Document Type and Number:
WIPO Patent Application WO/2012/025083
Kind Code:
A3
Abstract:
The invention relates to an abutment device (30) having a housing (31), in which at least one shape-memory element (120) is arranged, wherein an abutment element (32) mounted in the housing can be moved relative to the housing by means of a shape change of the shape-memory element caused by the supply of energy and can be reset by the discharge of a potential energy accumulator (36). The shape-memory element is guided in a liquid (130). An abutment device having increased operational reliability is developed by means of the present invention.
