Abstract

Регулируем редуцирвентил, включващ пружинно бутало, което разделя изходящия и входящия отвор, и регулиращ клапан, характеризиращ се с това, че регулиращият клапан е оформен като диференциално бутало или като пружинна тарелка, чиито големи и малки напречни плоскости са съединени както помежду си , така и с входящия отвор, директно или чрез дроселиращ отвор, като разстоянието между разликата от повърхността на голямата и малката напречна плоскост е съединено с изходящия отвор. Патентните претенции са формулирани в 1 точка.An adjustable reducing valve comprising a spring-loaded piston that separates the outlet and inlet ports and a control valve, characterized in that the control valve is shaped as a differential piston or a spring plate, the large and small transverse plates of which are connected both to each other and with the inlet port, either directly or through a throttling port, the distance between the difference from the surface of the large and small transverse planes being connected to the outlet port. The patent claims are formulated in 1 point.
