摘要： A sealing arrangement for placement between two components which have a planar contact surface, in particular two housing parts of a pump. The sealing arrangement has an elongate, flexible sealing element whose end region has a termination element thereon, which can carry out a sealing function. The sealing element and the termination element have an overlap region in the end region of the sealing element and thus form a first continuous sealing edge. The sealing edge is maintained also for a displacement of the end region of the sealing element in the direction of the start region within the overlap region. The termination element moreover has a first curvature. The curvature and the sealing element are configured so that the sealing element contacts the termination element along the curvature in a pressure-free state.

摘要： The invention relates to a sealing arrangement for a high-pressure space having a bounding element and a termination element. The bounding element has an outer sealing surface and the termination element has an inner sealing surface. The outer sealing surface and the inner sealing surface are arranged such that a sealing-off of the high-pressure space is achieved via a contact of the two sealing surfaces. In accordance with the invention the bounding element is designed such that a force in the direction of the inner sealing surface can act on the outer sealing surface due to a pressure in the high-pressure space. Thereby a sealing function is also achieved then when the termination element deforms due to the pressure in the high-pressure space. The sealing arrangement in accordance with the invention can be used particularly advantageously in pumps.

摘要： Disclosed are a diffuser and a pump including a feed column extending around a diffusor axis of the pump and having a rotor housing which is arranged between an intake and a diffusor arranged in a diffusor section. During operation, fluid is sucked by the pump rotor via the intake, and is discharged from the feed column via the diffusor section, the feed tube and the outlet stub. The diffusor includes an inlet section arranged between an outlet section and the pump rotor, wherein a first part section adjacent to the inlet section is formed at the outlet section, the first part section is inclined with respect to the diffusor axis at a first angle (α). A second part section adjoining the first part section is inclined with respect to the diffusor axis at a second angle (β) different from the first outlet angle (α).
