The solution concerns a connection of pneumatic valve. The principle of the solution consists in the connection of a small compressor without air receiver, optimally of a car compressor for inflating tyres, onto signalling pressure piping, in which the air pressure is lead from the compressor (1) through back pressure valve (3) to pressure switch (4), electromagnetic three-way valve (5) with air outlet (6) through pressure meter (7) to diaphragm (8) of pneumatic valve (9) with closing segment (10), while the compressor (1), the electromagnetic valve (5) and the pressure switch (4) are parallel connected by means of a wire (11).<IMAGE>
