Abstract

PURPOSE: To enable lubricant to be automatically restored to suction side as well as permit the switching of feeding liquid from the tank A to the tank B or vise versa at our disposal by turning one gear pump normally or reversely.
CONSTITUTION: The switching valve case 4 operated by the electromagnetic valves 2 and 3 is attached to the gear case 1 provided with the recycling paths 7 and 8 having the charging and discharging openings 5 and 6. When the gear pump is put into the normal rotation a, the opening 9 of the switching valve 4 is connected to the recycling path 7 and then to the charging and discharging opening 6. Thus, feeding liquid is freely switched from the tank A to the tank B or vice versa by turning the gear pump normally or reversely and also the lubricant, etc. of bearing can be automatically sent back to the suction side, permitting the simplification of facilities.
