Frictionless rotary valve

A frictionless rotary valve comprising:

• a valve body, to be connected within a gas meter, wherein the valve body comprising:
• an inlet connected to an outlet through a central chamber;
• and
• a seal, fixedly attached near the outlet, along an inner circumference of the valve body;
• a valve disc, having a ball bearing at a first end, wherein the ball bearing is attached to the valve body such that the valve disc is freely rotatable within the valve body;
• and
• a gear mechanism, to control a movement of the valve disc, wherein the gear mechanism comprising:
• a worm wheel engaged with a worm, wherein the worm wheel is attached to a second end of the valve disc;
• a drive gear connected to the worm, wherein a rotation of the drive gear in a clockwise direction rotates the worm wheel in an anti-clockwise direction such that the valve disc attached to the worm wheel moves in a closed position;
• a worm wheel stop, for restricting a movement of the worm wheel in the anti-clockwise direction by driving the worm wheel in a vertically upward direction;
• and
• a linear guide attached to the worm wheel, wherein a distance spring encloses a guide shaft of the linear guide such that a movement of the worm wheel in the vertically upward direction compresses the distance spring,
• wherein during an opening of the valve, the valve disc is moved in a direction of the linear guide and rotated afterward, and wherein in a closing of the valve, the valve disc is rotated and afterward moved in a linear direction to the closed position.
