In addition advantageously, if this common driving pipe element has second acceptance division, this second acceptance division comprise valve seat, with the coefficient valve body of valve seat and act on the valve spring on the valve body avoid external action because valve spring is provided with protection with this mode.
Very advantageously be, have input channel and at least one output channel if drive pipe element, wherein, input channel is led in the pressure regulator valve and to the flow that becomes a mandarin of at least one output channel and is regulated by pressure regulator valve.
Also advantageously, at the guiding rib of having constructed on the output channel on the through hole that is used to be supported on lid, because realize that by this way assembling drives pipe element simply.
Description of drawings
Embodiments of the invention illustrate simplifiedly in the accompanying drawings and specification below at length explain.Accompanying drawing illustrates:
Fig. 1 illustrates the device that is used for transfer the fuel that has according to first embodiment's driving pipe element with sectional view,
Fig. 2 is according to second embodiment's driving pipe element.
Embodiment
Fig. 1 illustrates the device that is used for transfer the fuel that has according to first embodiment's driving pipe element with sectional view.
The device that is used for transfer the fuel is arranged on fuel tank 1 and by the for example electric petrolift that moves of conveying unit 2 fuel is delivered to internal-combustion engine 4 through pressure piping 3 from fuel tank 1 pressure with raising.
Carry unit 2 to be arranged in the reservoir vessel 5, this reservoir vessel has been kept enough fuel for carrying unit 2, even but should carry unit under the situation of fuel tank 1 low occupid state and quickening, braking, turning and/or suction of fuel during climbing thus.
Tell driving pipeline 8 from the pressure piping 3 of this device, this driving pipeline drives the suction jet pump 9 that is used for initiatively filling reservoir vessel 5.This driving pipeline 8 can also perhaps otherwise be supplied with fuel by the backflow portion that does not illustrate of internal-combustion engine 4 apparently.This driving pipeline 8 leads in the suction chamber 11 of suction jet pump 9 through the beam carry-out part 10 of the constituted nozzle that for example narrows down.Mixing is led to 12 and is connected on the suction chamber 11.The mode of action of suction jet pump 9 is open by fully, makes and describes here only shortly: through driving pipeline 8 and its jet carry-out part 10, import in the suction chamber 11 with driving stream beam shape.The driving beam that drives pipeline 8 is carried to fuel on every side the hybrid channel 12 from suction chamber 11, makes surveying flow pass through hybrid channel 12 and arrives in the reservoir vessels 5.In suction chamber 11, have negative pressure, this negative pressure adds to fuel the suction chamber 11 from fuel tank 1 through the suction bole 15 of suction chamber 11.
In driving pipeline 8, pressure regulator valve 16 is set, just opens driving pipeline 8 and move suction jet pump 9 thus in the time of on the pressure of confirming in advance of this pressure regulator valve in pressure piping 3.Guarantee when cranking internal combustion engine 4 build-up pressure apace by this way.
Propose according to the present invention; In driving pipeline 8, control valve 17 is set in the downstream of pressure regulator valve 16; This control valve will drive pressure limit in the pipeline 8 on the maximum value of confirming in advance, and wherein, pressure regulator valve 16 is arranged on the common driving pipe element 18 with control valve 17.This driving pipe element 18 is embodied as compact and building blocks of function that cost is favourable with this mode.
This common driving pipe element 18 has first acceptance division 19, but in this acceptance division assembling pressure modulating valve 16.For example this pressure regulator valve 16 is encased in first acceptance division 19 as independent member, and this pressure regulator valve mechanically with hydraulically is connected with driving pipe element 18 with fixed element by sealing in this pressure regulator valve.Alternatively, for example can valve 16 be integrated in the driving pipe element 18, making does not need separate casing and realizes going back the favourable driving pipe element of cost thus for pressure regulator valve 16 yet.
In addition, this common driving pipe element 18 has second acceptance division 20, this second acceptance division comprise control valve 17 valve seat 21, with valve seat 21 coefficient valve bodies 22 and act on valve spring 23 on the valve body 22, control valve 17.According to this embodiment, valve body 22 is that spheroid and valve spring 23 are leaf springs.These acceptance division 20 protection valve bodies 22 avoid the external force effect with valve spring 23.
This driving pipe element 18 has input channel 26 and at least one transfer passage 27, and wherein, input channel 26 is led in the input part of pressure regulator valve 16 and wherein, to the flow that becomes a mandarin of at least one output channel 27 by pressure regulator valve 16 adjustings.The input channel 26 that drives pipe element 18 is the parts that drive pipeline 8 with at least one output channel 27.
Be used to be supported on the rib 28 that covers on 30 the through hole 29 having constructed on the output channel 27, this lid is arranged on the reservoir vessel 5.
