WATER PRESSURE (FLOW RATE) STABILIZER Russian patent published in 1999 - IPC

FIELD: plumbing fittings; automatic stabilization of pressure (flow rate) after stabilizer, for example in pipe lines before water supply fittings. SUBSTANCE: instead of one rigid diaphragm with central orifice, use made of combined diaphragm consisting of one elastic diaphragm with central orifice and one rigid diaphragm with one central orifice and peripheral orifices covered by elastic diaphragm when pressure before diaphragms rises. Provision is made for dependence of sizes between orifices of diaphragms. EFFECT: enhanced reliability and efficiency; reduced losses of water during operation of fittings. 1 dwg
