Radiator pressure release valve for a temperature control system

摘要

A radiator pressure relief valve is disclosed for transferring fluid from a radiator to an overflow bottle to relieve pressure in the radiator. The valve includes a housing with an internal chamber and an inlet and outlet communicating with the chamber. A valve member is located within the housing adjacent to the inlet. The valve member is movable with respect to the inlet and adapted to prevent fluid flow from the inlet into the chamber when the valve member is positioned against the inlet. A support pin is located within the housing and movable with respect to the valve member. The support pin has a first position where the support pin is in contact with the valve member and inhibits movement of the valve member and a second position where the support pin is spaced apart from the valve member. A spring is mounted within the housing and biases the valve member away from the support pin.
