Gas-blast switch actuatable by a mechanical drive by means of a drive element

Abstract

A drive element coupled with a mechanical drive is guided out of a switch housing through a through-passage housing containing a liquid bath. In the liquid bath there is immersed a hydraulic damping device containing a cylinder and piston and cooperating with said drive element, so that, with virtually no additional constructional expenditure at the drive, there is achieved a dependable braking of the drive element towards the end of a switching stroke. The piston of the hydraulic damping device is connected by means of a drag connection with the drive element. This drag connection includes at least one entrainment rod connected with the piston and acted upon by an entrainment collar provided at the drive element.
