## Abstract

A valve assembly, includes a first lumen; a second lumen providing fluid communication between a plurality of points in said first lumen; and a ball and spring assembly sealingly disposed in said first lumen between said plurality of points, wherein said spring exerts a force on said ball to seal said first lumen; wherein said valve assembly is configured to oscillate a pressure of a fluid passing through said valve assembly.

## Claims

### Claim 1

A valve assembly, comprising:
a first lumen;
a second lumen providing fluid communication between a plurality of points in said first lumen; and
a ball and spring assembly sealingly disposed in said first lumen between said plurality of points, wherein said ball has a first sealing position and a second sealing position;
wherein said spring exerts a force on said ball to selectively seal said first lumen in said first sealing position;
wherein said valve assembly is configured to oscillate a pressure of a fluid passing through said valve assembly.

### Claim 2 (depends on 1)

The valve assembly of claim 1, further comprising a volume regulator disposed in said second lumen; wherein said volume regulator is configured to vary a fluid pressure exerted on said ball.

### Claim 3 (depends on 2)

The valve assembly of claim 2, wherein said volume regulator comprises a needle valve configured to regulate a fluid flow through said second lumen.

### Claim 4 (depends on 1)

The valve assembly of claim 1, further comprising a trigger valve fluidly coupled to an inlet of said first lumen;
wherein said trigger valve is configured to selectively control a flow of liquids into said valve assembly.

### Claim 5 (depends on 4)

The valve assembly of claim 4, wherein said trigger valve is actuated by a lever.

### Claim 6 (depends on 1)

The valve assembly of claim 1, wherein said first lumen and said second lumen are both formed in a single valve body.
