Title:
LIQUID FORCE FEEDER
Document Type and Number:
Japanese Patent JP3026140
Kind Code:
B2
Abstract:
PURPOSE: To improve durability by successively providing a plurality of guide rollers in line with the sideward of a valve shaft operating rod, so that it can be slid only in a vertical direction, and further providing a valve unit for connecting/disconnecting between a sealed vessel and a force feed liquid discharge port in a float lever.
CONSTITUTION: A side surface of a slider 53 serving as a valve shaft operating rod is interposed by a plurality of guide rollers 48, and the slider can be moved only in a vertical direction. An upper end of the slider 53 is connected to a connection part 30 associated with a switching valve 120. Between the slider 53 and a float lever 52, spring receiving members 55, 56 and a coil spring 54 are interposed, and the spring receiving member 56 is connected to the slider 53 by a pin 76. One end of a double valve shaft 60 is swivelably connected through a pin 41 to the upper part of a float shaft 43. Double valves 61, 62 for connecting/disconnecting a force feed liquid discharge port 17 and liquid reservoir space 10 are mounted to the other end of the double valve shaft 60. Thus by preventing damage of a pin associated with the valve rod, durability can be improved.
