ABSTRACT:
A thermostat for controlling the flow of coolant in an automotive cooling system comprises a centrally apertured disc forming a valve seat; a saddle member supported on the disc and straddling the aperture; a valve member positioned between the saddle and the disc; a spring biasing the valve member into engagement with the seat; a thermally responsive element for opening the valve against the spring in response to a predetermined temperature rise of the coolant; and a plurality of tabs formed in the disc and concentrically surrounding the valve seat adapted to rupture and deflect in response to a predetermined system pressure rise to form fluid passages bypassing the valve, the tabs being defined by score or cut lines extending partly around each tab.
