Abstract
The invention relates to a displacement device (1, 31) provided with a first part (3, 33) with a primary coil (4, 34) and a second part (9, 39) with a secondary coil (10, 40), whereby the secondary coil (10, 40) can be moved in relation to the primary coil (4, 34) and is electrically connected to driving circuit. Once of the coils (4, 34) is an elongated coil, which extends in a travel direction, while the other coil (10, 40) can be moved in relation to the first coil (4, 34) in the travel direction.
Claims6
A displacement device (1, 31) provided with a first part (3, 33) with a primary coil (4, 34) and a second part which can be moved in relation to the first part (9, 39), the second part (9, 39) being provided with a secondary coil (10, 40) which can be moved in relation to the primary coil (4, 34) and which is electrically connected to an electrically driven element, characterized in that at least one of the coils (4, 34, 10, 40) is an elongated coil which extends in a travel direction, in that the other coil (4, 34, 10, 40) can be moved in the travel direction in relation to the first coil (4, 34, 10, 40).
A displacement device (1, 31) according to one of the preceding claims, characterized in that the secondary coil (10, 40) can be moved farther in relation to the primary coil (4, 34) in at least a direction that extends transversely to the travel direction.
