Abstract
A cooling system closure includes a closure apparatus adapted to mount on a cooling system and formed to include a flow passage arranged to receive fluid discharged from the cooling system and a relief valve positioned to move between an opened position permitting fluid to flow through the flow passage and a closed position blocking the flow of fluid through the flow passage. The relief valve includes a temperature-activated element moving to a first position when heated to a first predetermined temperature to urge the relief valve to the closed position and a second position when cooled below a second predetermined temperature to permit the relief valve to move to the opened position.
Claims52
A cooling system closure comprising
- a closure apparatus adapted to mount on a cooling system and formed to include a flow passage arranged to receive fluid discharged from the cooling system and
- a relief valve positioned to move between an opened position permitting fluid to flow through the flow passage and a closed position blocking the flow of fluid through the flow passage, the relief valve including a temperature-activated element moving to a first position when heated to a first predetermined temperature to urge the relief valve to the closed position and a second position when cooled below a second predetermined temperature to permit the relief valve to move to the opened position.
A cooling system closure comprising
- a closure apparatus adapted to close a cooling system and defining a flow passage arranged to communicate fluid discharged from the cooling system and
- means for controlling the flow of fluid through the flow passage, the controlling means being temperature activated to move from an opened position permitting the flow of fluid through the flow passage when the temperature extant in the cooling system is below a first predetermined temperature level and a closed position blocking the flow of fluid through the flow passage when the temperature extant in the cooling system is above a second predetermined temperature level.
A cooling system closure comprising
- a closure apparatus configured to couple to a cooling system and configured to receive fluid discharged from the cooling system and
- a relief valve positioned to move between an opened position permitting the flow of fluid through the closure apparatus and a closed position blocking the flow of fluid through the closure apparatus, the relief valve including a temperature-activated element moving between an activated position when the temperature extant in the cooling system is above a first predetermined temperature and a deactivated position when the temperature extant in the cooling system is below a second predetermined temperature, the temperature-activated element being positioned to urge the relief valve to the closed position when in the activated position.
A cooling system closure comprising
- a closure apparatus adapted to seal a cooling system and formed to include a flow passage arranged to receive fluid discharged from the cooling system,
- a valve member positioned to move between an opened position permitting fluid to flow through the flow passage and a closed position blocking the flow of fluid through the flow passage, and
- a temperature-activated spring moving to an activated position when heated to a first predetermined temperature to urge the valve member to the closed position and a deactivated position when cooled below a second predetermined temperature to permit the valve member to move to the opened position.
A cooling system closure comprising
- a closure apparatus adapted to seal a cooling system and formed to include a flow passage arranged to receive fluid discharged from the cooling system,
- a valve member positioned to move between an opened position permitting fluid to flow through the flow passage and a closed position blocking the flow of fluid through the flow passage,
- a spring, and
- a temperature-activated element moving to an activated position when heated to a first predetermined temperature to compress the spring and urge the valve member to the closed position and a deactivated position when cooled below a second predetermined position to decompress the spring and move the valve member to the opened position.
A cooling system closure comprising
- a closure apparatus adapted to seal a cooling system and formed to include a flow passage arranged to receive fluid discharged from the cooling system and
- a temperature-activated valve member positioned to move between an opened position permitting fluid to flow through the flow passage and a closed position blocking the flow of fluid through the flow passage, the temperature-activated valve member moving to the closed position when heated to a first predetermined temperature and the opened position when cooled below a second predetermined temperature.
