Abstract:
Liquids escape through openings in the housings of pressure-regulating valves when the internal pressure of the liquids inside the housings increase. This pressure-regulating valve is equipped with: a cover section which covers an opening and includes a peripheral section for surrounding the opening when seen in a planar view; a sealing section which is positioned between the peripheral section of the cover section and the surface of the housing; an elastic member which produces biasing force in a first direction which biases the cover section toward the housing; and a base section which is secured to the housing and supports the elastic member in a manner such that the elastic member expands and contracts in the first direction.
