The engine with a variable flow rate oil pump includes a subsidiary relief passage that extends from an oil passage-switching valve to a subsidiary oil pump, a main relief passage that extends from the oil passage-switching valve to the main oil pump separately from the subsidiary relief passage, and a check valve that is provided in the subsidiary discharge passage and cuts off the flow of oil from the main discharge passage side to the oil passage-switching valve side. The oil passage-switching valve has a main pressure-adjusting chamber for the main oil pump, a subsidiary pressure-adjusting chamber of for the subsidiary oil pump, and a spool valve that performs partitioning between the main pressure-adjusting chamber and the subsidiary pressure-adjusting chamber.
