Estimating the term…
A device for treating and conditioning engine coolant for use with an internal combustion engine includes a housing having an inlet and outlet and a filtering media and container carrying coolant treatment material located within the housing. Coolant passes through the filter, and then is exposed to the tip of a rod which erodes away to permit treatment material to be discharged in the coolant. As the corrosiveness of the coolant decreases, erosion of the rod is discontinued, so that additional treatment material is no longer discharged into the coolant. Accordingly, the corrosiveness of the coolant is controlled to within relatively narrow limits.
Device for treating and conditioning engine coolant comprising a housing having an inlet and an outlet, means within said housing for defining a flow path for said coolant between the inlet and the outlet, a container within said housing for storing a quantity of coolant treatment material, valve means for controlling the discharge of said coolant treatment material from said container into said flow path, and corrosiveness responsive means responsive to the corrosiveness of the coolant for discharging said coolant treatment material through said valve means when the corrosiveness of the coolant attains a predetermined level and thereafter permitting said valve means to reclose.
