Abstract: The invention concerns an valve drive assembly for a valve unit for regulating a flow of fluid with a lead-through of an operating rod (3) through a flange (4), particularly the arrangement of operating rod (3) to the flange (4) for adjusting a defined flow of fluid. The assembly comprises a flange (4), and operating rod (3) and an annular element. The operating rod (3) is disposed through said flange, and annular element is disposed between flange (4) and operating rod (3) defining an annular gap (12) between the annular element and the operating rod. An effective length of the annular gap (12) exceeds a thickness of the flange (4). This invention leads to considerable cost savings, as the component parts can now be produced more simply using manufacturing processes known from mass production, such as deep-drawing or even stamping.

Abstract: An electric motor driven valve for use in gas meters, has at least one valve unit (V) with a valve body and a valve element, a drive unit (A) and a connection unit (S). The units (V, A, S) can be connected to each other and separated from each other, in a modular manner. The valve element is a spherical or cylindrical valve element that is sealed relative to the valve body by means of only one sealing element, which is preferably a lip seal. The valve body has two recesses in which the valve element is rotatably mounted.

Abstract: A gas meter with integrated gas shut-off valve has a housing with a gas inlet and a gas outlet. A device to record the gas flow, a meter mechanism, a gas shut-off valve and optionally a pressure reducer are positioned in a gas flow path between the gas inlet and the gas outlet. The gas shut-off valve is an electrically operated valve with a spherical or cylindrical valve element.

Abstract: A fluid-tight cable bushing for a ribbon cable has two profile supports. The ribbon cable extends through an opening in a penetration element, such as a housing for a switch or meter. The bushing has two profile supports each with a first flange having snap-on elements and a second flange. The first flanges extend symmetrical along and enclose the ribbon cable. To form a first fixation point, the snap-on elements are v-shaped and arranged to snap against a first end of the opening. To form a second fixation point, the second flanges extend laterally beyond a second end of the opening. A fluid-tight potting mass covers one of the fixation points. Preferably, the potting mass is disposed in a recess formed in the penetration element about the opening.

Abstract: A multi-stage planetary gear train, with several annular segments arranged between the adapter plates of the motor and of the gear head, each annular segment has a planetary gear set comprising a sun gear, several planet gears carried by a planet carrier, and a ring gear having inner teeth. Adjacent annular segments are coupled to each other and the outer segments are coupled to the respective adapter plates. The annular segments and the corresponding adapter plates in the region of the adjacent end faces thereof form a coupling area each, and the segments each comprise at least one engaging element on one end face thereof and at least one complementary receiving element on the opposite end face thereof, wherein the engaging element of a segment engages with the receiving element of an adjacent segment or of an adapter plate in a form-fit or force-closed manner in the assembled state.
