VALVE APPARATUS

Document Type and Number:

WIPO Patent Application WO/2007/099831

Kind Code:

A1

Abstract:

There is provided a highly convenient valve apparatus. A temperature sensor (150) is so provided as to project from a housing (15) into a tank internal space (12), so that the gas temperature in the tank internal space (12) can be directly detected with a high response, without receiving the effect of the heat capacity of, for example, the housing (15). A coil (17) for generating a magnetic force for driving a valve body (16) has terminals (173 to 175) formed at respective three places having respective different axis line directions, and a driving voltage is selectively applied between two terminals of the terminals (173 to 175). This enables the value of the driving current conducted through the coil (17) to be changed by selecting the terminals to which the driving voltage is applied even if the driving voltage is not controlled. Accordingly, without controlling the driving voltage, a large value of the driving current can be generated upon startup while reducing the value of the driving current during holding time, thereby preventing useless power consumption.
