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: 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.

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 system for an engine includes a heat shield system and a crankcase ventilation system. The heat shield system includes at least one heat shield panel. The crankcase ventilation system includes at least one breather, at least one outlet, and at least one conduit extending from the at least one breather to the at least one outlet. A portion of the at least one conduit is coupled to the at least one heat shield panel to directly transfer heat from the heat shield system to the at least one conduit.
