A novel three-way valve comprising a valve body, a valve sleeve for adjustable position mounting within the body, and a valve stem movable so as to selectively form a pathway between line recesses in the valve sleeve. Three line recesses are used to form a three way valve and the front and rear line recesses are provided around the diameter such that an increased number of apertures may be provided while reducing the diameter of the apertures themselves to provided the necessary fluid flow with a reduced throw requirement for the valve stem. Exhaust valves are provided to relieve pressure on the unused fluid path. Preferably, the apertures are equi-spaced around the recesses diameter to create a more efficient fluid flow. The valve has a knob and/or a hex key for making fine adjustments to the position of the valve sleeve for optimal efficiency.

What is claimed is: 1. A valve apparatus, comprising: an external body defining an internal cavity with a first capturing element, the external body further defining at least a first fluid connection, a second fluid connection, and a third fluid connection; a single body internal valve sleeve adapted to sealably engage the internal sleeve cavity to an adjustable depth by using a second sleeve capturing element adapted to engage the first sleeve capturing element, the depth of the internal valve sleeve adapted to be adjusted by a force external to the external body, the internal valve sleeve defining a first sealed chamber having a first aperture set flowably connected to the first fluid connection, a second sealed chamber having a second aperture set flowably connected to the second fluid connection, and a third sealed chamber having a third aperture set flowably connected to the third fluid connection; the internal valve sleeve further defining an internal stem bore with at least a first unsealed end forming a first exhaust port; a valve stem including a sealed section, the valve stem adapted to sealably move within the internal stem bore to alternatively provide a first flow path from the first aperture set to the second aperture set or provide a second flow path from the second aperture set to the third aperture set; and, at least one seal adapted to sealably contact the valve stem and the internal stem bore, the seal adapted to sealably move within the internal stem bore. 2. The apparatus of claim 1, wherein the first sleeve capturing element and the second sleeve capturing element are controllably engagable to adjust the depth of the internal valve sleeve in the eternal body. 3. The apparatus of claim 1, wherein the first sleeve capturing element and the second sleeve capturing element are mating threads. 4. The apparatus of claim 1, the sleeve further defining external frictional knurling. 5. The apparatus of claim 1, the sleeve further defining a tool engagement aperture. 6. The apparatus of claim 5, the tool engagement aperture comprising a hex wrench socket. 7. The apparatus of claim 1, the first aperture set including at least one aperture with a first diameter and the second aperture set having at least one aperture with a second diameter wherein the first diameter is smaller than the second diameter. 8. The apparatus of claim 1, the first aperture set including multiple apertures diametrically positioned around the internal valve sleeve. 9. The apparatus of claim 1, the second aperture set including multiple apertures diametrically positioned around the internal valve sleeve. 10. The apparatus of claim 1, the second aperture set including at least one aperture with a second diameter and the third aperture set having at least one aperture with a third diameter wherein the second diameter is larger than the third diameter. 11. The apparatus of claim 1, the third aperture set including multiple apertures diametrically positioned around the internal valve sleeve. 12. A valve apparatus, comprising: an external body defining an internal cavity with a first capturing element, the external body further defining at least a first fluid connection, a second fluid connection, and a third fluid connection; a single body internal valve sleeve adapted to sealably engage the internal sleeve cavity to an adjustable depth by using a second sleeve capturing element adapted to engage the first sleeve capturing element, the depth of the internal valve sleeve adapted to be adjusted by a force external to the external body, the internal valve sleeve defining a first sealed chamber having a first aperture set flowably connected to the first fluid connection, a second sealed chamber having a second aperture set flowably connected to the second fluid connection, and a third sealed chamber having a third aperture set flowably connected to the third fluid connection, the internal valve sleeve further defining an internal stem bore with at least a first unsealed end forming a first exhaust port; a valve stem adapted to sealably move within the internal stem bore to alternatively provide a flow path from the first aperture set to the second aperture set or provide a flow path from the first aperture set to the first exhaust port; and at least one seal adapted to sealably contact the valve stem and the internal stem bore, the seal adapted to sealably move within the internal stem bore. 13. The apparatus of claim 12, wherein the first sleeve capturing element and the second sleeve capturing element are controllably engagable to adjust the depth of the internal valve sleeve in the external body. 14. The apparatus of claim 12, the sleeve further defining external frictional knurling. 15. The apparatus of claim 12, the sleeve further defining a tool engagement aperture. 16. The apparatus of claim 12, the first aperture set including at least one aperture with a first diameter and the second aperture set having at least one aperture with a second diameter wherein the first diameter is smaller than the second diameter. 17. The apparatus of claim 12, the internal valve further defining a second unsealed end forming a second exhaust port wherein when the valve stem provides for a flow path from the second aperture set to the first aperture set the valve stem is adapted to provide a flow path from the third aperture set to the second exhaust port. 18. A valve apparatus, comprising: an external body defining, an internal cavity with a first capturing element, the external body further defining at least a first fluid connection, a second fluid connection, and a third fluid connection; a single body internal valve sleeve adapted to sealably engage the internal sleeve cavity to an adjustable depth by using a second sleeve capturing element adapted to engage the first sleeve capturing element, the internal valve sleeve defining a first sealed chamber having a first aperture set flowably connected to the first fluid connection, a second sealed chamber having a second aperture set flowably connected to the second fluid connection, and a third sealed chamber having a third aperture set flowably connected to the third fluid connection; the internal valve sleeve further defining an internal stem bore with at least a first unsealed end forming a first exhaust port; a valve stem including a healed section, the valve stem adapted to sealably move within the internal stem bore to alternatively provide a first flow path from the first aperture set to the second aperture set or provide a second flow path from the second aperture set to the third aperture set; and, at least one seal adapted to sealably contact the valve stein and the internal stem bore, the seal adapted to sealably move within the internal stem bore. 19.
