Title
(DE) REVERSIERBARE AXIALKOLBENMASCHINE MIT LÄNGSVERSTELLUNG
(EN) LONGITUDINALLY ADJUSTABLE REVERSIBLE AXIAL PISTON MACHINE
(FR) MOTEUR A PISTONS AXIAUX REVERSIBLE A REGLAGE LONGITUDINAL
Abstract
(DE) Die reversierbare Axialkolbenmaschine (1) besteht auseiner um eine Rotationsachse (7) rotierenden Zylindertrommel (5), in der in Zylindern (6) Kolben bewegbar sind, die sich gegen eine Schrägfläche (8) abstützen. Der Stellwinkel (&agr;,1, &agr;.2) der Schrägfläche (8) ist durch eine Verstelleinrichtung (12) verstellbar. Der Stellwinkel (&agr;,l, &agr;,2), der in beiden Schwenkrichtungen verstellbar ist, wird durch einen Stellkolben (24) der Versteileinrichtung (12) verstellt, der sich im wesentlichen parallel zur Richtung der Rotationsachse (7) der Zylindertrommel (5) erstreckt. Die Nulllage der Verstellung der Schrägfläche (8) ist durch eine Nulllagenstelleinrichtung (32) spielfrei einstellbar.
(EN) The invention relates to a reversible axial piston machine (1) consisting of a cylinder drum (5) which rotates about a rotational axis (7) and in which pistons can be displaced in cylinders (6), said pistons being supported against an inclined surface (8). The angle of adjustment (&agr;1, &agr;2) of the inclined surface (8) can be adjusted in both pivoting directions by means of a control piston (24) pertaining to the adjusting device (12), said control piston extending essentially parallel to the direction of the rotational axis (7) of the cylinder drum (5). The zero position of the adjustment of the inclined surface (8) can be adjusted without play by means of a zero position adjusting device (32).
(FR) L'invention concerne un moteur à pistons axiaux réversible (1) composé d'un tambour de cylindre (5) tournant autour d'un axe de rotation (7), dans lequel des pistons (6) peuvent être déplacés dans des cylindres (5), lesdits pistons s'appuyant contre une surface inclinée (8). L'angle de réglage ($g(a)1, $g(a)2) de la surface inclinée (8) peut être réglé au moyen d'un dispositif de réglage (12). L'angle de réglage ($g(a)1, $g(a)2), pouvant être réglé dans les deux sens de pivotement, est réglé au moyen d'un piston de réglage (24) du dispositif de réglage (12), s'étendant essentiellement perpendiculairement par rapport à la direction de l'axe de rotation (7) du tambour de cylindre (5). La position nulle du réglage de la surface inclinée (8) peut être réglée sans jeu au moyen d'un dispositif de réglage de position nulle (32).
