。[Claims for Utility Model Registration] An oil supply pump consisting of a cylinder that communicates with an oil storage tank through an oil supply path and has a discharge port on one side, and a piston that reciprocates within the cylinder, the piston being moved by a constant hydraulic pressure. A port is provided between the cylinder and the oil storage tank, which is located at least in the direction of the discharge port from the oil pressure supply path and can return the oil in the cylinder to the oil storage tank by the oil pressure. A single plunger type oil supply pump, characterized in that a check valve that can be opened and closed by hydraulic pressure is attached to a discharge port connected to the cylinder, and a space is formed within the cylinder side end located in the direction from the port to the discharge port.
