Abstract
This invention relates to a pneumatic valve device, such as a pneumatic horn and a pneumatic sprayer, which is operable by pressurized gas from a storage vessel. It comprises a valve pneumatically connectable to the storage vessel to admit and release pressurized gas into and from the storage vessel; a connecting chamber for pneumatically connecting the valve to the pneumatically operable device to conduct pressurized gas released through the valve to the pneumatically operable device; and a manually operable control operable to release pressurized gas from the valve into the connecting chamber.
