Abstract
178,162. Fisher, S. Dec. 8, 1920. Addition to 155,417. Pressure gauges, applications of; with signal and alarm arrangements. -In the pressure gauge device for indicating faulty compression or ignition described in the parent Specification, the piston D connected directly to the indicator H is loosely mounted in the cylinder B and a non-return valve G is interposed between the piston and the combusticn space of the engine. During normal firing, the valve G opens, the piston D is forced up, and the highest indication given and maintained. If ignition does not take place, the gases leak past the piston B until the pressure is equalized, and the indication corresponds to the highest compression in the cylinder. If the compression is faulty, the valve G remains closed, the spring F becomes fully expanded and the indicator assumes the third position. The spring K anchoring the indicator may be above or below it, and the indications may be shown on a drum or disc.
