Abstract
A valve unit is provided which has a housing with a cover. Accommodated in the housing is a valve drive which is connected to a valve spindle. A closing body is arranged at an end of the valve drive opposite to the valve spindle. Furthermore, an elastic element is arranged between a contact face in the housing facing away from the closing body and the valve drive, so that the elastic element pretensions the valve drive toward the cover in a closed state of the valve unit. Such a configuration of the valve unit allows the accommodation of a valve unit in a housing to be simplified. Furthermore, the tolerances, for example the manufacturing tolerances of the housing, are compensated for by the pretensioning of the valve drive by the elastic element.
Claims16
A valve unit-comprising a housing having a cover, a valve drive that is connected to a valve spindle, a closing body that is arranged at an end of the valve spindle opposite to the valve drive, and an elastic element that is arranged between a contact face in the housing facing away from the closing body and the valve drive;
- wherein the elastic element pretensions the valve drive toward the cover in a closed state of the valve unit.
A method of manufacturing a valve unit, wherein the method comprises steps of:
- preassembling a drive assembly having a valve drive;
- preassembling a housing assembly having a housing with an open side;
- placing the drive assembly on a cover or closing the housing, wherein an elastic element is placed on the valve drive during preassembling or after placing the drive assembly on the cover;
- placing the housing with its open side first on the drive assembly while compressing the elastic element;
- applying a force so that the elastic element is compressed and the valve drive presses against the elastic element;
- and fastening the housing to the cover.
