Abstract
In a housing of a pump apparatus having a flow control valve to discharge a part of excess fluid in a deviated slanting way to a bypass pass, a pair of suction paths' is formed opposite to end portions′ of the bypass pathto send operation fluid to suction ports of the pump apparatus. A dividing wall is equipped at opening portions of said pair of suction paths′ to distribute the operation fluid to each of suction paths′. A cross sectional area of one of said opening portions in a side of a direction of said deviated slanting way is smaller than a cross sectional area of the other of said opening portions in an opposite side of the deviated slanting way to relatively restrict a flow of said operation fluid in said one of opening portions.
