Title: Oil feeder
Inventor: MOTOSUGI KENJI
IPC: B67D7/08
Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To prevent an oil feed nozzle main body itself from becoming heavy in weight by providing a meter as a unit separate from the oil feed nozzle main body, adapting an oil feed quantity information generating unit which converts information on an oil feed quantity metered by the meter into a fluid pressure to be outputted, and providing a display unit for displaying the oil feed quantity to the oil feed nozzle main body. SOLUTION: When oil feed operation is performed by an oil feed nozzle main body 10, compressed air is intermittently sent to an output port 45 from a compressed air introducing port 44 through a through-hole formed concentrically with and at a fixed interval from a disc 42 which is provided in a meter 20 and which rotates in the number of rotations proportional to the metering of oil feed. When this compressed air acts on a super-low pressure air actuating valve 46 as a pilot pressure, the valve 46 converts compressed air sent from another compressed air source into an air pulse which is an information transmission medium of an oil feed quantity and sends this air pulse to an air cylinder in a display unit 60.  Then, the air cylinder inputs the air pulse to reciprocate and allows a numerical drum to rotate and the display unit 60 to display an integrated flow rate (oil feed quantity) which passes through a metering gauge 40.
