Abstract
(DE)
Ein Führungswagen (1) einer Linearführung umfasst einen Umlaufkanal (8) für Wälzkörper (2), welcher aus einem Lastabschnitt (3), zwei Umlenkabschnitten (5) und einem Rücklaufabschnitt (4) gebildet ist, wobei an einer in einem Schmiermittelkanal (10) angeordneten Übergabestelle (13) zur Zuführung von Schmierstoff zu einem der Umlenkabschnitte (5) ein Ventil (16) zur Verhinderung des Rückflusses von Schmiermittel aus dem Umlaufkanal (8) angeordnet ist und der Umlenkabschnitt (5) durch eine in einem Endstück (7) befindliche Umlenkschale (9) begrenzt ist. Das Ventil (16) ist einstückig mit mindestens einem der Elemente Umlenkschale (9) und Endstück (7) ausgebildet.
(EN)
The invention relates to a guide carriage (1) of a linear guide, comprising a circulation channel (8) for rolling elements (2) which is formed from a load section (3), two deflection sections (5) and a return section (4), wherein a valve (16) is arranged at a supply point (13) arranged in a lubricant channel (10) for the supply of lubricant to one of the deflection section (5) to prevent the back flow of lubricant out of the circulation channel (8), and the deflection section (5) is delimited by a deflection shell (9) located in an end piece (7). The valve (16) is formed integrally with at least one of the elements deflection shell (9) and end piece (7).
