<p><P>PROBLEM TO BE SOLVED: To provide a fluid tank which reduces an exclusively possessing space of the whole system using hydraulic pressure, facilitates installation work, and surely removes bubbles. <P>SOLUTION: A cyclone type bubble removing device 30 is arranged in a hydraulic tank 1. Accordingly, it is no longer necessary to secure a space for installing a bubble removing device 30 outside the tank 1 and hence the space dedicated to the hydraulic system is reduced. Since the bubble removing device 30 is fitted to the inside of the hydraulic tank 1 in advance, it does not need to be installed separately somewhere in the hydraulic circuit so that the installing operation can be performed quickly. Additionally, the outflow ports 322 for causing hydraulic fluid from which bubbles have been removed to flow out, and the exhaust port 333 for expelling bubbles are arranged separately so that it is possible to expose the exhaust port 333 is guided and opened up to the drain space 127. Thus, if the hydraulic tank 1 is rocked to a large extent, the hydraulic fluid coming out of the outflow ports is not mixed with bubbles and hence bubbles are eliminated reliably. <P>COPYRIGHT: (C)2004,JPO</p> |
