摘要:
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.
摘要:
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.
