Pressure regulator for liquid or gaseous media »

The invention relates to a device that can be kept in distribution networks Pressure regulator for liquid and gaseous media, which has a body consisting of two halves, between which a membrane separating the two halves of the body is provided, which provides a Kainrer-for the passage of the medium is limited or defined.

All disadvantages are known, which result from the uncontrollable leakage losses of, for example, gaseous media ^. devoted to the general «on the incomplete; Completion and the leakage of the locking means of the gas containers and the distribution networks as well as the valves of the

In order to avoid all of the above parts and to avoid the larger and closer requirements with Bezusz; on the Security in the area of use, distribution and the consumption of gaseous Madien to be checked, which is getting wider because the application is on one large part of the population, the pressure regulator according to the present invention is for gaseous or liquid media has been developed in general, the task of which is to prevent any changes in the operating conditions of the distribution system and the consumer parts to avoid and to abolish = and consequently the outflow to prevent or interrupt gas.

For the above purpose it is provided according to the invention in the new pressure regulator that the diaphragm acted upon or loaded by the variable pressure of the medium is in operative connection with a swinging or pivoting element, which is on a pin in a bore for the = thin step of the fluid acts in the chamber delimited by the membrane and is connected to a movable clement via this pin, which is arranged in a chamber which is in a beech tree
