ABSTRACT:
The valving element is positively tied to a pressure-sensing and -responsive diaphragm, via a diaphragm-carried insert. The connection is so arranged as to permit relative angular displacement, between the valving element and the diaphragm, so that cocking of the element, in its axial movement, will not occur. The gas filter is formed of a sintered plastic to avoid corrosion and flaking off of metallic particles. An aspirator hole communicates the diaphragm with the low-pressure chamber outlet, but has an artificially lower pressure, than the outlet pressure, introduced to the diaphragm, through the use of an ejector nozzle. A hole formed in the bonnet establishes atmospheric pressure above the diaphragm, but a porous plug in the hole prevents any ingestion of water, from puddle-splashing, take up from wet roads, and the like.
