Vacuum valve system for a vacuum transport system

A vacuum valve system for substantially gas-tight closure of a valve opening for a vacuum transport system, wherein the vacuum transport system comprises a transport tube for transporting an object inside along the transport tube,

• comprising
• a valve seat arrangement which has the valve opening , a first valve seat surrounding the valve opening and a second valve seat surrounding the valve opening,
• a closure component for gas-tight closure of the valve opening with a first sealing surface and a second sealing surface, wherein the first sealing surface corresponds to the first valve seat and the second sealing surface corresponds to the second valve seat, and
• a drive unit for providing a movement of the closure component relative to the valve seat arrangement such that the closure component moves from an open position, in which the closure component at least partially clears the valve opening, in the closing direction into a closed position, in which the first sealing surface is in an opposing position relative to the first valve seat and the second sealing surface is in an opposing position relative to the second valve seat, and back, wherein
• the closure component has a first closure side with the first sealing surface and a second closure side with the second sealing surface,
• the closure component has a closure body which is arranged between the first closure side and the second closure side and connects them,
• the closure body and the closure sides are designed in such a way that the closure component has at least one first recess that is open towards the edge of the closure component, and
• an opening of the at least first recess faces in the closing direction.
