Abstract
Provided is a flexible hose assembly having an inner nipple coupled to an inner flexible hose and an outer nipple at least partially surrounding the inner nipple and being coupled to an outer flexible hose, wherein a first fluid flowing through the inner nipple is directed outward in-between the inner and outer flexible hoses and a second fluid flowing in-between the inner and outer nipples is directed inward to the inner flexible hose. By directing the second fluid inward and the first flow outward, the outer flexible hose is prevented from collapsing on the inner flexible hose when pressure of the second fluid flowing through the inner flexible hose is greater than a pressure of the first fluid flowing through the outer flexible hose.
