Abstract

The invention relates to diagnostic methods according to the preamble of the equivalent claims 1 and 2 with which the state of a poppet valve in the course of the switching cycles and/or events thereof such as the occurrence of pressure shocks or surges during continuous operation is/are monitored continuously the measured signals are stored and the stored measured signals are interpreted in a targeted manner and early indication of cases of damage is carried out. According to a preferred variant of the diagnostic method said aim is achieved in that at the same time as the force time curve of the actuating force or the reaction force (F1(t); F2(t)) a displacement time curve (h(t)) of the displacement (h) of the at least one closing element (8*) is measured in that the force time curve of the actuating force or of the reaction force (F1(t); F2(t)) and the displacement time curve (h(t)) are combined with each other and used to determine a force displacement curve of the actuating force or the reaction force (F1(h); F2(h)) in that the current force displacement curve of the actuating force (F1(h)) or the reaction force (F2(h)) of a switching cycle in each case determined over the operating period or lifetime of the poppet valve (100) is compared with an earlier stored curve in that deviations are determined from the comparison in that within a predefined tolerance range for said deviations the latter are accepted and in that when said deviations exceed the predefined tolerance range a message and/or a control signal is/are generated.
