Summary: | A time delay valve (10) comprising: a switching valve (18) that switches between a first position and a second position; an urging member (20) that urges the switching valve (18) toward the first position; a driving mechanism (22) that urges the switching valve (18) toward the second position located opposite the first position in the presence of the pressure of a pilot fluid being supplied; a pilot flow channel (36) that introduces the pilot fluid to the driving mechanism (22); and a delaying mechanism (24) that delays the switching timing of the switching valve (18), wherein the delaying mechanism (24) includes a first throttle valve (34) provided on the pilot flow channel (36), a compensation mechanism (26) that urges the switching valve (18) toward the first position in the presence of the pressure of the pilot fluid being supplied, and a compensation flow channel (44) that is branched from the pilot flow channel to introduce a portion of the pilot fluid to the compensation mechanism (26). |
