Abstract
A pressure sensor includes a pressure sensing element in fluid communication with a port and an oil separator in the port. The oil separator is configured to reduce an amount of oil-vapor residue that reaches the pressure sensing element by elongating a path of fluid from an opening of the port to the pressure sensing element and by creating additional surface area within the port upon which oil-vapor residue may be deposited. There is also a cover, which has holes, and that is configured to prevent the oil separator from falling out of the port. The oil separator may include circular discs having cut-out portions. The cut-out portions on adjacent circular discs may be rotated relative to one another about a longitudinal axis of the oil separator. The cut-out portions may have a semi-circular shape.
