Abstract
Official abstract text for this publication.
A vacuum valve having a valve rod ( 11 ) which has a longitudinal axis ( 20 ) and which carries at least one closing member ( 9, 10 ) for closing at least one valve orifice ( 2, 3 ) and which can be displaced by a longitudinal drive ( 18 ), in a longitudinal direction ( 21 ) lying parallel to the longitudinal axis ( 20 ) of the valve rod ( 11 ), from an initial position, in which the vacuum valve is open, into an intermediate position and can be displaced by a transverse drive ( 19 ) from the intermediate position to at least one end position in which the vacuum valve is closed. A transmission piece ( 23 ) which is guided displaceably in the longitudinal direction ( 21 ) by at least one guide part ( 24 ) is secured to the valve rod ( 11 ). At least one transverse drive part ( 26 ) of the transverse drive ( 19 ) engages on the guide part ( 24 ), the guide part ( 24 ) being displaceable in the transverse direction ( 22 ) by the transverse drive ( 19 ) via the at least one transverse drive part ( 26 ), and the guide part ( 24 ), during its displacement in the transverse direction ( 22 ), taking along the transmission piece ( 23 ).
