Patent ID: 8840380

Claim:
A device for the temperature control of an air pump, the pump having a housing top and a housing bottom, the housing top defining a pumping chamber having an impeller, the device in fluid communication with a supply of liquid heated by an engine, the housing bottom having an annular lip which defines an outer diameter of the annular lip, the device comprising: a ring having a top surface, a bottom surface, a fluid inlet, a fluid outlet, and an inner passage, the fluid inlet and the fluid outlet spaced apart being coplanar with and defined by the inner passage top surface and bottom surface, the inner passage extending between the fluid inlet and the fluid outlet, the ring defines an outer diameter of the ring, the outer diameter of the annular lip is substantially similar to the outer diameter of the ring; an annular wall disposed on the housing top; an upper surface disposed on the housing bottom, the annular wall of the housing top spaced apart from the upper surface of the housing bottom, the upper surface of the housing bottom abutting the bottom surface of the ring, the annular wall of the housing top abutting the top surface of the ring; the fluid inlet, the fluid outlet, and inner passage being in fluid communication with the liquid heated by the engine; wherein the top surface of the ring transfers heat energy to and from the housing top and the bottom surface of the ring can transfer heat energy to and from the housing bottom when the ring is disposed between, and in mechanical communication with, the housing top and the housing bottom to prevent ice dams from forming in the pump.
