Abstract

1360675 Cooling IC engine valve cages; stopping engines MASCHINENFABRIK AUGSBURG-NURNBERG AG 3 Sept 1971 [8 Sept 1970] 41298/71 Headings F1B and F1K [Also in Division F2] The liquid-coolant inlet and outlet conduits 9 and 10 of an exhaust valve cage which is removable from the cylinder head of a liquidcooled engine without removing the head are provided with a valve 2 or respective valves for shutting off coolant flow therethrough. The fusto-conical or cylindrical rotatable valve 2 has inlet and outlet chambers 6 and 7 with apertures 8 and 11 movable into and out of register with the conduits 9 and 10. A by-pass conduit 19 may be provided between the chambers 6 and 7 or between the cylinder head coolant passages upstream of the valve 2 and a conduit downstream of the valve 3. The conduit 19 may have a high flow resistance relative to the conduits 9 and 10 if open when the valve 2 is either open or closed or a small flow resistance if open only when the valve is closed. A static pressure responsive switch 17 may be connected by a conduit 16 and a valve aperture 15 to the coolant supply when the valve 2 is closed. The switch 17 operates a visual or audible alarm when the engine is running and the valve is closed. A nozzle 18 in the conduit 16 provides for relief of pressure in the conduit. A dynamic pressure responsive switch 22 may be provided in the conduit 19 or a switch responsive to static pressure may be provided on a blind branch from the conduit. The switches 17 or 22 may act on the control of the engine fuel pumps through a time delay relay to prevent fuel delivery and stop the engine after engine starting with the valve 2 closed. The inlet and outlet conduits of a plurality of exhaust valve cages may have a single shut-off valve.
