摘要： A pump for applying fluid, the pump including: a pump housing, including: a fluid inlet on a low-pressure side; an fluid outlet on a high-pressure side; a circumferential wall surrounding the pump delivery chamber; and an end-facing wall featuring an outer end-facing surface facing axially away from the delivery chamber and at which the outlet emerges; a delivery member, moveable in the delivery chamber, for delivering the fluid from the low-pressure side to the high-pressure side; a gasket including a gasket loop which surrounds the outlet to seal it off on the outer end-facing surface of the end-facing wall; a female joining element featuring an axially extending hollow space; and a male joining element protruding through or from the pump housing or the gasket. The male joining element is in a joining engagement, which can be subjected to axial tensile stress, with the female joining element in the hollow space.

摘要： A pump, comprising a pump insert which is arranged in an accommodating space of a cup-shaped pump housing. The pump insert comprises a first housing part and a second housing part between which a rotor is rotatably arranged, and a stroke ring which surrounds the rotor and is arranged between the first housing part and the second housing part. A spring flexing along the rotational axis is arranged between the accommodating housing and the second housing part. The spring comprises a spring structure which is made of metal and which imbues the spring with its essential spring characteristics along the rotational axis. The spring is supported towards the second housing part in a region which is arranged in axial alignment with the stroke ring in the direction of the rotational axis, and thus presses the second housing part against the stroke ring.
