Title
(DE) AXIALKOLBENMASCHINE MIT HYDROSTATISCHER AUFLAGE DES NIEDERHALTERS
(EN) AXIAL PISTON MACHINE HAVING A HYDROSTATIC SUPPORT OF THE HOLD-DOWN
(FR) Machine à piston axial avec appui hydrostatique du serre-flan
Abstract
(DE)
Eine Axialkolbenmaschine umfaßt ein Gehäuse (1), welches eine Hubscheibe (3) sowie eine drehbar gelagerte Zylindertrommel (6) mit Zylindern (26,28) und in diesen hin- und herbewegbare Kolben (29) aufnimmt, deren aus den Zylindern (26,28) herausragenden Enden sich über Gleitfläche (31) einer Gleitscheibe (32) an der Hubscheibe (3) abstützen, sowie einen Niederhalter (36), durch welchen die Gleitfläche (31) in Anlage an der Gleitscheibe (32) gehalten werden. Ein in einem Druckraum (40) unter den Gleitschuhen (31) herrschender Druck kompensiert über eine Verbindungsdrossel (43) teilweise einen durch den Niederhalter (36) auf die Gleitschuhe (32) ausgeübten Druck.
(EN)
An axial piston machine comprises a housing (1) which receives an eccentric disc (3) and a rotatably mounted cylinder drum (6) having cylinders (26, 28) and pistons (29) which can move to and fro in the former and the ends of which which protrude out of the cylinders (26, 28) are supported on the eccentric disc (3) via a sliding face (31) of a sliding disc (32), and also comprises a hold-down (36), by which the sliding face (31) is held in contact with the sliding disc (32). A pressure which prevails in a pressure space (40) under the sliding shoes (31) compensates partially for a pressure which is exerted on the sliding shoe (32) by the hold-down (36), via a connecting restrictor (43).
(FR)
Machine à piston axial comprenant un boîtier (1) qui accueille une plaque (3) de levage ainsi qu'un tambour (6) cylindrique logé de manière à pouvoir tourner, comportant des cylindres (26, 28) et des pistons (29) pouvant effectuer un mouvement de va-et-vient à l'intérieur de ceux-ci, dont les extrémités faisant saillie hors des cylindres (26, 28) s'appuient sur la plaque (3) de levage par le biais d'une surface (31) de glissement d'une plaque (32) de glissement, ainsi qu'un serre-flan (36) par lequel la surface (31) de glissement est maintenue appliquée contre la plaque (32) de glissement. Une pression qui règne dans une chambre (40) de compression sous les patins (31) de glissement compense partiellement une pression exercée par le serre-flan (36) sur le patin (32) de glissement par le biais d'un obturateur (43) de liaison.
