ヤ形オイルポンプ。 A drive gear that meshes with each other in a circular support hole formed in the pump housing, and an internal gear that sucks outflow from a suction port formed on the inner circumference of the support hole and discharges it from a discharge port by rotating the driven gear. In the type oil pump, a valve hole into which a valve member is slidably fitted into the pump housing is formed on a side of the support hole, and the valve hole has a relief that is opened and closed by sliding of the valve member. An internal gear type oil pump characterized in that a passage is formed in communication with the relief passage, and the relief passage extends in a tangential direction of the support hole and communicates with the suction port.
