Abstract
A method and apparatus advantageously using the shapeless and flowing characteristics of a fluid. The fluid is contained with a suitable film chamber having a given shape; a frame or the like may be used as a supporting means for the chamber. The frame-shaped sack is repeatedly filled and exhausted with a fluid; upon being filled with fluid, it is inflated; upon the fluid therein being exhausted, it becomes deflated. A hollow chamber is supported with a film sack by repeatedly filling and exhausting fluid therefrom so as to have the hollow sack inflated and compressed. By using this method, the hollow sack is used as a pump for pumping a fluid therefrom.
Claims5
A pump composed of a flexible film consisting of a pumping chamber having a one-way valved intake port and a one-way valved exhaust port, a surrounding supporting chamber composed of a pipe network, said network having a combination intake/exhaust inlet, upon said supporting chamber being filled through said inlet with a first fluid, said pumping chamber expands, being supported by said support chamber, to absorb a second fluid through said intake port, and upon collapsing said support chamber by forcibly removing the fluid therefrom said pumping chamber discharges the fluid therein through said exhaust port, after which said pump is ready for the next cycle.
A pump composed of a flexible film consisting essentially of a pumping chamber having a one-way valved intake port and a one-way valved exhaust port, a surrounding supporting chamber having a combination intake/exhaust inlet, said respective chambers spaced apart by a plurality of interconnecting spacing films having openings therein whereby upon said supporting chamber being filled through said inlet with a first fluid, said pumping chamber expands, being supported by said surrounding support chamber, to absorb a second fluid through said intake port, and upon collapsing said support chamber by forcibly removing the fluid therefrom said pumping chamber discharges the fluid therein through said exhaust port, after which said pump is ready for the next cycle.
A pumping apparatus comprising:
- a first pump, composed of a flexible film, having:
- a pumping chamber for containing a fluid with a one-way valved intake port and a one-way valved exhaust port, a surrounding supporting chamber having a combination intake/exhaust inlet, said respective chambers spaced apart by a plurality of interconnecting spacing films having openings therein;
- a second pump, composed of a flexible film, having:
- a pumping chamber for containing a fluid with a one-way valved intake port and a one-way valved exhaust port, a surrounding supporting chamber having a combination intake/exhaust inlet, said respective chambers spaced apart by a plurality of interconnecting spacing films having openings therein;
- a hose extending between said first pump and said second pump and communicating with each supporting chamber of each respective pump, said hose having a closable aperture, therein;
- and
- an exhaust hose having a hose exhaust port therein, a pair of hose branches, said exhaust hose connected to a respective hose branch communicating between a pumping chamber of each said pump and said hose exhaust port, each said hose branch having a one-way valve therein for permitting only exhaustion of a fluid from a respective pump chamber through said hose exhaust port.
