Abstract
Die Pumpe weist wenigstens ein Pumpenelement (10) auf, das einen in einer Hubbewegung angetriebenen Pumpenkolben (12) aufweist, der in einer Zylinderbohrung (20) eines Gehäuseteils (22) der Pumpe verschiebbar geführt ist und in der Zylinderbohrung (20) einen Pumpenarbeitsraum (24) begrenzt, wobei der Pumpenarbeitsraum (24) über ein Einlassventil (26) mit einem Zulauf (28) und über ein Auslassventil (30) mit einem Ablauf (32) verbindbar ist. Das Einlassventil (26) und das Auslassventil (30) weisen jeweils ein Ventilgehäuse (56,78) auf, die in einer Aufnahme (54) eines Pumpengehäuseteils (22) angeordnet sind. Die Aufnahme (54) ist zumindest annähernd koaxial zur Zylinderbohrung (20) in einem an diese anschließenden Endbereich (52) des Pumpengehäuseteils (22) angeordnet, in dem die Zylinderbohrung (20) ausgebildet ist, und die Ventilgehäuse (56,78) des Einlassventils (26) und des Auslassventils (30) sind mittels eines das Pumpengehäuseteil (22) auf dessen die Aufnahme (54) umgebender Außenseite übergreifenden Befestigungselements (86) im Pumpengehäuseteil (22) gehalten.The pump has at least one pump element (10) which has a pump piston (12) driven in a lifting movement, which is displaceably guided in a cylinder bore (20) of a housing part (22) of the pump and in the cylinder bore (20) has a pump working space ( 24), wherein the pump working space (24) can be connected via an inlet valve (26) to an inlet (28) and via an outlet valve (30) to a drain (32). The inlet valve (26) and the outlet valve (30) each have a valve housing (56,78) which are arranged in a receptacle (54) of a pump housing part (22). The receptacle (54) is arranged at least approximately coaxially with the cylinder bore (20) in an adjoining end region (52) of the pump housing part (22) in which the cylinder bore (20) is formed and the valve housings (56, 78) of the inlet valve (26) and the outlet valve (30) are held in the pump housing part (22) by means of a pump housing part (22) on its outer side surrounding the receptacle (54).
