Embodiment Construction

[0031] according to figure 1 The sealing device 10 has an elongated flexible sealing element 11 in the form of an endless rope, which is made of elastomer. The sealing element 11 is arranged in the groove 12 of the planar surface 14 of the first member 13, which is only partially shown. The plane surface 14 is opposite to the first member 13 in the installed state figure 1 The second member not shown in the figure forms a flat contact surface.

[0032] Furthermore, the sealing device 10 has an end element 15 which is arranged in a cutout 16 of the plane surface 14 of the first member 13. Likewise, the end element 15 is made of elastomer, wherein it is designed to be harder than the sealing element 11. The cut 16 is not deep enough so that the tip 16 can be completely received therein. During installation figure 1 For the second element not shown in, the end element 15 is slightly compressed for this reason. Therefore, it performs the sealing function between the two components...

Abstract

The arrangement has an elongated flexible sealing element (11) comprising a starting region (25) and an end region (19). The sealing element and an end element (15) comprise an overlapping area (23). The sealing element is displaceable relative to the end element such that a sealing edge (24) remains within the overlapping area during displacement of the end region towards the starting region. The end element exhibits a curvature (18), and the sealing element is arranged such that the sealing element rests along the curvature against the end element in a pressureless state. An independent claim is also included for a pump.

Description

Technical field [0001] The present invention relates to a sealing device according to the preamble of claim 1, and to a pump having a sealing device. Background technique [0002] It is known that the sealing device is provided between two members having a flat contact surface. Thus, for example, a pressure space formed at least partially by two members can be sealed. That is to say, especially for the case of pumps with separate housings, where the sealing device is provided between the two housing parts. [0003] In this connection, for example, so-called flat seals are used. These can be made of different materials, such as elastomers, compact fibers, aramid fibers, carbon fibers, mineral fibers, or metals, for example. Depending on the purpose of use, a matching flat seal can be selected. This type of seal can be used to achieve a good sealing effect. However, since the flat seal can only compensate for the small deformation of the contact surface, only a slight deformatio...
