Abstract
A filter device for an engine coolant includes a housing with an inlet for inflow of coolant and an outlet air outflow; a flow path extends between the inlet and outlet, a filter in the flow path filters the coolant; a dosage of corrosion inhibitor is disposed in the housing, corrosion inhibitor being separated from the flow path by a separating means exposed to coolant in the flow path; the separating means disintegrates by corrosion when coolant in the flow path has a corrosiveness above a predetermined level thereby releasing the dosage of corrosion inhibitor into the coolant.
Claims6
A container for the addition of corrosion inhibitor to the cooling system of an engine, comprising:
- a container member having a closed end and a tubular wall with a metallic inner surface;
- a partition member and extending between opposed sides of said tubular wall spaced from said closed end to define a compartment for a dosage of corrosion inhibitor material, the partition member having a peripheral edge portion being formed of metallic material anodic to the tubular wall inner surface;
- and the tubular wall being compressed into tight engagement with the partition member forming a fluid tight galvanic couple therebetween.
