Relay three types PR.1 is designed for implementing logical functions. The element can also be used for commutation of continuous signals. The relay consists of four sections, three flat rubber membrane associated in the membrane unit, and two nozzles. Section and the membrane form a four cameras - a, B, C, and Hard centres extreme membranes serve as dampers and together with the nozzles form a two pneumatomachi "the nozzle - valve".
When the element is in the active mode to the nozzle chamber And through the channel 11 is supplied to the supply pressure, when operating in passive mode input signal. In chamber B and through the channels 2, 12 is supplied to either the input signal or the back pressure. The pressure overpressure is determined by the circuit element: if under the influence of backwater nozzle supply must be closed, the back pressure is set to about 0.9 kgf/cm2 (90 kPa), in another case of 0.4 kgf/cm2 (40 kPa). The chamber G is fed to the input or she through the channel 13 communicates with the atmosphere. All .modes of operation the output signal is taken from the communication connecting channels 1 and 3. Under the total influence of the input pressure and the backup pressure in a static state membrane unit is in one of the end positions of the circuits of the relay.
Relay type PR.C differs from relay type PR.1 in that in the chamber G is installed spring. For normal operation of the element in the mode of denial need to be stabilized to a single value of the signal fed into the chamber B. the pressure Drop at the switching moment can cause component failure.
