ポンプ。In an automobile oil pump in which a drive gear and a driven gear that engages with the drive gear are disposed in a case, holes 6 are bored in the case in the axial direction of the four pumps, and the pumps intersect with the holes. A short-circuit path is provided that communicates the suction port and the discharge port, and a piston 7 capable of closing the short-circuit path is inserted into the hole 6, and the piston closes the short-circuit path when the oil discharge pressure is lower than a specified value. The case is pressed by a spring to a position where the passage is blocked, and the case is provided with a pressure transmission hole 10 that communicates with the oil main hole and opens into the hole 6. When the oil discharge pressure becomes higher than a specified value, It senses the oil pressure in the main hole, transmits the pressure from the pressure transmission hole, moves the piston against the spring, opens the short circuit, controls the oil discharge pressure, and saves engine horsepower.
