Abstract
The utility model discloses an automatic decompressor for a single cylinder diesel, relating to the technical field of combustion engine starting. A bracing wire is fixed on a movable iron core of an electromagnet, the other end of the bracing wire is connected with a decompression handle, and an electromagnet control circuit and a starter electromagnetic switch control circuit are both connected with an ignition switch. As an electromagnet circuit is connected earlier than the starter electromagnetic switch circuit, and is disconnected earlier than the starter electromagnetic switch circuit, the single cylinder diesel can be started under the state without compression resistance, so that the starting resistance can be reduced, therefore, the failure rates of a starter and a starting line are reduced greatly, and the technical aims of low cost and high reliability can be realized.
Description
Technical field
Single cylinder diesel automatic pressure-reducing device of the present invention relates to the engine starting technical field.
Background technique
There are surface friction drag, inertial resistance, resistance to compression pression during engine starting, wherein main is resistance to compression pression, for the internal-combustion engine of taking hand primer, people are in order to reduce the starting resistance of internal-combustion engine, improve starting performance, designed by decompression shaft, relief cam, the manual decompression starting device that component such as decompression handle are formed is when starting, pull decompression handle by manpower, relief cam is opened valve, makes in the cylinder barrel not have pressurized gas, has eliminated resistance to compression pression, thereby be beneficial to the starting of internal-combustion engine, single cylinder diesel all is provided with decompressor.At present, single cylinder diesel existing nearly 50% adopts the electricity starting, resistance when starting in order to reduce, adopt the single cylinder diesel of electricity starting that manual decompressor still is set, the normal running of this electricity starting should be to pull decompressor by hand earlier valve is opened, again by ignition switch conducting starter circuit capable, by starter motor starting diesel engine, but reality is, people are the inoperation decompressor nearly all, but directly use the starter motor cranking internal combustion engine, like this, big at starting resistance, start under the big situation of starting current, cause the starter motor rate of fault very high, be head it off, Chinese patent application 200410014537.X, Chinese patent application 200910221357.1 has proposed no longer to be operated by the people the automatic decompression starting device of decompressor, utilization is by decompression shaft, relief cam, the manual decompression starting device that component such as decompression handle are formed spurs decompression handle with electromagnet, Chinese patent application 200410014537.X, be provided with delay control circuit in the control circuit of electromagnet, the defective of this scheme is the higher and poor reliability of cost.Single cylinder diesel is a farm machinery in China basically, and very strong to the susceptibility of cost, again, Environmental Conditions is abominable, and the electronic component in the delay control circuit is required height, and its cost is higher.Chinese patent application 200910221357.1 is to utilize the decompressor of the moving iron core pulling single cylinder diesel of the original magnetic switch of starter motor, after the valve-closing, the circuit of actuating motor is controlled by ignition switch, the defective of this scheme is that the circuital current of actuating motor of ignition switch control is limited and limited by current"on"time, start some difficulty in the winter time, some is poor for reliability.
Summary of the invention
In order to solve the single cylinder diesel starting difficulty, reduce the starter motor fault, and reliability also can be guaranteed under cost of the end, the present invention proposes a kind of single cylinder diesel automatic pressure-reducing device, mainly by electromagnet, backguy, starter relay, ignition switch is formed, it is characterized in that: fixedly backguy on the moving iron core of electromagnet, the other end of backguy connects decompression handle, control circuit for electromagnet all is connected with ignition switch with the starter relay control circuit, the conducting of control circuit for electromagnet and starter relay control circuit is all controlled by ignition switch with disconnection, the circuit of electromagnet is prior to the starter relay circuit turn-on, and the disconnection of solenoid circuit is prior to the disconnection of starter relay circuit.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Embodiment
The moving fixedly backguy 2 of iron core 3 of electromagnet among the figure, the other end of backguy 2 connects decompression handle 1, the A gear that control circuit for electromagnet 5 connects on the ignition switch 8, the conducting of electromagnet 4 circuit is all controlled by ignition switch 8 with disconnection, the B gear that starter relay control circuit 6 connects on the ignition switch 8, when needs starting single cylinder diesel, rotation ignition switch 8, the circuit of electromagnet 4 is prior to the circuit turn-on of starter relay 7, the circuit of the circuit of electromagnet 4 and starter relay 7 all is in the conducting shape during to the A gear, and the moving iron core 3 pulling backguys 2 of electromagnet make decompression handle 1 action, and valve is opened, internal-combustion engine starts under no resistance to compression pression state, stop 1-2 second at the A of ignition switch 8 gear, internal combustion engine flywheel reaches starting speed, rotation ignition switch 8 to B gears, the circuit of electromagnet 4 disconnects, electromagnet moves iron core 3 returns, and valve-closing is after internal-combustion engine obtains starting, unclamp ignition switch 8, disconnect the circuit of starter relay 7.
Among the present invention, the moving iron core 3 of electromagnet is that connecting rod is connected with the another kind of Placement of decompression handle 1.
Owing to taked above technical measures, realized that not only single cylinder diesel starts under no resistance to compression pression state, reduce starting resistance, starter motor, trigger circuit rate of fault are greatly reduced, realized technical goal low-cost, high reliability simultaneously.
