Abstract

The utility model relates to an electromagnetic fuel switch for motorcycle, its characterized in that: the oil-discharging pipe comprises a switch body (20), an oil-feeding pipe cavity (7) and an oil-discharging pipe cavity (10), wherein the oil-discharging pipe cavity (10) is communicated with a containing cavity (8); the cavity (8) is communicated with the oil inlet pipe cavity (7) through a switch, an electromagnetic valve is fixed below the switch body (20), and when the electromagnetic valve is electrified, the oil inlet pipe cavity (7) is communicated with the cavity (8). The motorcycle can work only by using a storage battery on the motorcycle to supply power, and when a main power switch of the motorcycle is turned on, oil flows into a carburetor through the turned-on fuel switch.

Description

Motorcycle electromagnetic type fuel tap

The utility model relates to the fuel tap that a kind of motorcycle is used.

In the prior art, fuel tap in the motorcycle oil supply system (also claiming automatic lubricating cup) is opened because of the negative pressure that it relies on the motor generation, and the negative pressure that motor produces under some operating mode only can reach a very little value, sometimes even be zero, so the time fuel tap can't open because of can not get enough big negative pressure value, motor is quit work because of failure of oil feed.Manufacturer is for transportation safety and prevent Carburetor internal oxidation etc., before motorcycle dispatches from the factory, all the fuel oil in the Carburetor is drained, but motorcycle can be unpacked when selling the Consumer so again since in the Carburetor no oil to cause motorcycle to start difficult unusually.Many Consumers are defective in quality because of not knowing this cause meeting misidentification motorcycle, thereby produce many troubles between manufacturer, Consumer.

The purpose of this utility model is to provide a kind of motorcycle electromagnetic type fuel tap of being supplied with by power switch control Carburetor oil mass.

The technical solution of the utility model is: a kind of motorcycle electromagnetic type fuel tap, and it comprises switch body, be positioned at the oil-feed tube chamber of described switch body, be positioned at the fuel-displaced tube chamber of described switch body, described fuel-displaced tube chamber is connected with cavity volume; The below of described switch body is fixed with magnetic conductive shell, be provided with electromagnetic coil in the inner chamber of described magnetic conductive shell, the central part of this electromagnetic coil is provided with the electromagnetic core of longitudinal sliding motion, the top of this electromagnetic core is connected with the seal membrane that is arranged at described oil-feed tube chamber infraoral, the below of described seal membrane is provided with the spring that is enclosed within on the described electromagnetic core, when described electromagnetic core pulled down the motive sealing diaphragm, described oil-feed tube chamber was connected with cavity volume.

The utility model compared with prior art has following advantage:

Adopt solenoid valve to come the break-make of control oil channel, solenoid valve only needs to get final product work with the storage battery power supply on the motorcycle, when the main power switch of opening motorcycle, just there be the fuel tap of oil to flow in the Carburetor through opening, otherwise after turning off main power switch, fuel tap can be controlled the drawback that it is opened, breaks and produced by engine negative pressure thereby thoroughly solved immediately with the oil circuit blocking-up in the past.
