ABSTRACT:
A regulator for evacuation systems including hospital aspiration systems, such regulator being inexpensively manufactured and assembled and providing a number of unique features. The subject regulator is designed to be essentially independent of altitude of operation or humidity conditions, may be made discretely or continuously variable, and also is provided with features reducing, if not eliminating, any noise of air drawn into the system for regulation purposes. An important feature of the invention is the provision of one or more metering apertures of reduced cross section such that possible error of observable knob setting is reduced to an absolute minumum, thus eliminating the necessity of mechanical-adjustment calibration. Settings are essentially accurate for all altitudes, humidity conditions, and particular pumping parameters of existing vacuum systems. The particular metering apertures, above referenced, are serially related to a unique, slotted airway metering pattern designed to give wide versatility through extended permissible settings. Full-vacuum, and shut-off structural features are also provided.
