Fig. 4 be according to pump group of the present invention from the time planimetric map; And
Fig. 5 is the sectional plan view when seeing from above according to pump group of the present invention.
Embodiment
Referring to each accompanying drawing, show a kind ofly according to petrolift group 1 of the present invention, described petrolift group 1 is used for the fuel supply system of 4 stroke jet engines.
As what can see in Fig. 1, pump group 1 is mechanical, and according to a preferred embodiment, it is installed in power unit 100 places, especially is installed on the head 51 of power unit itself.
In addition according to the preferred embodiment shown in Fig. 1-5, pump group 1 has a packing body made from die casting (containment body) 50, a mechanical feed pump 2, a sparger 8 and a pressure regulator 6, above-mentioned sparger 8 is positioned at the inside of a relative shell 4, and above-mentioned pressure regulator 6 is positioned at the inside of relative shell 5.
Pump 2 and sparger 8 are placed into by a connecting duct 7 and are communicated with, and above-mentioned connecting duct 7 is a supporting member 9 inner formation, and described supporting member 9 is used for sparger is screwed to packing body 50.As mentioned above, packing body 50 is directly installed on the head 51 of power unit 100.
In detail, packing body 50 is to utilize some screws 52 to be installed on the head 51 of power unit 100, simultaneously an adiabatic collector 10 is placed between the head 51 and packing body 50 of power unit 100.
As in Fig. 1, finding out better, pump 2 is taked to force control system 11 reciprocating from one, above-mentioned pressure control system 11 forms by an eccentric 12 with by a wishbone 13, above-mentioned eccentric 12 is installed on the camshaft of motor, and above-mentioned wishbone 13 engages with eccentric 12, will illustrate as following.
Wishbone 13 also as appreciable in each accompanying drawing, installs on the head 51 of power unit 100 by a rotary pivot of suitable clamping screw at 14 places.
Pump 2 comprises 15 groups in a cylinder 16-piston, and wherein piston 15 is driven by an axle 18, and axle 18 is driven by wishbone 13.
In detail, wishbone 13 has an extension, and described extension leans against in axle 18 the substrate, so as to give axle 18, and the stroke of therefore giving piston 15 with respect to cylinder 16 guiding.Contact between axle 18 and the wishbone 13 guarantees as a helical spring 19 by suitable elastic device.
The lubrication of coupling guarantees that by a suitable oil circuit oil that described oil circuit will pressurize is sent in the trunnion 17 between cylinder 16 and the piston 15, and trunnion 17 forms at the lower part of cylinder 16.
As what can be more clearly visible in Fig. 3, pump 2 also is included in a conveying chamber 28 at top place, and described conveying chamber 28 is connected on the connecting duct 7 at the place, top, and on the place, bottom is connected to 15 groups in cylinder 16-piston.
Pass connecting duct 7, conveying chamber 28 is placed into sparger 8 is communicated with.
Especially, between 15 groups in cylinder 16-piston and conveying chamber 28, an automatic cylindrical shape valve 40 is installed.This valve is made by a standing part 26 and a movable part 25.
Valve 40 and especially its movable part 25 can rise under the effect of piston 15, so that fuel is flow in the conveying chamber 28 by suitable hole 33, and flow to sparger 8 from here.
The quantity in hole 33, position and configuration can wish that the delivery profile that obtains changes according to people.
During the downward stroke of piston 15, suitable elastic device such as a kind of balance spring 27 guarantee valve 40 closures.
To pump 2 fuelings by high part at cylinder in formed some holes 20 obtain.These holes 20 with the chamber 21 of the pump housing 2 has a common boundary are connected on the unshowned fuel tank by conduit 22.
Suction-delivery profile the figure of pump 2 is determined in each hole 20 with respect to the location of piston 15.
As what can more be clear that in Fig. 5, conveying chamber 28 also is communicated with a pressure regulator 6 by opening 35, trunnion 30 and some suitable holes 29, and described pressure regulator is suitable for guaranteeing that fuel enters the correct pressure of sparger 8.
Said pump group 1 can be implemented the automatic change of fluctuating velocity according to the revolution of motor.
The stroke of piston, especially its speed, if under the situation that all other conditions equate, in fact directly link to each other with live axle, and therefore relevant with its revolution.Utilizing this characteristic so that have maximum fluctuating velocity under low motion speed, so that give the pressurization of described unit fast during set up procedure, and when motor is worked, obtain best fluctuating velocity value under normal running speed, in other words is lower value.Can or cannot predict a fuel recirculation loop according to pump group of the present invention, described fuel recirculation loop is made by the trunnion 23 that forms on cylinder 16, have the purpose that is recovered in the repressuring gasoline that from cylinder 16-piston 15 coupling drives, drips during the supplying step, and it is ejected in the suction chamber 21 by suitable hole 24.
Existing under the situation of recirculation, as shown in Fig. 1-5, should be noted that be used for the required amount of gasoline of recirculation must be inexcessive so that avoid overheated, described overheated causing still exists fuel rotten in the fuel tank.In this case, have one during recirculation for making gasoline return necessary fuel outlet joint 32 (Fig. 1) in the fuel tank, joint 32 becomes delegation with pressure regulator.
In an alternative embodiment, described alternative embodiment is not shown and do not equip recycling device, and outlet connection 32 does not exist, so feed unit only establishes a pipeline, is used for being fed into pump 2 from fuel tank, and does not have return branch.
In this case, the outlet of regulator 6 must be connected with chamber 21 directly or indirectly by a conduit, and above-mentioned conduit can be in the outside of pump 2 or inner.
Be used in a kind of feeding system under the situation of an indirect injection 4 two-stroke engines, packing group 50 also comprises a suction tude 3, can predict on described suction tude 3 Flexible Connector 34 that is used to connect throttling bodies is installed, and sees Fig. 1 and 2.
Although understood for example that in this manual a pump group is installed on the cluster engine head, yet should be appreciated that, the pump group also can be installed in the other zone of power unit, and also available another system that is suitable for this purposes replaces or comprise the mechanically controlled type drive system.
Can near the throttling bodies of motor, combine most of elements according to pump group of the present invention, and do not resemble 4 and take turns the similar system that automobile adopts, it has, and zero electric power absorbs and low cost, and size is little, therefore it has very low influence to the layout of automobile, and finally it does not have high pressure pipe line.
The present invention is described its preferred embodiment; be used to illustrate and hard-core purpose; but should be appreciated that; under situation about not breaking away from for this reason as the described relative protection domain of appended claims, those skilled in the art can carry out various changes and/or modification.
