Description
Technical field
The present invention relates to a kind of carburetor, more particularly to a kind of vertical lift oil plane carburetor.
Background technology
Domestic carburetor is generally using welding monoblock type Floater Structure, this float arm and floating body monoblock type at present
Connection type, occupied space is big, and float motion control stroke is short, slow into speed oil, does not provide sufficient oil plane, and float
Movement is not sensitive enough, can not accurately control oil plane, be susceptible to the phenomenon that float blocks, float volume is small, and buoyancy is small, can not
Reliable leakproofness is provided, carburetor oil leak is caused, influences carburetor normal use, there are hidden danger safe to use.
Invention content
The purpose of the present invention is to provide a kind of vertical lift oil plane carburetors, and this carburettor float stroke is long, into
Oil mass is big, can not only provide sufficient carburetor oil plane, but also individual vertical lifts Floater Structure high sensitivity, can be accurate
Control oil plane in carburettor float room.In addition, this carburetor occupancy is small, it can suitably increase float volume, to increase
Add buoyancy to provide reliable leakproofness, eliminates hidden danger safe to use existing for carburetor oil leak.
The invention is realized in this way：A kind of vertical lift oil plane carburetor, which includes carburetor body,
It is characterized in that：Carburetor bowl, in line check valve seat, oil inlet needle, oil inlet needle hook, float are equipped in carburetor body
Rocking arm, independent float, float lifting guiding axis, float pin, float rotation axis；One end of the in line check valve seat with it is external into
Oil-piping is connected, and the other end is set in the carburettor float room, is equipped in the in line check valve pedestal and is used for being connected to outside
The axial fuel inlet hole of inflow pipeline and carburetor bowl, the oil inlet needle activity are assemblied in axial fuel inlet hole and can be opposite
Axial fuel inlet hole moves axially；The oil inlet needle hook is connect with oil inlet needle bottom；The float lifting guiding axis is perpendicular to be set
It is connected in carburettor float room and with carburetor body fixed installation；The independent float activity is assemblied in the float lifting
On guiding axis and guiding axis can be lifted along float it be vertically moved up or down and move in carburettor float room；The float pin and independent float
It is fixedly connected and parts transversely is placed on outside independent floating body；The float rotation axis cross in carburettor float room and with
Connection is fixedly mounted in carburetor body；The front end of the float rocking arm is rotatablely connected with float rotation axis, middle part hook be placed in into
In fuel tap needle hook, tail portion rides on the float pin.
Float volume in order to further increase provides reliable leakproofness to increase buoyancy, eliminates existing for carburetor oil leak
The quantity of hidden danger safe to use, the independent float and float pin is two and is symmetrically disposed in line check valve seat both sides, institute
It is consistent with the quantity of independent float to state float pin, the quantity of float lifting guiding axis.Symmetrically arranged independent float can also carry
High mechanism traveling comfort.
In order to facilitate the elevating movement of the independent float in the synchronous interaction control left and right sides, the float rocking arm includes being located at it
Front end and cross between two independent floats sleeve, be divided at left and right sides of sleeve be used for ride over two float pins respectively
On control-rod and be fixed on sleeve lateral wall be used for oil inlet needle hook hook set the tongue connecting, the sleeve and float
Rotation axis is rotatablely connected, the control-rod and tongue with sleeve vertical connection and be directed toward the same side.
