Abstract
The present invention discloses an improved compressed air foam pumping/generation system in which the compressed gas that is used to drive a pumping system is re-utilized and introduced into the outlet manifold to more efficaciously generate a compressed gas foam. A further improvement could include a three-way valve which controls the flow of the compressed gas so that the present invention could be used to generate CAF, aspirated foam (with use of an appropriate nozzle), gels or operate as a simple pump. Additional optional components include a check valve and flexible connection material.
Claims24
An article of manufacture which comprises a pump that utilizes compressed gas to pump a fluid and generate a compressed gas foam comprising:
- a. a pump comprising at least one inlet, at least one outlet, an inlet chamber, an outlet chamber and a pumping means;
- b. said at least one fluid inlet is in fluid communication with the inlet chamber;
- the fluid outlet in fluid communication with the outlet chamber;
- c. said pumping means comprising a compressed gas inlet and a compressed gas outlet;
- said pumping means adapted to move fluid from the fluid inlet, through the inlet chamber to the outlet chamber and to the fluid outlet under pressure from said compressed gas;
- d. said three-way valve having one inlet and a first and a second outlet;
- e. said compressed gas outlet is in direct fluid communication with the input of said three-way valve;
- f. the first outlet of said three-way valve placed in direct fluid communication with the outlet chamber;
- and
- g. said three-way valve adapted to either direct the compressed gas to the outlet chamber
- to generate a compressed gas foam or alternatively direct the compressed gas to said second outlet.
An article of manufacture comprising a pump which utilizes compressed gas to pump a fluid and generate a compressed gas foam comprising:
- a. a pump comprising at least one inlet, at least one outlet, an inlet chamber, and an outlet chamber and a pumping means;
- b. said at least one fluid inlet is in fluid communication with the inlet chamber;
- the fluid outlet in fluid communication with the outlet chamber;
- c. said pumping means comprising a compressed gas inlet and a compressed gas outlet;
- said pumping means adapted to move fluid from the fluid inlet, through the inlet chamber to the outlet chamber and to the fluid outlet under pressure from said compressed gas;
- d. the outlet of said two-way valve further placed in direct fluid communication with the outlet chamber;
- and
- e. said two-way valve adapted to turn off the flow of exhaust gas through the two-way valve and thus halting operation of the pump.
An article of manufacture comprising a pump which utilizes compressed gas to pump a fluid and generate a compressed gas foam comprising:
- a. a pump comprising at least one inlet, at least one outlet, an inlet chamber, and an outlet chamber and a pumping means;
- b. said at least one fluid inlet is in fluid communication with the inlet chamber;
- the fluid outlet in fluid communication with the outlet chamber;
- c. said pumping means comprising a compressed gas inlet and a compressed gas outlet;
- said pumping means adapted to move fluid from the fluid inlet, through the inlet chamber to the outlet chamber and to the fluid outlet under pressure from said compressed gas;
- from the fluid inlet, through
- the inlet chamber to the outlet chamber and to the fluid outlet under pressure from
- said compressed gas;
- d. said compressed gas outlet is in direct fluid communication with the outlet chamber.
A kit comprising:
- a drill and tap adapted to form a female threaded opening in the outlet manifold of a gas driven pump;
- a length of tubing sized and bent to fit from the exhaust gas outlet of a gas-driven pump to the female threaded opening in the outlet manifold;
- a first adaptor to attach the first end of the length of tubing to the exhaust gas outlet of said pump;
- and
- a second adaptor to attach the second end of the length of tubing to the female threaded opening in the outlet manifold.
A kit comprising:
- a. the tools necessary to create a threaded hole in the outlet manifold;
- b. a length of connecting tubing;
- and
- c. a first pair of adapters to connect the tubing from the compressed gas outlet of the pump to the threaded hole made in the outlet manifold.
