So, in the absence of armature movement which occurs either before the start of the direct stroke or after the return stroke, there is thermal contact between the active elements through the insulating liner.
at the end of the direct stroke of the working cycle.
4 shows the relative values (marked *) of the energy components during the direct stroke of the LPIEC work cycle.
This explains the low efficiency of the LPIEC, which at the end of the direct stroke is [eta] = 19.
After the direct stroke under the action of the spring 8, the armature 2 with the striker 4 is reversed, and the one-way valves 7 are closed.
