摘要:
An arrangement of a pressure limiting valve (1) for the pilot control of a pressure control valve of a hydraulically actuatable shifting element of a motor vehicle transmission in which the pressure limiting valve (1) is disposed such that the armature axis thereof is disposed perpendicular to at least one of the driving direction and the longitudinal axis of the vehicle.

A device for holding and positioning an endoscopic instrument introduced through a body surface of a patient has a holder for the instrument, which holder is designed in such a way that the instrument can be positioned relative to the body surface in different spatial tilt positions. The holder has a first bow-shaped element whose two end portions are arranged directed towards the body surface, and whose middle portion is directed away from the body surface, the first bow-shaped element being pivotable about a first pivot axis which extends through both end portions. The holder has a second bow-shaped element whose end portions are directed towards the body surface, but arranged offset by approximately 90° relative to the end portions of the first bow-shaped element, and whose middle portion is directed away from the body surface by substantially the same distance as the first bow-shaped element, the second bow-shaped element being pivotable about a second pivot axis which extends through both end portions of the second bow-shaped element, and both bow-shaped elements each having an opening which extends along said elements, and an overlapping region of the openings serving as a guide for the instrument.
摘要:
A simulator apparatus with at least two degrees of freedom of movement for an instrument that has an elongated shaft, having a holding device for the instrument, the holding device being designed such that the instrument has at least a first degree of freedom of a swiveling movement about a first swivel axis and at least a second degree of freedom of swiveling movement about a second swivel axis, running perpendicular to the first swivel axis. The holding device has a cardanic suspension that has a spherical element which is suspended such that it can rotate about the first swivel axis and about the second swivel axis, and in which the shaft is partly held.

A simulator apparatus with at least two degrees of freedom of movement for an instrument which has an elongated shaft, has a holding device for the instrument, the holding device being designed such that the instrument has at least a first degree of freedom of rotary movement about the longitudinal axis of the shaft and at least a second degree of freedom of translatory movement in the direction of the shaft. The holding device has a gear arrangement for the first and second degrees of freedom, which has a first bevel gear, which is connected to the shaft and corotates with the latter about the longitudinal axis thereof, and has a second and a third bevel gear which are arranged on either side of the first bevel gear and are in rolling engagement therewith.
