Description

Sternpumpe Die-Erflndung bezieht sich auf gternpüm-:pen oder -motoren mit radial angeordneten Zylindern und feststehender Welle, durch die das Betriebsmittel - zugeführt wird, -'und,. :mit verstellbarer oder nichtverstellbarer Exzentrizität des äußeren , Lagerringes, in welchem der die kölbeiikUpf# - aüfrrhmen@le= Gegexilagerring umläuft. Solche Sternpumpen oder -inotoren mit radial angeordneten Zylindern sind bereits bekanntgeworden.. Bei diesen; erfolgte jedoch die Anordnung: in- der- Weise, daß die Kolbenköpfe drehliär * liziv. -gelenkig -mit dem Gegenlagerring verbunden sind.Star pump The invention relates to pumps or motors with radially arranged cylinders and fixed shaft through which the equipment - is supplied, -'and ,. : with adjustable or non-adjustable eccentricity of the outer, bearing ring, in which the kölbeiikUpf # - aüfrrhmen @ le = Gegexilagerring running around. Such star pumps or -inotors with radially arranged cylinders are already become known .. With these; however, the arrangement was made: in such a way, that the piston heads are rotationally * licit. - articulated - connected to the counter bearing ring are.

Demgegenüber besteht die Erfindung darin,-daß die Kolbenköpfe beiderseitig in der Umlaufrichtung durch Federn nach Art. elastischer Wellenkupplungen im Gegenlagerring abgestützt sind: Hierdurch wird erreicht,- daß sämtliche Kolbeneiner Sternpumpie oder eines Sternmotors gleichmäßig, belastet werden, so daß nicht an einzelnen Kolben auf Kosten der übrig ,en eine unerwünscht hohe Belastung und die damit verbundene Reibung auftritt, die sonst zu einem vorzeitigen Verschleiß einzelner Kolben führen. muß.In contrast, the invention consists in -that the piston heads on both sides in the direction of rotation by springs according to the type of elastic shaft couplings in the counter bearing ring are supported: This achieves - that all pistons of a star pump or a radial engine are evenly loaded, so that not on individual pistons at the expense of the rest, en an undesirably high burden and the associated Friction occurs, which otherwise lead to premature wear of individual pistons. got to.

Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt, und zwar üach Fig. i irii Längsschnitt und nach Fig.@@ im waagerechten Schnitt.The drawing shows an embodiment of the subject matter of the invention shown, namely üach Fig. i irii longitudinal section and after Fig. @@ in the horizontal Cut.

Der Zylinderbock i dreht, sich um die. mit Zu- und @ Abflüßleitungen versehene fest- stehende Welle z. In den Zyliuderbohrun- gen 3 - in der Fig. i sind es beispielsweise acht - bei?#egen sich die Kolben ¢, die so in dem Gegenlagerring 5 aufgehängt sind, däß sie außer in. der Umfangsrichtung relativ zum Gegenl.agerrirng 5 etwas' Spiel haben und auch noch entsprechend. der- Exzentrizität zwi- s;chen Zylinderblock und Gegenlagerring in ihrer Aufihängung pendeln können. Die üb#er- tragung des Drehmomentes von sämtlichen Kölhenenderi q." -auf den Gegenlagerring er- folgt nun über Federn 6, die eine vollkommen gleichmäßige Verteilung der an den Kolben- ring bewirken. Zwecknnäßigerw@eise ist der Gegenlagerring für die Kolben an seinem äußeren Umfang auf Nadel- oder Rollen- -lagern gelagert. The cylinder block i rotates around the. with Inflow and @ outflow pipes provided with fixed standing wave z. In the cylinder bore gen. 3 - in Fig d i sin it, for example, eight - at? # lie the pistons ¢, the so are suspended in the counter bearing ring 5, that they are relative except in the circumferential direction to Gegenl.agerrirng 5 have some play and also accordingly. the- eccentricity between see cylinder block and counter bearing ring in their suspension can swing. The above- transmission of the torque from all Kölhenenderi q. "- on the counter bearing ring now follows over springs 6, which is a perfect one uniform distribution of the ring effect. That is expedient Counter bearing ring for the piston on his outer circumference on needle or roller -store stored.
