Abstract

PURPOSE:To obtain the construction which can be used under high water pressure, by inserting the insulation spacer having the strength for pressure proof between the oscillator and the end cap and providing fine gap between the oscillator and the spacer to limit the concave of rubber boot. CONSTITUTION:The spacer 10 of insulator to keep the strength of water pressure and electric insulation is provided between the cylindrical type oscillator 1 and the end caps 3 and 4, the notch 10' is placed at a part of the spacer 10 and the coupled oscillation with the caps 3 and 4 is avoided by inserting the cushion 2 to the notch 10'. Further, the relation between the depth l and the thickness t of the cushion 2 has t>l, to produce fine gap between the oscillator 1 and the spacer 10 and the concave of the rubber boot 5 due to water pressure is limited to avoid the oscillation delivered to the caps 3 and 4 from the oscillator 1 to the spacer 10. Further, the stem 11 against the water pressure compressing the cushion 2 is placed to avoid the lowering in the preventive effect of the coupling oscillation through the compression of the cushion 2.
