PURPOSE:To make an accurate fill-up stop at a preset value attainable, by making a preset fill-up possible only when a specified flow velocity is manually set in advance. CONSTITUTION:Oil out of an oil storage tank is supplied via a refueling nozzle 7. For example, a flow velocity of 25l/min is set down to a specified flow velocity, and a preset fill-up is made so as to be possible only when this specified flow velocity is manually set in advance, while a preset device consisting of a preset keyboard 13, a control element 11, a throttle valve V, etc., is installed in place. When the fill-up of oil is performed to the extent of a few quantities (20l-0.07l=19.93l) as little as a portion for the normal overrun quantity (for example, 0.07l) after the fill-up stop at the specified flow velocity rather than the preset fill-up quantity (for example, 20l), fill-up stop motion is achieved whereby the fill-up is accurately stopped at the preset fill-up quantity. |
