Rotatable Throttle Element for Sanitary Cistern Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for adjusting the flushing flow from a sanitary cistern are cumbersome and prone to errors, requiring multiple throttle rings with different diameters, which can be lost or difficult to set correctly, leading to unsatisfactory flow adjustments.
Innovation Solution
A device featuring a rotatable throttle element with latching steps and a rod-shaped handle, allowing for convenient adjustment of the flushing flow by changing the size of the free flow cross-section, eliminating the need for multiple throttle rings and providing a cost-effective solution for various settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple throttle rings with different diameters are used to adjust flushing flow, then the flushing flow can be throttled to different extents, but the adjustment process becomes complicated and the throttle rings can be lost
Solution Approach 1:
The invention replaces static throttle rings with a dynamic adjustable throttle element that can be rotated to different positions. The throttle element has an adjustable effective diameter that can be continuously changed by rotation, allowing the flushing flow to be adjusted dynamically without needing multiple separate components.
Solution Approach 2:
The single adjustable throttle element serves multiple functions: it can be adjusted to provide different levels of throttling (replacing multiple throttle rings), it can be easily set by rotation (improving ease of operation), and it remains in place permanently (preventing loss). This multi-functional design consolidates what previously required multiple separate components.
2Object-affected harmful factors
If throttle rings are inserted into the valve seat to reduce flow cross section, then the flushing flow is reduced, but the setting becomes complicated and uncomfortable
Solution Approach 1:
The throttle element provides dynamic adjustment capability where the effective flow cross-section can be continuously modified by rotating the element to different angular positions. This eliminates the need for complicated manual insertion and positioning of separate throttle rings, making the adjustment process simple and comfortable.
3Device complexity
If a single adjustable throttle is used instead of multiple throttle rings, then the device complexity is reduced and costs are lowered, but the mechanism for adjustment is needed
Solution Approach 1:
The adjustable throttle element incorporates a rotation mechanism that allows simple angular adjustment to change the effective flow area. This dynamic adjustment capability is achieved through a straightforward rotational motion that requires minimal operational complexity while providing versatile flow control.
Solution Approach 2:
The throttle element is designed with a segmented or profiled structure that creates different flow passages at different rotational positions. This segmentation allows a single component to provide multiple throttling settings through rotation, reducing device complexity while maintaining adjustment functionality.

AI summary
The invention relates to a device for throttling the flushing flow from a sanitary cistern (1), in particular a toilet cistern, which includes a flush valve (2) comprising a valve socket, a valve body (7) having a sealing surface or seal (9) which is movably mounted in the valve socket, a drain spout (5) and a valve seat (3) formed on the drain spout (5), wherein the sealing surface or seal (9) rests on the valve seat (3) in the closed state of the flush valve (2) and releases a drain opening defined by the drain spout (5) in the open state of the flush valve (2), with a throttle (4) which defines at least one free flow cross-section (6).In order to provide a device by means of which the flushing flow from a sanitary cistern (1) can be conveniently and reliably adjusted, it is proposed that the throttle (4) be arranged or can be arranged downstream of the valve seat (3) in the direction of the flushing flow at or in the outlet nozzle (5) of the flush valve (2) or in a connection nozzle receiving the outlet nozzle (5), wherein the throttle (4) has at least two throttle elements (4.1, 4.2), one of which is rotatable relative to another of the throttle elements (4.2), so that by rotating the rotatable throttle element (4.1) relative to the other throttle element (4.2) the size of the at least one free flow cross-section (6) can be changed.
