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