PURPOSE:To prevent the malfunction due to oscillation by a method wherein an oil piping system which connects the titled apparatus to an impact oil pressure relay is provided with an orifice. CONSTITUTION:The relay consists of an oil chamber 3, a micro switch acting bellows 4, an air chamber 5, an equalizer 6, a separate bellows 2, a micro switch 10, and the like. In the case of accident, oil power compresses the bellows 2 via oil in the chamber 3. The compression of the bellows 2 allows the switch 10 to operate by the elongation of the bellows 4. The orifice 21 inhibits the resonance of a connection pipe system which connects the relay and the apparatus, thus preventing the malfunction due to earthquakes and the like. |
