas through respective filters of the first oil separating apparatus and the second oil separating apparatus, removing the oil from the blow-by gas with the respective filters and recombining the blow-by gas after passing from the respective filters; passing the blow-by gas as a single flow stream from the first oil separating apparatus and the second oil separating apparatus.

Abstract: An engine system optionally including: a crankcase of an engine having a blow-by gas passing therethrough; a liquid source containing a liquid; and an oil separating apparatus in fluid communication with the blow-by gas. The oil separating apparatus having a coalescing filter to separate oil from the blow-by gas. Separate from the blow-by gas and the coalescing filter, the oil separating apparatus is in fluid communication with the liquid source to receive the liquid. The liquid is passed through the oil separating apparatus in a heat exchange relationship with the blow-by gas to maintain a desired temperature range for the blow-by gas.

Abstract: A valve system may include a valve having a housing with a bore and a valve member positioned within the bore. The valve member may include a valve shaft with a recess. The valve system may also include an actuator having an actuator shaft with an end portion. An adapter may couple the valve shaft and the actuator shaft. The adapter may include a body having a shape corresponding to a shape of the recess of the valve shaft for fitting the adapter within the recess and an aperture extending into the body. The aperture may have a shape corresponding to a shape of the end portion of the actuator shaft for press fitting the adapter onto the actuator shaft. The adapter may fit within the recess and press fit coupled to the actuator shaft.
