Abstract

Fluid flow control valves are provided having a jet pump or aspirator connected to a plurality of fluid passageways. Fluid flow from one of the passageways through the jet pump creates a partial vacuum enabling fluid flow to be drawn through the other of the fluid passageways connected to the jet pump. Such valves enable hydraulic fluids of a single-acting piston-cylinder unit or the like to be readily exhausted.
