摘要： A combined pressure regulator and jet pump includes a valve member and cooperating nozzle defining member which are coaxial and independently movable. Both members are responsive to the difference in upstream and downstream pressures and each member will move relative to the other in response to a predetermined pressure difference. The relative movement between the nozzle defining and valve members will not interrupt the pumping action resulting from fluid flow through the variable area nozzle formed by these members.
