Regulating vacuum valve

A regulating vacuum valve comprising:

• a valve body with a through-channel;
• a closure member which is adjustable over a control path between a closed position of the regulating vacuum valve in which it contacts a valve seat and closes the through-channel and an open position of the regulating vacuum valve in which it is raised from the valve seat;
• an adjusting device which has a drive unit for adjusting the closure member over the control path;
• a carrying unit which carries the closure member, the closure member being displaceable relative to the carrying unit;
• wherein the carrying unit is arranged in the through-channel and is secured to the valve body;
• and
• wherein the carrying unit has a chamber which is sealed relative to the through-channel and in which the adjusting device or at least a portion thereof is arranged,
• wherein there is arranged at the closure member at least one valve rod with which an actuating part of the adjusting device cooperates,
• wherein the valve rod is supported in or at the carrying unit so as to be displaceable,
• wherein the carrying unit has a guide connection piece extending in direction of the closure member, the valve rod being supported in or at the guide connection piece so as to be displaceable,
• wherein a sealing ring is provided for sealing the chamber in the carrying unit relative to the through-channel and seals the valve rod relative to the guide connection piece.

• a carrying unit which carries the closure member, the closure member being displaceable relative to the carrying unit,
• wherein the carrying unit is arranged in the through-channel and is secured to the valve body,
• wherein the carrying unit has a chamber which is sealed relative to the through-channel and in which the adjusting device or at least a portion thereof is arranged,
• wherein the closure member is arranged outside the through-channel of the valve body.

A regulating valve comprising:

• a valve body with a through-channel;
• a closure member which is adjustable over a control path between a closed position of the regulating vacuum valve in which it contacts a valve seat and closes the through-channel and an open position of the regulating vacuum valve in which it is raised from the valve seat;
• wherein a sealing ring is arranged at the closure member or valve seat, which sealing ring contacts the other of these two parts in the closed position and seals the closure member relative to the valve body;
• an adjusting device for adjusting the closure member over the control path, which adjusting device has a drive unit;
• and
• an immovable carrying unit which carries the closure member and is supported so as to be displaceable relative to the carrying unit, wherein the carrying unit is arranged in the through-channel and is secured to the valve body, and the carrying unit has a chamber which is sealed relative to the through-channel and in which a portion of the adjusting device is arranged, wherein the adjusting device is guided out of the valve body so as to be sealed relative to the through-channel through the carrying unit and through the valve body.
