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: 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: 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.

Abstract: The present disclosure relates to a fluid supply system for a machine. The fluid supply system includes a throttle assembly having a first shaft attached to a valve member and a fluid shutoff assembly. The fluid shutoff assembly includes a second shaft, a locking member having an axis parallel to an axis of the second shaft and comprising a locking arm extending toward the second shaft, a biasing member fixedly attached to the second shaft, a releasing mechanism adjacent to the locking member that rotates the locking member about the longitudinal axis of the locking member, and a coupler comprising a first coupling hub attached to the first shaft and a second coupling hub attached to the second shaft and interfaced with the first coupling hub.

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: An internal combustion engine includes a crankcase having first and second pluralities of openings. A oil separation module has at least one inlet housing that communicates with a oil separation filter and is connectable to at least one opening from the first plurality of openings or from the second plurality of openings to define a crankcase vent.

Abstract: A conduit for transferring fluid from one location to another. The conduit includes a tube having an outer surface and an insulation layer surrounding the tube. A heating layer is disposed between the insulation layer and the tube, such that the heating layer is wrapped around the outer surface of the tube. The conduit includes a reinforcement layer sandwiched between the insulation layer and the heating layer.
