Title
(DE) KOLBENPUMPE
(EN) PISTON PUMP
(FR) POMPE A PISTON
Abstract
(DE) Die Erfindung betrifft eine Kolbenpumpe (10), die insbesondere zur Verwendung in einer schlupfgeregelten, hydraulischen Fahrzeugbremsanlage vorgesehen ist. Die Kolbenpumpe (10) ist in eine Zylinderbohrung (12) eingesetzt, sie weist einen Kolben (16), eine Laufbuchse (26) sowie ein die Zylinderbohrung (12) dicht verschließendes Verschlußelement (68) auf. Die Erfindung schlägt vor, das Verschlußelement (68) beispielsweise durch eine Verstemmung (70) radial beweglich mit der Laufbuchse (26) zu verbinden. Dies hat den Vorteil, daß sich die Kolbenpumpe (10) zu einer kompakten, gut handhabbaren und robusten Baugruppe zusammensetzen läßt, und daß sich Verschlußelement (68) und Laufbuchse (26) beim Einsetzen in die Zylinderbohrung (12) fluchtend zueinander ausrichten.
(EN) The invention relates to a piston pump (10) which is especially provided for a slip regulated hydraulic vehicle brake system. The piston pump (10) is arranged inside a cylinder bore (12) and contains a piston (16), a cylinder sleeve (26) and a sealing closing component (68). According to the invention, the closing component (26) is radially and movably connected to the cylinder sleeve (26), for instance, through a support (70). One advantage provided is that the piston pump (10) can be assembled with a compact, easy to manage and robust structural component so that the closing component (68) and cylinder sleeve (26) are aligned with one another when they are installed in the cylinder bore (12).
(FR) L'invention concerne une pompe à piston (10), destinée notamment à un système de freinage hydraulique de véhicule à antipatinage. Cette pompe (10) est insérée dans un alésage cylindrique (12) et présente un piston (16), une garniture (26) et un élément de fermeture (68) obturant de façon étanche ledit alésage cylindrique (12). Selon l'invention, il est prévu de relier l'élément de fermeture (68) à la garniture (26) de façon mobile dans le sens radial, par exemple par une partie matée (70). L'avantage de cette conception réside dans le fait que la pompe à piston (10) peut être assemblée pour former un module compact, robuste et facile à manipuler, et l'élément de fermeture (68) et la garniture (26) s'alignent précisément l'un par rapport à l'autre lors de leur introduction dans l'alésage cylindrique (12).
