A pneumatic amplifier and arrangement for the points of a regulating valve of a technical system

摘要

In the case of a pneumatic amplifier comprising: an air feed valve with a supply input that can be connected to a pneumatic supply, a signal input for receiving of the pneumatic input signal, a signal output for outputting a reinforced pneumatic output signal, a valve member, in particular, for the continuous opening and / or interruption of the pneumatic connection between the pneumatic supply and the signal output and a diaphragm that is connected to the valve member, with the pneumatic input signal, which is acted upon by outer side and a defined outer side facing away from the signal input; and - an exhaust air valve with a vent port for venting of the amplifier and a valve member for the continuous opening and / or interrupting a pneumatic connection between the signal output of the supply air valve and the vent port wherein the valve elements of the feed air - and exhaust valve are structurally separate from one another, it is provided that the outer side of the diaphragm facing away from the signal input of the reinforced pneumatic output signal is applied.
