摘要

"IMPROVEMENTS IN PRESSURE AND FLOW REGULATION DEVICES, FOR DIRECTLY REFRIGERATED WATER BRIDGES", characterized by the fact that to regulate the displacement of the mobile interior part, which opens and closes the chilled water passage valve, it has been provided, coaxially with the stem emerging from said piece, an adjustable part, from which a washer protruding limiting the downward stroke of the moving part, when pushed by the manual pressure, exerted on the pulsator of the device, being transmitted said pressure by means of a screw, to a spring disposed on the adjustable piece, said assembly being guided, in its slight upward and downward movements, by virtue of an internally threaded sleeve in which the said screw is screwed to regulate the pressure of the said spring, said inner sleeve sliding by the cylindrical passage established in the cover of the inner box of the regulating device of the pressure of chilled water.
