摘要： A radial piston pump has a pump body with two pump chambers lying in a straight line. In the pump chambers pistons reciprocate along this same straight line. The pump pistons are coupled to an actuator which is rotatable about an axis which bisects the straight line, and reciprocates the pistons in opposite directions. Each pump chamber is connected to an intake fluid duct and a discharge fluid duct, and the intake ducts are connected to a common main intake duct and the discharge fluid ducts to a common main discharge duct. An actuator controls operating components which co-operate with valve arrangements for the opening and closing of the fluid ducts.
