Free-flow buoyancy check valve for controlling flow of temperature control fluid from an overflow bottle

A valve for controlling flow of temperature control fluid between a radiator fluid overflow container and a water pump in an internal combustion engine, the valve comprising:

• a housing in communication with the fluid overflow container and adapted to receive a flow of temperature control fluid therefrom, the housing having a valve chamber formed therein for channeling a flow of temperature control fluid, the housing also being in communication with the water pump and adapted to channel a flow of temperature control fluid between the valve chamber and the water pump,
• a cap attached to the valve housing and having a channel formed therein which is adapted to conduct fluid flow between the fluid overflow container and the valve chamber;
• a ball slidably disposed within the valve chamber and adapted to seal the channel in the cap to prevent fluid flow therethrough when the housing receives a flow of pressurized fluid from the water pump, the ball furthermore being adapted to seal the check valve outlet to prevent flow therethrough when the fluid overflow container has a low level of fluid contained therein;
• and
• a spring disposed between the ball and the cap for biasing the ball away from sealing the channel.

A system for controlling flow of temperature control fluid comprising:

• an fluid overflow container;
• a water pump;
• and
• a valve in communication with the fluid overflow container and the water pump and adapted to control flow of temperature control fluid between the fluid overflow container and the water pump, the valve includes a housing, and a chamber formed within the housing for conducting a flow of temperature control fluid between a cap and a check valve outlet, the cap being in communication with the fluid overflow container, and the check valve outlet being in communication with the water pump.

A system for controlling flow of temperature control fluid comprising:

• an fluid overflow container;
• a water pump;
• a valve in communication with the fluid overflow container and the water pump and adapted to control flow of temperature control fluid between the fluid overflow container and the water pump;
• and
• an air bleed tube disposed between and attached to the water pump and the fluid overflow container, the air bleed tube adapted to vent air from within the water pump.

A system for controlling flow of temperature control fluid comprising:

• an fluid overflow container;
• a water pump;
• and
• a solenoid valve in communication with the fluid overflow container and the water pump, the solenoid valve adapted to receive signals for controlling flow between the fluid overflow container and the water pump, the solenoid valve inhibiting flow of temperature control fluid into the fluid overflow container from the water pump, and preventing flow of air from the fluid overflow container to the water pump.
