Gasdruckregelventil mit geradem Durchgang

摘要

In a gas pressure regulating valve provided with a straight passage for the gas and having therein a stationary valve member and a pressure-actuated axially slidable valve sleeve, one end of which cooperates with said stationary valve member, the valve sleeve in accordance with the invention is provided between its ends with an annular shoulder subjected to a pressure medium which adjusts the position of the valve sleeve in said passage. This valve sleeve may be reversely inserted in said straight passage so that the valve sleeve may be moved by said pressure medium which adjusts said valve sleeve in a closure or opening direction.
