Patent ID: 8511642

Claim:
A closing unit for a vacuum valve comprising: a first valve plate for closing a first valve opening of the vacuum valve, a second valve plate for closing a second valve opening of the vacuum valve, a carrier plate that lies between the valve plates and to which the valve plates are fastened detachably, and at least one clamping piece by which interacting clamping surfaces are clamped to each other for fastening each of the valve plates to the carrier plate, at least one of the interacting clamping surfaces is constructed as an angular surface by which each of the valve plates is pressed onto the carrier plate, at least one clamping screw interacting with the clamping piece for clamping the clamping piece by exerting a clamping force onto the clamping piece, and a guide for each of the first and second valve plates, which is constructed between the respective valve plate and the carrier plate and by which the valve plate is guided along a guide path, wherein for joining the respective valve plate with the carrier plate, the valve plate is inserted in the guide and moved relative to the carrier plate along the guide path up to an end position in which the interacting clamping surfaces of the carrier plate and the valve plate, which are distanced before reaching the end position and approach each other when moving the valve plate along the guide path towards the end position, come into mutual engagement and wherein the guide secures the valve plate against lifting from the carrier plate.
