    • To easily change internal pressure of a container according to a change in external pressure.In a strain gauge device 100, a piston 54 attached to a tubular opening portion 53A provided at a housing part 53 slides in response to external pressure. Thereby varying the volumes of a regulator oil containing region 52 and a sensitive region 15 so as to achieve a balance with the external pressure, to change the internal pressure. Then, in the above-described strain gauge device, because the internal pressures of the regulator oil containing region 52 and the sensitive region 15 are changed according to a change in external pressure only by sliding of the piston 54, it is possible to easily perform regulation of the internal pressure. Further, because the above-described pressure balance mechanism 51 is achieved with a simple configuration, it is possible to easily perform regulation of the external pressure and the internal pressure even in a high-temperature/high-pressure environment.
    • 根据外部压力的变化容易地改变容器的内部压力。 在应变计装置100中,附接到设置在壳体部53的管状开口部53A的活塞54响应于外部压力而滑动。 从而改变调节器油容纳区域52和敏感区域15的体积,以实现与外部压力的平衡,以改变内部压力。 而且,在上述的应变计装置中,由于调节器油容纳区域52和敏感区域15的内部压力仅通过活塞54的滑动而根据外部压力的变化而变化,因此能够容易地进行 调节内压。 此外,由于通过简单的结构实现了上述的压力平衡机构51,所以即使在高温高压环境下也能够容易地进行外部压力和内部压力的调节。

    • In the valve mechanism 60, when a valve sleeve 62 and a valve plunger 63 move in an inside of a valve holder 61 by driving of a power unit 65, to be at a predetermined position, a coupling port 63C provided in a flow path 63A of the valve plunger 63 and a slit 610 in the valve holder 61 are communicated with one another, thereby connecting a regulator oil containing region 52 and a sensitive region 15, and in the case where the internal pressures of the regulator oil containing region 52 and the sensitive region 15 are different from each other, the pressures fluctuate so as to equalize those. On the other hand, when those are at positions other than the predetermined position, the coupling port 63C and the slit 610 are not communicated with one another, thereby cutting off the connection between the regulator oil containing region and the sensitive region, and therefore, it is possible to easily perform a pressure regulation even in a high-temperature and high-pressure environment.
    • 在阀机构60中,当阀套62和阀柱塞63通过驱动动力单元65在阀保持器61的内部移动到预定位置时,设置在流路63A中的联接口63C 并且阀保持器61中的狭缝610彼此连通,从而连接调节器油容纳区域52和敏感区域15,并且在调节器油容纳区域52和 敏感区域15彼此不同,所以压力波动,以使其均衡。 另一方面,当它们处于除了预定位置之外的位置时,联接口63C和狭缝610彼此不连通,从而切断调节器油容纳区域和敏感区域之间的连接,因此, 即使在高温高压环境下也可以容易地进行压力调节。
