A thermostatic valve assembly for an internal combustion engine cooling system. The thermostatic valve assembly including a valve housing and a plunger assembly. The valve housing includes a chamber, an inlet port, a radiator output port, and a bypass output port. The bypass output port including a flow opening. The plunger assembly being slideably secured within the chamber and moving between a first position to close the flow opening and a second position to open the flow opening. The plunger assembly comprises a body and at least one seal configured to seal the flow opening when in the first position.

A deaeration valve includes a housing and a ball in fluid communication with housing. The ball can include a body, a seat defining a bleed passage therein, and a deaeration pin slidably disposed within the bleed passage. Further, the deaeration pin may include a head, a retention feature, and a shaft positioned between the head and the retention feature.

Deaeration valve

A four-way hall valve includes a linear gear for operating the ball element in the valve and a temperature responsive wax element connected to the linear gear for moving the linear gear and rotating the ball in response to temperature change.

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.

A pressure responsive regulator valve particularly suitable for a vehicle fuel system includes a substantially monolithic T-shaped body having a first bore defining a substantially unrestricted fluid flow path therethrough and a second bore in fluid flow communication with the first bore. A pressure responsive valve is provided in the second bore to open and close a fluid flow path through the second bore.
