Abstract

PURPOSE: To obtain full performance of a pair of pumps by connecting pressure difference mechanisms to receiving pressure control surfaces of control valve means and thereby by controlling a power difference between the pumps, below the prescribed level.
CONSTITUTION: In control valve means C, D receiving pressure control surfaces 5a, 6a are formed. To said surfaces 5a, 6a pressure difference control mechanisms 13, 14 are connected. When a pressure difference between a pair of first and second pumps A, B is more than a predetermined level, a pressure balancing against the force of pressure applying member 9, 10 is lowered by increasing pressure receiving areas of the spools 5, 6 to control the power difference between the pumps A, B below the prescribed level. With this, a large bending moment does not act on a driving shaft and thereby full performance of the two pumps is obtained.
