ADJUSTABLE AXIAL PISTON PUMP WITH REGULATING MECHANISM AND REGULATING MECHANISM FOR SUCH AXIAL PISTON PUMP

摘要

An axial piston pump capable fo swinging out to one side from the zero- stroke position is provided in which a force acting in the direction to the zero-stroke position engages on one side of a final control element and a spring force acting in the direction to the maximum stroke position engages on the other side, and the force acting in the direction to the zero-stroke position is produced by an operating cylinder-servo piston unit, whose servo piston is connected with the control bottom of the pump and a regulating unit is located in the servo piston in order to faciitate a minimal structural volume and cost, where this regulating unit preferably has two springs, one of which is supported against the housing and the second is supported against an auxiliary piston that is acted upon by the pressure beyond a restrictor in the delivery line.
