发明名称	Vacuum valve
摘要	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).
