Abstract
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.
