Abstract

PURPOSE: To make it possible to vary the delay time freely by a simple and low- cost structure, by using a combination of an air pressure leakage valve and an air electromagnetic valve.
CONSTITUTION: When rotary oil pump g is stopped, three-directional electromagnetic valve V1 has been closed, compressed air is not supplied from (IN) of three-directional valve V1 to its (OUT). Further, since the compressed air which has been supplied to reservoir tank R, air pressure leakage valve V3 and the piping between them escapes from exit (EXT) of three-directional electromagnetic valve V1 into the atmosphere, by letting this compressed air escape gradually by restricting it by means of miniature valve V2, it is possible to open air pressure leakage valve V3 some time later (normally after 0W60 sec) so as to operate the leakage of the piping. By this, it is possible to set a delay time as desired with high reliability.
