Abstract: A fluid supply system for a machine such as an internal combustion engine includes a shutoff valve having an electrical actuator that includes a solenoid subassembly, and a stabilizer for the electrical valve actuator. The stabilizer includes a fitting structured to couple the shutoff valve to adjacent hardware in the fluid supply system, and a strongarm extending between the fitting and the solenoid assembly and clamped to the solenoid subassembly. A vibration-damping reinforced grommet may be clamped between the solenoid subassembly and the clamp.

Abstract: Apparatuses, systems and methods are disclosed including apparatus for a ventilation system for supplying air to a crankcase of an internal combustion engine. The apparatus can optionally include a housing, an air filter, a lid and a pressure relief valve. The housing can form a cavity and having an inlet and an outlet therein. The inlet communicates with the cavity and is offset from a centerline axis of the housing. The air filter can be received by the cavity. An outer circumference of the air filter can be oriented at an angle that is substantially tangent to the inlet. The lid can be attachable to and removable from the housing for selectively accessing the air filter. The pressure relief valve coupled to the housing and in fluid communication with the cavity.

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.
