Description
Technical field
The utility model relates to a kind of large discharge capacity Carburetor oil feeding device.
Background technique
Current existing Carburetor oil feeding device is applicable to common small displacement Carburetor, is mainly to rely on needle to coordinate control oil inlet quantity with the bore clearance of pintle valve seat, does not have the supplementary gasoline of additional channels to enter carburettor float indoor.And needle head generally adopts rubber material, Carburetor, when not using for a long time, there will be needle head to stick in pintle valve seat, causes needle and the needle-valve can not flexible motion, there will be the phenomenons such as not oil-feed of Carburetor or leakage of oil, affect the normal use of Carburetor.
While working due to large-duty engine, fuel consumption is larger, to the oil feeding device of Carburetor, require higher, if use the oil feeding device of small displacement Carburetor in the past to there will be the phenomenon of supplying oil of carburetor deficiency, while encountering anxious acceleration, high-speed working condition, carburettor float is indoor does not have supplementing of extra gasoline, can affect the usability of Carburetor because produce the performance issues such as anxious acceleration does not increase, transition is bad for shortage of oil, especially in racing car, the defect of oil-feed deficiency is more obvious.
Model utility content
The purpose of this utility model is to provide a kind of large discharge capacity Carburetor oil feeding device, it not only can pass through the devices such as float, oil-feed needle and control oil-feed process, and can provide and stablize sufficient gas supply engine system and use, avoid large discharge capacity Carburetor to occur in using for shortage of oil and produce the performance issue such as suddenly accelerating can not add, transition is bad, draw to get at a high speed.
The utility model is achieved in that a kind of large discharge capacity Carburetor oil feeding device, it comprises Carburetor body, is provided with oil inlet pipe, oil inlet passage, in line check valve seat, oil-feed needle, oil-feed needle hook, float, carburetor bowl and float pin in Carburetor body; Oil inlet pipe is installed on the ingress of oil inlet passage; One end of in line check valve seat is connected with oil inlet passage, and it is indoor that the other end is located at carburettor float; In in line check valve pedestal, be provided with for being communicated with the axial fuel inlet hole of oil inlet passage and carburetor bowl, the activity of oil-feed needle be assemblied in axial fuel inlet hole and to axial oil inlet hole move axially with opening-closing shaft to oil inlet hole; Oil-feed needle bottom connects with oil-feed needle hook connecting, and one end of oil-feed needle hook is rotationally connected with the float pin being fixedly installed in Carburetor body body, and the other end float indoor with being located at carburettor float is connected; The sidewall of described in line check valve seat is also provided with a side direction oil inlet hole that is used for above making axial fuel inlet hole and carburetor bowl lateral communication.
In addition; for fear of the rubber head because of oil-feed needle, stick in line check valve seat; cause oil-feed needle and the in line check valve seat can not flexible motion; and there is the phenomenons such as not oil-feed of Carburetor or leakage of oil; the utility model technique scheme has also been done following improvement: described oil-feed needle is formed by fixedly connecting by the stainless steel part of bottom and the cone rubber head at top, and the outside of described cone rubber head is also coated with molybdenum disulfide protective layer.
For the ease of smooth oil-feed, the quantity of described side direction oil inlet hole is two, and two side direction oil inlet holes are symmetricly set in line check valve seat both sides.
Compared to prior art, the utlity model has following advantage:
(1) the utility model adopts float, oil-feed needle hook to control the keying that oil-feed needle moves up and down to control oil inlet passage, and in line check valve seat, be provided with axial fuel inlet hole and side direction oil inlet hole, not only can be by the gap axial fuel inlet between oil-feed needle and axial fuel inlet hole, also can pass through the oil-feed of side direction oil inlet hole side direction, avoided occurring the performance issues such as the anxious acceleration of the generation causing for shortage of oil can add, transition is bad, high speed is drawn to get in large discharge capacity Carburetor use, also eliminated the potential safety hazards such as not oil-feed, leakage of oil simultaneously.
(2) due to oil-feed needle of the present utility model, by stainless steel part and external spray, the rubber head by molybdenum disulfide protective layer forms; therefore the cone rubber head that can effectively prevent oil-feed needle sticks in line check valve pedestal, can avoid because of phenomenons such as the not oil-feed of Carburetor can not flexible motion occurring of needle and valve seat or leakage of oils.
(3) the utility model not only can provide and stablize sufficient gas supply engine system use, and simple in structure, and assembly and disassembly is convenient, and low cost of manufacture, is easy to apply.

Embodiment
Below in conjunction with Figure of description and specific embodiment, the utility model content is elaborated:
As Figure 1-Figure 5, the example structure schematic diagram of oil feeding device for a kind of large discharge capacity Carburetor providing for the utility model, in figure, this device comprises Carburetor body 1, is provided with oil inlet pipe 2, oil inlet passage 3, in line check valve seat 4, oil-feed needle 5, oil-feed needle hook 6, float 7, carburetor bowl 8 and float pin 9 in Carburetor body 1; Oil inlet pipe 2 is installed on the ingress of oil inlet passage 3; One end of in line check valve seat 4 is connected with oil inlet passage 3, and the other end is located in carburetor bowl 8; In in line check valve seat 4 bodies, be provided with for being communicated with the axial fuel inlet hole 10 of oil inlet passage 3 and carburetor bowl 8,5 activities of oil-feed needle be assemblied in axial fuel inlet hole 10 and to axial oil inlet hole 10 move axially to control the oil circuit break-make between oil inlet passage 3 and carburetor bowl 8; The bottom of oil-feed needle 5 is connected with oil-feed needle hook 6, and one end of oil-feed needle hook 6 is rotationally connected with the float pin 9 being fixedly installed in Carburetor body 1 body, and the other end is connected with the float 7 in being located at carburetor bowl 8; The sidewall of described in line check valve seat 4 is also provided with a side direction oil inlet hole 11 that is used for above making axial fuel inlet hole 10 and carburetor bowl 8 lateral communications.When carburetor bowl 8 interior gasoline hungry, float 7 declines by oil-feed needle hook 6 around float pin 9, drive oil-feed needle 5 to decline, the axial fuel inlet hole 10 of gasoline from one-way valve seat 4 enters, and a part of gasoline enters in carburetor bowl 8 from the side direction oil inlet hole of in line check valve seat 4 sidewalls.When gasoline reaches oily plan-position, float 7 rises under the buoyancy of gasoline, withstands oil-feed needle 5, thereby closes the oil inlet hole in line check valve seat 4.
In addition; for fear of the rubber head because of oil-feed needle 5, stick in line check valve seat 4; cause oil-feed needle 5 and the in line check valve seat 4 can not flexible motion; and there is the phenomenons such as not oil-feed of Carburetor or leakage of oil; the utility model technique scheme has also been done following improvement: described oil-feed needle 5 is formed by fixedly connecting by the stainless steel part of bottom and the cone rubber head at top, and the outside of described cone rubber head is also coated with molybdenum disulfide protective layer.
For the ease of smooth oil-feed, the quantity of described side direction oil inlet hole 11 is two, and two side direction oil inlet holes 11 are symmetricly set in line check valve seat 4 both sides.
Above-mentioned embodiment is just explained in detail the technical solution of the utility model; the utility model has more than and is only confined to above-described embodiment; every any improvement or replacement according to the utility model principle, all should be within protection domain of the present utility model.
