PURPOSE:To accurately perform the quantitative measurement of grease, by a method wherein a fixed quantity chamber is highly pressurized by a plunger prior to sending grease to a grease emitting nozzle under pressure to collapse air bubbles or air in grease to check the grease. CONSTITUTION:When a valve V1 is opened to supply grease into a fixed quantity chamber 11 under pressure and a limit switch LS1 is brought to ON-operation by the movements of a plunger 15 and a piston lever 16 to their retracted ends, the valve V1 is closed. Subsequently, the fixed quantity chamber 11 is highly pressurized by the plunger 15 and, if the plunger 15 is not advanced into the fixed quantity chamber 11, a valve V2 is opened because of no air bubbles in grease and the grease (g) in the fixed quantity chamber 11 is injected in and applied to a bearing B. On the other hand, when air bubbles are mixed in the grease, air bubbles are collapsed and the plunger is advanced little because of volume reduction. In this case, a manual opening and closing valve V3 is opened to introduce the grease into the fixed quantity chamber 11 and the grease having air bubbles mixed therein in the fixed quantity chamber 11 is discharged to drain D. |
