An apparatus for storing, rotating and feeding a high pressure hose, including: a first rotatable drum with a helical groove; a second rotatable drum; and at least one actuator for rotating the first and second drums. For rotation of the first and second drums in first and second opposite directions, respectively, a hose and a cable are coilable into the helical groove such that the hose is in compressive engagement with the cable and the first drum. For rotation of the first and second drums in the second and first directions, respectively, the hose is uncoilable from the first drum and displaceable beyond the apparatus and the cable is coilable about the second drum.

A method for storing, rotating and feeding a high pressure hose, comprising: rotating, using at least one actuator for an apparatus, a first drum for the apparatus in a first rotational direction to coil the high pressure hose and a cable in a helical groove for the first drum;rotating, using the at least one actuator, a second drum for the apparatus in a second rotational direction, opposite the first rotational direction, to uncoil the cable from the second drum;compressively engaging the hose, the cable, and the helical groove, wherein the cable presses the hose radially inward to retain the hose in the groove;rotating, using the at least one actuator, the first drum in the second rotational direction to uncoil the high pressure hose and the cable from the helical groove and displace the high pressure hose from the first drum; and,rotating, using the at least one actuator, the second drum in the first rotational direction to coil the cable about the second drum. 2. The method of claim 1, wherein: the apparatus includes a housing and an outlet element;the first and second rotatable drums are disposed within the housing;rotating the first and second drums in the first and second directions, respectively, includes uncoiling a first portion of the cable from the second drum;compressively engaging the hose, the cable, and the helical groove includes urging, with the cable, the hose into a compressive engagement with a radially disposed portion of the helical groove;rotating the first and second drums in the second and first directions, respectively, includes uncoiling a second portion of the cable from the first drum; and,displacing the high pressure hose from the first drum includes displacing the hose through the outlet element. 3. The method of claim 2, wherein: the first drum is displaceable with respect to the outlet element; and,the first drum is displaceable along an axis of rotation for the first drum such that a portion of the helical groove, from which the hose is being uncoiled or into which the hose is being coiled, is aligned with the outlet element. 4. The method of claim 2, wherein: the outlet element is displaceable with respect to the first drum; and,the outlet element is displaceable along an axis of rotation for the first drum such that the outlet element is aligned with a portion of the helical groove from which the hose is being uncoiled or into which the hose is being coiled. 5. The method of claim 2, wherein the apparatus further comprises a displacement component engaged with the outlet element, the method further comprising rotating the displacement component with the at least one actuator such that: the outlet element displaces along an axis of rotation for the threaded rod in response to rotation of the displacement component; or,the threaded rod displaces with respect to the outlet element in response to rotation of the displacement component. 6. The method of claim 5, wherein the displacement component includes a threaded rod, the method further comprising: rotating the threaded rod in a third rotational direction such that: the first drum rotates in the first rotational direction and displaces in a first axial direction; or,the first drum rotates in the first rotational direction and the outlet displaces in a second axial direction, opposite the first axial direction; and,rotating the threaded rod in a fourth rotational direction, opposite the third rotational direction such that: the first drum rotates in the second rotational direction and displaces in the second axial direction; or,the first drum rotates in the second rotational direction and the outlet element displaces in the first axial direction. 7. The method of claim 1, wherein coiling a cable in the helical groove such that the hose is in compressive engagement with the helical groove includes exerting, with the cable, a pressure on the hose in a radially inward direction. 8. The method of claim 1, further comprising connecting a first end of the cable to the first drum and a second end of the cable to the second drum. 9. A method for storing, rotating and feeding a high pressure hose, comprising: rotating, using at least one actuator for an apparatus, a first drum for the apparatus in a first rotational direction to coil the high pressure hose and a cable in a helical groove for the first drum such that the cable presses radially inward on the hose and thereby places the hose in compressive engagement with the first drum;rotating, using the at least one actuator, a second drum for the apparatus in a second rotational direction, opposite the first rotational direction, to uncoil the cable from the second drum;rotating, using the at least one actuator, the first drum in the second rotational direction to uncoil the high pressure hose and cable from the helical groove and displace the high pressure hose through an outlet element for the apparatus;rotating, using the at least one actuator, the second drum in the first rotational direction to coil the cable about the second drum; and,rotating, with the actuator, a threaded rod engaged with the outlet element such that the outlet element is aligned with a portion of the helical groove from which the hose is uncoiling or into which the hose is coiling.
