PURPOSE:To quickly supply oil mainly to an engine by forming two types of pump chambers is a distributer driven by the engine through a cam body while providing a plurality of paths for changing over one pump chamber respectively to inflow and outflow paths for an oil tank. CONSTITUTION:When an engine C is run under the empty condition of a lubricating oil pump B, a cam body 4 is operated. When the cam body 4 is pivoted while being vertically moved and a distributer 7 is vertically moved. When the distributer 7 is lowered to close a return path 16, a return path 16 so that oil from an oil tank A is taken into a second pump chamber 12 through a first inflow path 15. Also, oil in a second pump chamber 12 is taken into a first pump chamber 10 through a second inflow path 18 and a first change-over path 20. On the other hand, when the distributer 7 is lifted, oil in said chamber 10 is supplied from an outflow path 19 to the engine C. Also, oil in the second pump chamber 12 is returned to the oil tank A from a second change-over path 14 through the return path 16. |
