Abstract
In order to achieve high opening speeds in a dry running gas valve with electromagnetic actuation, it is provided to arrange the engagement point of the magnet armature 22 and the limit stop at the radially inner guide region 16 of the valve element 2. Due to the resulting reduced deflection, the valve element can be built more compact and lighter and the residual air gap can be reduced, which allows higher opening speeds.
Claims12
A dry running gas valve having a disk-shaped valve element (2) with a number of throughflow channels which valve element interacts sealingly with a valve seat (10), wherein the valve element (2) is connected to a magnet armature (22) which interacts with an electromagnet (5) arranged in the gas valve (1), wherein the valve element (2) is arranged such that it is mounted radially on the inside in guided manner by providing radially on the inside of the valve element (2) a guide region (16) with a central recess (18), the inner circumferential surface of which forms a guide surface and the valve element (2) is slid with the central recess (18) onto a guide pin (4) centrally arranged in the gas valve (1) and is mounted on the guide pin (4) in an axially displaceable and guided manner, that the magnet armature (22) is connected at the guide region (16) to the valve element (2) and in the gas valve (1), a limit stop for the valve element (2) is provided which limit stop interacts with the guide region (16).
