Automatic deodorising spray unit for rubbish chutes etc. - supplied in box with external saddle for easy mounting on walls

摘要

An installation for injecting a spray of deodorising liq. into an enclosed space such as a rubbish chute. The installation is a box which houses a container of deodorising liq. under pressure. The container has a valve which is opened periodically by an automatic timer in order to pass liq. to a spray nozzle directed into the enclosed space. The box has an exterior saddle which can be secured to the outer wall of the enclosed space. A tubular bush extends through the wall of the box and through the saddle to provide a passage for the spray nozzle. The saddle is fixed to the wall of the enclosed space so that the bush is located to project into a hole through that wall. The nozzle outlet reaches into the wall space but does not project into the enclosed space.
