Summary:The pump has a valve (9, 19) with valve body (12), and a spring (4) attached to the valve body by a spring pot (8) and to the piston. The piston may be made as a unit with the return spring, with the spring and valve seat carrier able to form a larger assembly unit. The pot may fit in a recess (8) in the valve seat carrier. The pump has a valve (9, 19) with valve body (12), and a spring (4) attached to the valve body by a spring pot (8) and to the piston. The piston may be made as a unit with the return spring, with the spring and valve seat carrier able to form a larger assembly unit. The pot may fit in a recess (8) in the valve seat carrier. Die Erfindung betrifft eine Kolbenpumpe für regelbare Bremssysteme wie ABS, ESP. Die in Großserien herzustellenden Pumpen sollen so preiswert und einfach montierbar sein wie möglich. Hierzu schlägt die Erfindung vorsprüfbare und einstückig handhabbare Montagebaugruppen vor, die aus dem mit einem Ventilkörper (12) bestückten Ventil (9, 19) sowie die an den Ventilkörper ggf. über einen Federtopf (8) gefesselte Feder (4) bestehen. Ergänzend oder abweichend kann der Kolben (52) selbst mit der Rückholfeder (51) zu einer bestückbaren Einheit zusammengefasst sein, wobei die Feder (51) zusätzlich noch mit dem Ventilsitzträger (54) zu einer größeren Montageeinheit vereint sein kann.
