- A housing with inlet and outlet channel,
- At least one piston guided in the housing,

Derartige Kolbenpumpen werden in großer Stückzahl für Bremsanlagen in Kraftfahrzeugen mit Antiblockiersystem (ABS) bzw. Antriebsschlupfregelung (ASR) benötigt, um Hydraulikflüssigkeit in den Hauptbremszylinder und/oder die Fahrzeugbremsen zu fördern.such Piston pumps are used in large numbers for brake systems in motor vehicles with anti-lock braking system (ABS) or traction control (ASR) needed, to hydraulic fluid in the master cylinder and / or to promote the vehicle brakes.
Aus der WO 95/168 59 A1 ist eine Kolbenpumpe bekannt, bei der der Kolben, die Rückstellfeder und die erste Ventilbaugruppe als eigenständig handhabbare Baugruppe zusammengefügt im Pumpengehäuse angeordnet sind. Bei der Montage muß diese Baugruppe am Ende der Rückstellfeder gefaßt und in die Kolbenbohrung des Gehäuses eingesetzt werden. Zu diesem Zweck ist die Rückstellfeder formschlüssig mit einem Ventiltopf verbunden, damit bei der Montage eine ausreichend sichere Verbindung zwischen der Rückstellfeder und dem Rest der Baugruppe hergestellt werden kann.Out WO 95/168 59 A1 discloses a piston pump in which the piston, the return spring and the first valve assembly as a self-contained assembly together in the pump housing are arranged. During assembly, this module must at the end of Return spring taken and into the piston bore of the housing be used. For this purpose, the return spring is positively with connected to a valve pot, so when mounting a sufficient secure connection between the return spring and the rest of the assembly can be produced.
Diese Gruppierung ist bei der Montage vergleichsweise aufwendig zu handhaben und störanfällig. Außerdem hat sich herausgestellt, daß die Handhabung der Baugruppe erschwert ist, weil sie am gegenüberliegenden Ende der Rückstellfeder gefaßt werden muß, wobei keine exakte Führung möglich ist, weil die Baugruppe über die Rückstellfeder mit dem Montagewerkzeug nicht starr, sondern nur elastisch verbunden ist.These Grouping is relatively complicated to handle during assembly and prone to failure. Besides, has turned out that the Handling the assembly is difficult because they are at the opposite End of the return spring to get nabbed must, where no exact guidance is possible, because the assembly over the return spring not rigid with the mounting tool, but only connected elastically is.

Es besteht die Aufgabe, eine Kolbenpumpe weiter zu verbessern, insbesondere im Hinblick auf eine noch preiswertere Herstellung und eine sichere Montage.It the object is to further improve a piston pump, in particular with a view to even cheaper production and safe installation.
Die Aufgabe wird mit der Gesamtheit der Merkmale des Patentanspruchs 1 gelöst.The The object is with the totality of the features of the claim 1 solved.
Die erfindungsgemäße Kolbenpumpe umfaßt demnach zwei Baugruppen, die jede für sich vormontiert und bei der Endmontage einwandfrei gehandhabt werden können. Die erste Baugruppe wird von einem Montagewerkzeug am hinteren Ende des Ventiltopfes erfaßt und in die Kolbenbohrung des Gehäuses eingesetzt, wobei eine sichere räumliche Zuordnung möglich ist, weil die Baugruppe – anders als beim Stand der Technik – ein in sich starres Gebilde ist. Gleiches gilt für die zweite Baugruppe, die die elastische Rückstellfeder enthält, und sicher zu positionieren ist, weil sie nicht an einem "elastischen Ende", sondern an einem "starren Ende" erfaßt und ausgerichtet werden kann. Ein weiterer Vorteil besteht darin, daß als Rückstellfeder normal gewickelte Schraubenfedern verwendet werden können, die gegenüber Sonderformen deutlich preisgünstiger sind.The piston pump according to the invention comprises Accordingly, two modules, each pre-assembled and at the final assembly can be handled properly. The first assembly is from an assembly tool at the rear end of the valve pot detected and in the piston bore of the housing used, with a secure spatial Assignment possible is because the assembly - different as in the prior art - a is in itself rigid structure. The same applies to the second module, the the elastic return spring contains and to be safely positioned because they are not grasped and aligned at an "elastic end" but at a "rigid end" can be. Another advantage is that as a return spring normally wound coil springs can be used across from Special forms significantly cheaper are.
