摘要

The invention relates to an apparatus (12) for supplying a liquid under a constant pressure. A supply tank (32) has been disposed at a higher level than articles (11) to be supplied with the liquid, whereby an overflow plate (33) divides the interior of the supply tank into a main tank compartment (34) and an auxiliary tank compartment (35). Further there has been provided replenishing means for supplying a replenishment of the liquid to the main tank compartment at a rate in excess of the rate of supply by a supply pipe per unit time, and means for transferring the liquid from the auxiliary tank compartment to the main tank compartment at a rate in excess of the rate of supply. Control means operate the replenishing means and stop the transferring means upon the liquid level in the auxiliary tank compartment reaching a predetermined low level (58) and stop the replenishing means and operate the transferring means upon the liquid level reaching a predetermined high level (56).
