The invention relates to a metering valve () for a gaseous medium, in particular for a gaseous fuel, comprising a preferably planar valve seat element () having at least one flow-through opening () for the gaseous medium, a closing element () movable in a stroke-like manner and interacting in a sealing manner with the valve seat element () in order to release and close the at least one flow-through opening (), and a corrugated or folding bellows () connected to the closing element () for delimiting a compensation space (), which is connected to a pressure space () via a recess () formed in the closing element () so that the same gas pressure prevails in both spaces () irrespective of the switched position of the metering valve (). According to the invention, the compensation space () is arranged on the side of the closing element () facing the valve seat element () and is delimited in the axial direction by a pressure surface () which is formed on the closing element () or on a component () connected to the closing element (), in particular a flange component.

The invention relates to an electromagnetically actuatable gas valve for metering a gaseous fuel into a suction tract of a motor, in particular a gas or diesel gas motor, comprising a valve seat () which is designed as a flat seat and which has multiple annular webs () that are arranged in a concentric manner and are connected via at least one radially running web () in order to delimit circular or semicircular through-flow openings (). The electromagnetically actuatable gas valve further comprises a movable valve plate () which sealingly interacts with the valve seat () and which has multiple annular sealing webs () that are arranged in a concentric manner and can be brought into an overlapping arrangement with the circular or semicircular through-flow openings () of the valve seat (). According to the invention, the rigidity of the valve seat () and/or the valve plate () is substantially constant in the radial direction, the rigidity of the valve seat () being greater than the rigidity of the valve plate (). The invention further relates to a method for increasing the seal of an electromagnetically actuatable gas valve.

An elevator with a brake device for braking a car and/or keeping it stationary on at least one braking rail. The brake device has at least two brake shoes situated opposite from each other, and at least one brake clamp with two clamp arms for opening and closing clamp jaws acting on the brake shoes. In certain embodiments, only one of the clamp arms is connected to the car in pivoting fashion via a bearing with a pivot axle that is affixed to the car, oriented parallel to the direction of travel. In certain embodiments, the brake clamp is supported on the car in such a way that the clamp jaws, by pivoting together in the same direction, are able to follow a movement that is forced on a brake shoe due to local position deviations of the associated braking rail.
