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.
Claims13
A pneumatic valve device for use with a pneumatically operable device and a storage vessel for pressurized gas at a pressure to operate the pneumatically operable device comprising:
- a pneumatic valve pneumatically connectable to the storage vessel to admit and release pressurized gas into and from the storage vessel;
- connecting means for pneumatically connecting said pneumatic valve to the pneumatically operable device to conduct pressurized gas released through said pneumatic valve to the pneumatically operable device;
- and
- a manually operable control means operable to release pressurized gas from the pneumatic valve into the connecting means;
- said manually operable control means having a closed position covering the pneumatic valve and permitting the release of pressurized gas from the pneumatic valve into the connecting means and an open position not covering the pneumatic valve and permitting access to the pneumatic valve to refill the storage vessel by admitting gas through the pneumatic valve.
A pneumatic horn device for use with a storage vessel for pressurized gas comprising:
- a pneumatic horn;
- a pneumatic valve pneumatically connectable to the storage vessel to admit and release pressurized gas into and from the storage vessel;
- connecting moans pneumatically connecting said pneumatic valve to the pneumatic horn to operate the pneumatic horn;
- a manually operable control means operable to release pressurized gas from the pneumatic valve into the connecting means;
- and
- said manually operable control means having a closed position covering the pneumatic valve and permitting the release of pressurized gas from the pneumatic valve into the connecting means and an open position not covering the pneumatic valve and permitting access to the pneumatic valve to refill the storage vessel by admitting gas through the pneumatic valve.
A pneumatic spray device device comprising:
- a nozzle spray tube;
- a storage vessel for pressurized gas at a pressure to provide pressurized gas for the nozzle spray tube;
- a pneumatic valve pneumatically connected to the storage vessel to admit and release press gas into and from the storage vessel;
- connecting means pneumatically connecting said pneumatic valve to the nozzle spray tube to conduct pressurized gas released through said pnuematic valve to the nozzle spray tube horn to cause pressurized gas to be emitted from the nozzle spray tube;
- and
- a manually operable control means operable to release pressurized gas from the pneumatic valve into the connecting means;
- said manually operable control means having a closed position covering the pneumatic valve and permitting the release of pressurized gas from the pneumatic valve into the connecting means and an open position not covering the pneumatic valve and permitting access to the pneumatic valve to refill the storage vessel by admitting gas through the pneumatic valve.
