Fluid moving device

Claim 2

A fluid moving device comprising a casing having a hollow interior, a fluid inlet communicating between the exterior and interior of the casing, a fluid outlet communicating between the interior and exterior of the casing at a location spaced from said inlet, a carrier mounted in said casing for movement about an endless path extending from said inlet to said outlet in one direction and extending from said outlet to said inlet in the other direction, at least a portion of said carrier being fabricated of resiliently compressible permeable material for movement about said path, and compressing means along said other direction of said path for compressing engagement with said carrier portion to expel fluid from said portion to said outlet, said portion expanding by elastic restoring force along said one direction of said path to absorb fluid and transfer the same to said outlet, said compressing means comprising a rotor in rolling engagement with said carrier for effecting said compressing.

Claim 3

A fluid moving device according to claim 1, said carrier comprising a rotor, and said portion comprising a peripheral portion of said rotor.

Claim 4

A fluid moving device according to claim 1, said internal casing hollow being specifically configured for conforming reception of said carrier, to minimize pressure loss along said path in said other direction.

Claim 5

A fluid moving device according to claim 1, said carrier comprising a generally circular rotor, and said casing interior conformably receiving said rotor to minimize loss of pressure in said casing.

Claim 6

A fluid moving device comprising a casing having a hollow interior, a fluid inlet communicating between the exterior and interior of the casing, a fluid outlet communicating between the interior and exterior of the casing at a location spaced from said inlet, a carrier mounted in said casing for movement about an endless path extending from said inlet to said outlet in one direction and extending from said outlet to said inlet in the other direction, at least a portion of said carrier being fabricated of resiliently compressible permeable material for movement about said path, and compressing means along said other direction of said path for compressing engagement with said carrier portion to expel fluid from said portion to said outlet, said portion expanding by elastic restoring force along said one direction of said path to absorb fluid and transfer the same to said outlet, said compressing means comprising a second carrier mounted in said casing for movement about an endless path extending from said inlet to said outlet in said one direction and extending from said outlet to said inlet in the other direction, at least a portion of said second carrier being fabricated of resiliently compressible permeable material for movement about said path, said first and second carriers being in compressing engagement with each other to mutually expel fluids from said portions to said outlet, said portions expending by elastic restoring forces along said one directions of said paths to absorb fluid and transfer the same toward said outlet.

Claim 7

A fluid moving device comprising a casing having a hollow interior, a fluid inlet communicating between the exterior and interior of the casing, a fluid outlet communicating between the interior and exterior of the casing at a location spaced from said inlet, a carrier mounted in said casing for movement about an endless path extending from said inlet to said outlet in one direction and extending from said outlet to said inlet in the other direction, at least a portion of said carrier being fabricated of resiliently compressible permeable material for movement about said path, and compressing means along said other direction of said path for compressing engagement with said carrier portion to expel fluid from said portion to said outlet, said portion expanding by elastic restoring force along said one direction of said path to absorb fluid and transfer the same to said outlet, said compressing means comprising a second carrier mounted in said casing for movement about an endless path extending from said inlet to said outlet in said one direction and extending from said outlet to said inlet in the other direction, at least a portion of said second carrier being fabricated of resiliently compressible permeable material for movement about said path, said first and second carriers being in compressing engagement with each other to mutually expel fluids from said portions to said outlet, said portions expending by elastic restoring forces along said one directions of said paths to absorb fluid and transfer the same toward said outlet.

Claim 8

A fluid moving device comprising a casing having a hollow interior, a fluid inlet communicating between the exterior and interior of the casing, a fluid outlet communicating between the interior and exterior of the casing at a location spaced from said inlet, a carrier mounted in said casing for movement about an endless path extending from said inlet to said outlet in one direction and extending from said outlet to said inlet in the other direction, at least a portion of said carrier being fabricated of resiliently compressible permeable material for movement about said path, and compressing means along said other direction of said path for compressing engagement with said carrier portion to expel fluid from said portion to said outlet, said portion expanding by elastic restoring force along said one direction of said path to absorb fluid and transfer the same to said outlet, said carrier comprising a generally circular rotor, and said casing interior conformably receiving said rotor to minimize loss of pressure in said casing, said compressing means comprising a second circular rotary carrier mounted in said casing for movement about an endless path extending from said inlet to said outlet in one direction and extending from said outlet to said inlet in the other direction, at least a portion of said second carrier being fabricated of resiliently compressible permeable material for movement about said path, said first and second carriers being in compressing engagement with each other to mutually expel fluid from said portions to said outlet.

Claim 9

A fluid moving device comprising a casing having a hollow interior, a fluid inlet communicating between the exterior and interior of the casing, a fluid outlet communicating between the interior and exterior of the casing at a location spaced from said inlet, a carrier mounted in said casing for movement about an endless path extending from said inlet to said outlet in one direction and extending from said outlet to said inlet in the other direction, at least a portion of said carrier being fabricated of resiliently compressible permeable material for movement about said path, and compressing means along said other direction of said path for compressing engagement with said carrier portion to expel fluid from said portion to said outlet, said portion expanding by elastic restoring force along said one direction of said path to absorb fluid and transfer the same to said outlet, said carrier comprising a generally circular rotor, and said casing interior conformably receiving said rotor to minimize loss of pressure in said casing, said compressing means comprising a second circular rotary carrier mounted in said casing for movement about an endless path extending from said inlet to said outlet in one direction and extending from said outlet to said inlet in the other direction, at least a portion of said second carrier being fabricated of resiliently compressible permeable material for movement about said path, said first and second carriers being in compressing engagement with each other to mutually expel fluid from said portions to said outlet.
