Title:
ドライクリーナ
Document Type and Number:
Japanese Patent JP3091658
Kind Code:
B2
Abstract:
PURPOSE: To prevent the idling of a self-feeding type pump for a washing liquid by placing at least a part of the liquid feed path on the downstream side of selector valves upper than this pump and executing a stroke for enhancing the self-feeding performance of the pump by stopping the pump and holding the selector valve open for a specified time after the end of a dehydrating stroke. CONSTITUTION: The pump P for supplying the washing liquid from a solvent tank 11 to a drum 1 is of a self-feeding type. At least a part of the liquid feed path on the downstream side of the selector valves 122, 121 disposed in the respective inlets of a filter F and a bypass path 120 is positioned upper than the pump P. The solvent is discharged from the drum 1 after the end of the washing stage. Further, the drum is rotated forward at a high speed to remove the liquid. The drum 1 is stopped to end the dehydrating stroke when a prescribed dehydrating time elapses. The pump P is stopped for a prescribed period of time and the selector valve 121 is opened and the selector valve 122 closed to allow the solvent in the flow passage to gravitationally fall into the pump P by utilizing the fall in the stroke for enhancing the self-feeding performance of the pump P after the end of the dehydrating stroke, by which the self-feeding performance of the pump P is enhanced.
