French horn with valves in line - has lowermost valve forming water drain with detachable collector vessel below when turned from working position

摘要

The horn contains straight sections of tube and bends, while the valves (20,22,24) are interconnected. When the horn is turned from the working position into a second one, they are in a line sloping or extending vertically upwards.In this position, the lowermost valve (26) forms a drain for condensed water, below which is a removable water collecting vessel (34). In this position all the tubes leading to the valves slope downwards. Where the horn is a duplex one, the change-over valve can act as a drain valve, having an additional outlet (33) for each valve level,to which the vessel is connected. The vessel can consist of a tube bend which can be pulled off. ADVANTAGE - Simple central drainage of condensate.
