PURPOSE:To obtain the feed oil amount adjusting mechanism of an oiler, by which a feed amount of oil can be set further visibly checked with ease from the outside even under the unpressurized condition, by turning a handle, on which a corresponding scale to the feed amount of oil is graduated, and adjusting the opening of a throttling mechanism. CONSTITUTION:A drop window 6 molded by a transparent material is provided on an upper part of the main unit 1, while a handle 19 is turnably inserted into the bottom face of a flange part of the drop window 6, and an adjusting slope 19a is formed on the bottom face of the handle 19 on the upper surface of which a scale 19b is graduated. The adjusting slope face 19a, having a gradient with the fixed proportion, moves a needle valve 18 against a spring 16 and fluid pressure by turning the handle 19, and the cross sectional area of an orifice, formed by a V-shaped groove 18a and a packing 15, is caused to vary, thus changing a feed amount of oil. |
