Abstract
A float chamber is defined within a body, which is also formed with an inlet passage for supplying fluid into the float chamber, and an outlet passage for taking fluid out from the float chamber opening into a lower part of the float chamber. A float is mounted within the float chamber so as to be movable up and down, and acts on a fluid valve for controlling fluid flow into the float chamber through the intake passage, causing the valve to open and close. The shapes of the float and the float chamber are such that the amount of fluid required to be present in the float chamber in order to float the float at the position in which it just causes the valve to be closed, in equilibrium between its weight and the buoyancy force exerted by the fluid, is independent of the angle of tilting of the float chamber within a certain tilting range.
