Title:
Valve drive assembly and valves used for it
Document Type and Number:
Japanese Patent JP6292803
Kind Code:
B2
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.
