Ventilation pipe for oscillation starting device
Provided is a breather pipe for an oscillation starting device, which allows the inflow or outflow of air according to the differential pressure between the inside and outside of a housing, and which can prevent water from entering the housing even if the breather pipe is submerged in water. The present invention is provided with: a central passage (61) that is formed so as to extend from an inner section (31) to an outer section (32) of an oscillation-starting shaft (3); an inner opening (62) formed in the outer peripheral surface of the inner section (31); an air suction opening (63) formed in the surface of the outer part (32); an exhaust opening (64); an inner passage (65) that connects the central passage (61) and the inner opening (62); an intake passage (66) that connects the central passage (61) and the intake opening (63); and an exhaust passage (67) that connects the central passage (61) and the exhaust opening (64), in which an intake valve (7) that opens when the pressure in the housing becomes negative is disposed in the intake passage (66), and in which an exhaust valve (8) that opens when the pressure in the housing becomes positive is disposed in the exhaust passage (67).
提供一种起振装置用通气管，根据外壳内外的差压来允许空气的流入或流出，即使在没在水中的情况下，也能够阻止水侵入到外壳内。具有：形成为从起振轴(3)的内侧部(31)延伸到外侧部(32)的中央通路(61)；形成于内侧部(31)的外周面的内侧开口部(62)；形成于外侧部(32)的表面的吸气用开口部(63)；排气用开口部(64)；使中央通路(61)和内侧开口部(62)连通的内侧通路(65)；使中央通路(61)和吸气用开口部(63)连通的吸气用通路(66)；使中央通路(61)和排气用开口部(64)连通的排气用通路(67)，将在外壳内成为负压时开阀的吸气用阀(7)配置在吸气用通路(66)内，将在外壳内成为正压时开阀的排气用阀(8)配置在排气用通路(67)内。
