Abstract: A positive crankcase ventilation valve assembly including a housing having a fluid inlet and outlet. A poppet valve is arranged in the housing between the fluid inlet and outlet and is movable in a axial direction between a plurality of positions. The positions respectively define a plurality of fluid flow rates. A plurality of ribs extend radially from either the poppet valve and the housing in an axial direction. The ribs define a bearing surface between the housing and the poppet valve. In this manner, the poppet valve is supported within the housing with a reduced bearing surface area while aligning the poppet valve relative to the housing throughout its movement between the positions. In another embodiment, the poppet valve is eliminated to prevent problems associated with an improperly operating poppet valve. A diaphragm is arranged in the housing between the fluid inlet and outlet.

Abstract: A rotor assembly for an electric motor includes a drive assembly, a cup that receives a portion of the drive assembly, and a magnet core assembly received between the drive assembly and the cup. The magnet core assembly is hermetically sealed between the drive assembly and the cup.

Abstract: A PCV valve assembly includes a housing that is defined by a first housing section and a second housing section. A poppet valve is supported within the housing. The first housing section includes a threaded end that defines a fluid inlet, and the second housing section includes a cylindrical outlet stem and an end flange that defines a restricted integral orifice as a fluid outlet. The diameter of the orifice is smaller than the diameter of the cylindrical outlet stem. A fluid chamber between the end flange and the poppet valve averages out variations in the fluid flow through the PCV valve assembly, thereby reducing vacuum pulsation.

Abstract: A PCV valve assembly including housing having a fluid inlet and outlet. A poppet valve is disposed in the housing between the fluid inlet and outlet and is moveable in an axial direction between a plurality of positions. A heating element having a positive temperature coefficient material is supported in the housing in proximity to at least a portion of the valve for automatically heating the valve in response to a given voltage. The material produces a first heat in response to a first temperature and the given voltage. The material produces a second heat less than the first heat produced in response to the given voltage and a second temperature greater than the first temperature. That is, the positive temperature coefficient material automatically regulates the flow of current and the temperature produced without the need of a thermostat in response to the same voltage.
