摘要： A fuel control device 220 includes a restriction 294 and a check valve 292 disposed between a fuel return conduit 236 and a fuel injection supply conduit 227. In operation, fuel from tank 202 flows into the control device via conduit 208 is filtered through filter 222 flowing to an injection pump 230 outlet conduit 228. Excess fuel is returned to the control device and is then directed either back to the tank 202 via conduit 234 or is mixed with incoming fuel via conduit 235 and a two-position temperature responsive diverter valve 290. The restriction and check valve provide the benefit of allowing a continuous air bleed to purge any incoming air or vapor from the fuel supply system back to the fuel tank 202, while preventing unfiltered fuel flow from the fuel return outlet port to the filtered fuel outlet port.

摘要： An automotive vehicle fluid jet pump 7 is provided including a first chamber 340 having a rear end 348 sealed from a front end 344 by a pressure communicative boundary 352. The first chamber front end 344 has an inlet 332 fluidly connected with a source of pressurized fluid. The first chamber front end 344 also has a nozzled outlet 372. A second chamber 376 is provided having a first inlet fluidly connected with the first chamber outlet 372. The second chamber 376 has a second inlet 380 fluidly connected with a sump. The second chamber has a delivery outlet 334. A valve member 400 is operatively associated with the first chamber boundary 352 for controlling a flow from the first chamber inlet 332 through said first chamber outlet 372. A position of the valve member 400 with respect to said first chamber outlet 372 is responsive to a pressure differential between the first chamber front end 344 and rear end 348.
