FLUID CONTROL VALVE ASSEMBLY

WIPO Patent Application WO/2013/011366

A8

A valve assembly (34) includes a housing defining first (44), second (46), third (48), and fourth (50) passages. The first passage (44) channels relatively-high pressure fluid and the second passage (46) channels relatively-low pressure fluid into the valve. The third passage (48) connects to the second passage (46) and releases fluid from the valve. The fourth passage (50) connects to the first passage (44) and the second passage (46) and releases fluid from the valve. The valve assembly also includes a first check-valve (52) that permits fluid flow from the second passage (46) to the third passage (48) and a second check-valve (54) that permits fluid flow from the second passage (46) to the fourth passage (50). The valve assembly additionally includes a nozzle (60) that controls velocity of the relatively-high pressure fluid entering the fourth passage (50) from the first passage (44). The relatively-low pressure fluid is pulled from the second passage (46) into the fourth passage (50) on the outer periphery (62) of the nozzle (60) by the relatively-high pressure fluid.
