ABSTRACT:
A piezo valve arrangement for gas mixers or respirators, which is built up modularly from individual valve elements. At least one individual valve element, which is provided in its housing with a pressurized gas channel and a gas discharge channel, is arranged between a connection plate with a pressurized gas connection and a gas discharge connection, on the one hand, and a closing plate, on the other hand, wherein the direction of the gas flow in each valve element is from the pressurized gas channel via a metering screw, a metering channel, and a piezo vibrating element held freely vibrating on one side with a seal to the gas discharge channel.
