    摘要: The pump includes a housing containing a hollow elongated part, a piston arranged to move back and forth inside an elongated part, an inlet port and an outlet port arranged so that a fluid can be sucked through the inlet port into a chamber during an instroke of the piston and expelled through the outlet port during an outstroke. A linearly and/or angularly actuable valve system has a valve holder mounted on the pump housing which includes at least one through-hole extending from the piston chamber to the housing outer surface. The valve holder contains an inlet and/or outlet to alternately connect the inlet and outlet ports of the volumetric pump.

    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.
