This study deals with the problem of the diagnostics of self-acting valves installed in reciprocating machines. Piston compressors and their valves are characterized. Compressor diagnostic systems, those offered and used, are described, including their restrictions. The signal generated by closing the valve is estimated. The authors have examined the relationship between the vibration signal and the condition of plate delivery valve of an air compressor. Simulations were made of the spring and plate wear and valve assembly errors. It has been shown that there is a relation between the selected vibration measure, mean peak-to-peak value of vibration accelerations and the technical condition of the discharge valve and measurement point. The authors have concluded, that in case of plate valves, one should expect that values of vibration measures depend on the measurement point and will decrease depending on its technical condition. A rule of diagnostic inference was formulated.
