  • Internal combustion engine fluid-metering valve assembly
    Patent number: 9695734
    Abstract: A fluid-metering valve assembly for use in a coolant regulator of an internal combustion engine cooling system may include a main body and a metering member. The main body is configured to be rotatably secured within an internal chamber of the coolant regulator. A fluid passage is formed through the main body, and is defined, at least in part, by a metering edge of the main body. The metering member is formed proximate to the metering edge of the main body, and is configured to allow variable doses of fluid to be metered into or out of the coolant regulator as the main body is rotated within the coolant regulator. The metering member includes one or more linear features formed into the main body.
