    Abstract: Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Regelung eines Drehmoments einer Triebwelle (4) einer hydrostatischen Maschine (5). Die hydrostatische Maschine (5) weist eine Stellvorrichtung zur Einstellung des Hubvolumens der hydrostatischen Maschine (5) auf. Das Verfahren weist folgende Schritte auf : Ein Soll -Drehmoment wird vorgegeben und ein eingestelltes Hubvolumen der hydrostatischen Maschine (5) erfasst. Ein Volumenstrom in die oder aus der Stellvorrichtung wird mittels eines Regelventils (19) zum Einstellen des Hubvolumens auf der Basis einer Kraftdifferenz zwischen einer Steuerkraft und einer in entgegengesetzter Richtung an dem Regelventil (19) angreifenden Kraft geregelt. Die Steuerkraft wird in Abhängigkeit des erfassten Hubvolumens und des erfassten Soll -Drehmoments bestimmt. Die in entgegengesetzter Richtung an dem Regelventil (19) angreifende Kraft ist eine hydraulische Kraft, die durch den an der Hochdruckseite der hydrostatischen Maschine (5) anliegenden Druck erzeugt wird.

    Abstract: A power pump performance analysis system and methods includes a signal processor connected to certain sensors for sensing pressures and stresses in the cylinder chambers and the inlet and discharge piping of a single or multicylinder pump. Pump speed and pump piston position may be determined by a crankshaft position sensor. Performance analyses for pump work performed, pump cylinder chamber stress, pump fluid end useful cycles to failure, and crosshead loading and shock analysis are provided for estimating pump component life and determining times for component replacement before failure.

    Abstract: A capacity control device in a variable capacity hydraulic pump comprising: a capacity control piston (6) provided with a large diameter chamber (7), for operating a capacity control member (5) of the variable capacity hydraulic pump (1) in a direction of decreasing or increasing the capacity by supplying or discharching pressure oil to or from said large diameter chamber (7); a first control valve (8) and a second control valve (9) for selectively allowing said large diameter chamber of said capacity control piston to communicate with a pump discharge path or a tank; said first control being set to a supply position by the pump discharge pressure and to a drain position by a spring linked with said capacity control piston through a feedback lever, and said second control valve being set to a first position for establishing communication between the pump discharge path and said large diameter chamber by the pump discharge pressure and to a second position for establishing communication between said large diameter chamber and said first control valve by negative pressure; wherein a flow sectional area of an oil path between said large diameter chamber and the pump discharge path or the tank is changed. With this arrangement, a change in the flow sectional area in an intermediate portion of the oil path can change the supply or discharge speed of the pump discharge pressure to the large diameter chamber of said capacity control piston, whereby the responsiveness of the capacity control of said variable hydraulic pump can be regulated, thereby improving the operability of a working machine.
