Abstract
Die Pumpe weist ein Gehäuse (10) mit wenigstens einer die Innenseite des Gehäuses (10) mit der Außenseite des Gehäuses (10) verbindenden Bohrung (40) auf, die mittels einer von der Außenseite des Gehäuses (10) her in die Bohrung (40) eingepressten Verschlußkappe (46) verschlossen ist, wobei die Verschlußkappe (46) topfförmig ausgebildet ist und mit ihrem offenen Ende zur Außenseite des Gehäuses (10) weist. In die Bohrung (40) ist wenigstens ein Ringeinstich (42) eingebracht. In die Verschlußkappe (46) ist von der Außenseite des Gehäuses (10) her ein Einsatzteil (56) mit gegenüber der Verschlußkappe (46) größerer Festigkeit eingepresst und durch das Einsatzteil (56) wird die Verschlußkappe (46) unter plastischer Verformung in den wenigstens einen Ringeinstich (42) der Bohrung (40) gepresst. The pump has a housing (10) with at least one bore (40) connecting the inside of the housing (10) to the outside of the housing (10), which is inserted into the bore (40) from the outside of the housing (10) ) Pressed closure cap (46) is closed, the closure cap (46) being cup-shaped and with its open end facing the outside of the housing (10). At least one ring recess (42) is made in the bore (40). From the outside of the housing (10), an insert part (56) with greater strength than the closure cap (46) is pressed into the closure cap (46) and the closure cap (46) is plastically deformed into the at least by the insert part (56) a ring recess (42) of the bore (40) is pressed.
