Abstract
The utility model relates to an oil suction pump of a carburetor which is provided with a hidden oil storage body, which relates to an improvement and an invention of an oil pumping device and the oil storage body of the oil suction pump. The utility model comprises the oil pumping device and the oil storage body, wherein, the oil pumping device is communicated with an oil tank by an oil suction pipe (2) and is communicated with an oil storage chamber (1) of the oil storage body by an oil delivery pipe (3), and the oil storage chamber (1) is communicated with the carburetor by an oil guiding pipe (6). The chamber wall of the oil storage chamber (1) is provided with an overflow orifice (4) which is used for controlling the oil level, and the oil storage body is arranged in the oil tank. The oil suction pump of the carburetor which is designed according to the topic of the utility model overcomes the defects of oil waste, body contamination, easy firing and explosion, etc. due to liquid leakage and ensures the use safety of the carburetor. The utility model is especially suitable for engines large power.
Description
(1) technical field
The Carburetor oil scavenge pump that the utlity model has concealed oil container relates to the oil scavenge pump topology layout, and particularly oil container is provided with the position.
(2) background technique
In the prior art, the oil pumping device of Carburetor oil scavenge pump for to the Carburetor fuel feeding, is arranged on one with Carburetor with store oil usually, causes Carburetor overall structure very complicated, is difficult to processing, adds and occurs waste product easily man-hour, has improved the Carburetor cost of production.In addition in long-term the use, easy fault, repair rate height.Moreover have the defective of leaking oil, and leakage of oil is not only wasted and is easily stain member, also has the danger of blast on fire, and especially at more powerful motor, Security is a ten minutes distinct issues.
(3) summary of the invention
The oil container that the utility model aims to provide a kind of oil scavenge pump is arranged on the device in the fuel tank, reaches to simplify the oil scavenge pump project organization, the purpose of the caused relevant harm of oil of thoroughly stopping a leak.
The utility model is finished as follows: comprise oil pumping device and oil container, this oil pumping device is communicated with fuel tank by fuel sucking pipe, this oil pumping device is communicated with the reservoir compartment of oil container by sending oil pipe, described reservoir compartment is communicated with Carburetor by oil guide pipe, the locular wall of reservoir compartment is provided with the overflow hole in order to control fuel head, and described oil container is arranged in the fuel tank.
Carburetor oil scavenge pump by the design of the utility model theme with concealed oil container, because oil container is set directly in the fuel tank, even the full oil of oil container leakage of oil or oil container pump, fluid also can directly enter fuel tank, and do not contact the external world, particularly at more powerful motor, safety coefficient is able to absolute assurance.
(4) description of drawings
Fig. 1 is the utility model structure principle chart
Embodiment
Accompanying drawing has been represented the utility model structural principle, describe embodiment in detail below in conjunction with the accompanying drawing progress: comprise oil pumping device and oil container, oil pumping device can adopt bent axle mode pump oil, this oil pumping device is communicated with fuel tank by fuel sucking pipe (2), this oil pumping device is communicated with the reservoir compartment (1) of oil container by sending oil pipe (3), described reservoir compartment (1) is communicated with Carburetor by oil guide pipe (6), and the locular wall of reservoir compartment (1) is provided with the overflow hole (4) in order to control fuel head.Described oil container is arranged in the fuel tank, oil spill goes out or leaks directly to enter fuel tank, the oil container setting is comparatively hiding, exhausted its extraneous directly contact of figure, this device is specially adapted to more powerful motor hair oil device, for cooperating it to need oil pumping device to be set to oil pumping body, this oil pumping body is by last, lower body is sealedly and fixedly connected and forms, on, be provided with active chamber between the lower body, this active chamber is by on being positioned at, oil suction diaphragm (5) between the lower body is divided into air cavity (7), oil suction chamber (8), air cavity (7), oil suction chamber (8) lays respectively at, on the lower body, air cavity (7) is communicated with engine inlets, oil suction chamber (8) is by successively passing through down, the suction passage of upper body (9) is communicated with fuel sucking pipe (2), this suction passage (9) sets unidirectional input valvular valve (11), oil suction chamber (8) is by successively passing through down, oil pipe (3) is sent in the oil discharge passage of upper body (10) connection, oil discharge passage (10) sets unidirectional output valvular valve (12), unidirectional input valvular valve (11), unidirectional output valvular valve (12) is formed whole diaphragm with oil suction diaphragm (5), is easy to process and the setting of valve.Pump pressure in order to increase fluid, between oil suction diaphragm (5) and air cavity (7), be provided with the spring (13) that is installed in the air cavity (7).When motor is air-breathing, flexible sheet moves to the air cavity top in the barometric pressure effect, this moment, oil pocket formed negative pressure, then unidirectional input valvular valve is opened to the oil suction chamber fuel feeding, when engine exhaust, flexible sheet is under self elastic force and the effect of spring restoring force, do to reply fast moving, press in the oil suction chamber to increase, unidirectional input valvular valve is closed, and unidirectional output valvular valve is opened to the oil container fuel feeding, when the oil container storage is expired oil, overflow by overflow hole, thereby controlled the interior oil mass of oil container, go round and begin again like this and realize Carburetor fuel feeding and control.Do not damage the oil suction diaphragm when contacting work for spring with the oil suction diaphragm, be provided with pad lid (15) between spring (13) and oil suction diaphragm (5), this pad lid (15) places oil suction diaphragm (5) to go up and forms in the pit that is complementary with the pad lid, prevents the displacement of pad lid.In order to make the oil circuit operating mode stable over a long time, the termination that is dipped in the fuel tank at fuel sucking pipe (2) is provided with filter screen (14), guarantees that the oil of oil circuit is comparatively pure, avoids scum juice to stop up oil circuit.
