Abstract
A compressor pump for conveying fluids is provided and consists of an electric motor driving a cone-shaped impeller within a stationary casing affixed to a stationary stand in which fluids entering the casing and through the impeller are compressed to exit therefrom into a hose affixed to the stand for carrying the compressed fluids.
Claims3
A compressor pump for conveying fluids which comprises:
- (a) an electric motor having a drive shaft;
- (b) a stationary casing having an operating chamber and an inlet port;
- (c) a cone-shaped impeller having a wide inlet configuration with shaft and a narrow outlet configuration, the shaft coupled to the drive shaft of said motor so as to be rotatably mounted within the operating chamber of said casing in which fluids entering said casing and through said impeller are compressed to exit therefrom;
- (d) a stationary stand having a bearing sleeve affixed to said casing and the narrow outlet configuration of said impeller;
- (e) a hose affixed to said stand for carrying the compressed fluids from the narrow outlet configuration of said impeller, wherein said impeller comprises:
- (a) an inner cone-shaped hub;
- (b) an outer cone-shaped sleeve;
- (c) a pair of helix-shaped blades encircling said hub within said sleeve, each of said blades at an angle which is in the range of 20.degree. to 70.degree. at the wide inlet configuration, further comprising:
- (a) an outer fluid deflector affixed around outside of the inlet port of said casing;
- (b) at least one flutter valve mounted to said casing opposite said outer fluid deflector;
- and
- (c) An inner fluid deflector mounted to said outer cone-shaped sleeve adjacent said outer fluid deflector so as to prevent fluid pressure buildup within the operating chamber of said casing.

- (a) an inner cone-shaped hub;
- (b) an outer cone-shaped sleeve;
- and
- (c) a pair of helix-shaped blades encircling said hub within said sleeve, each of said blades at an angle which is in the range of 20.degree. to 70.degree. at the wide inlet configuration, further comprising:
- (a) a conduit extending tangently from one side of the inlet port of said casing for carrying the fluids into said casing;
- and
- (b) a check valve mounted within said conduit to prevent fluid back pressure build up within the operating chamber of said casing.
