PURPOSE:To eliminate bulk leakage by resucking the oil attached to a pin tip or excessive oil through the use of a diaphragm or a piston, at the time of oiling. CONSTITUTION:The oil contained in a body a is supplied by facing the place to be oiled and allowing a screw rod e to make a diaphragm d concave when a cap b is pushed. If thereafter the cap b is retracted, the diaphragm d returns to its initial position, and that portion of oil excessive and put outside once is also sucked in. If the cap b is further retracted, the diaphragm d is bent convex to the opposite direction to let the inlet to an oil conduct h open, and an insufficient amount of oil is refilled to inside the oil pin. |
