Abstract
The utility model relates to an electrical starting automatic pressure-reducing device of single diesel engines relating to the starting technical field of internal-combustion engines, wherein a pressure-reducing handle of a single cylinder diesel engine with the electrical starting performance is connected with an iron core of an electromagnetic switch, power supplies of the electromagnetic switch and a starter are controlled by one switch, after putting through the power supplies of the electromagnetic switch and the starter, the iron core of the electromagnetic switch enables the pressure-reducing handle to move, a valve of the single cylinder diesel engine is opened, the starter starts a machine under the state of reducing pressure, the needed resistance is small, the starting failures can be greatly reduced, and the cost of a starting system can be simultaneously reduced.
Description
Technical field
Electric-starting automatic pressure-reducing device of single cylinder diesel engine of the present invention relates to the engine starting technical field.
Background technique
At present, known internal-combustion engine is when adopting the electricity starting, and internal-combustion engine is to start under the situation that runs well, and that is to say it is to start under the situation of valve-closing, starting resistance is big, the power of required starter motor and storage battery is big, and starting failure is many, when the single cylinder diesel that has adopts the electricity starting, manual decompression lever is installed on existing decompressor, need people's operated valve to open and close and power switch in starting process, the two is difficult for cooperating, and causes starting failure many.
Summary of the invention
The many technical problems of starting failure when starting for solving existing one-cylinder diesel electromechanics, the invention provides a kind of electric-starting automatic pressure-reducing device of single cylinder diesel engine, mainly form by decompression shaft, decompression torsion spring, decompression handle, power supply, power switch, magnetic switch, starter motor, it is characterized in that: decompression handle is connected with the iron core of magnetic switch, magnetic switch and starter motor are controlled by a switch, and power switch is switched on or switched off starter power, magnetic switch power supply simultaneously.When connecting magnetic switch, starter power, the iron core of magnetic switch makes the decompression handle motion, open valve, starter motor starts single cylinder diesel under the situation of decompression, when the bent axle of single cylinder diesel reaches starting speed, disconnect magnetic switch, starter power, iron core resets, and the decompression handle return is closed valve, starter motor and single cylinder diesel divided flywheel obtain starting from, single cylinder diesel.
Owing to taked above technical measures, make the mechanism of decompressor and the starter motor interlock of single cylinder diesel, single cylinder diesel is to obtain starting under the state of decompression, required actuating motor, little many of storage battery power, thus starting failure can greatly be reduced, and can reduce the cost of electric starting system.
Description of drawings
Fig. 1. be structural representation of the present invention
Fig. 2. be the embodiment of the invention 2 structural representations
Fig. 3. be example 3 structural representations of the present invention
1 decompression shaft, 2 decompression shaft torsion springs, 3 decompression handles are the original parts of single cylinder diesel among Fig. 1, and 3 decompression handles are connected with 4 iron cores of 5 magnetic switch.5 magnetic switch, 6 starter powers by 8 power switches control, 8 power switches connect 9 power supplys.
Embodiment
When needs starting single cylinder diesel, connect 5 magnetic switch, 6 starter powers by 8 power switches, 4 iron cores of 5 magnetic switch drive 3 decompression handles and open valve, single cylinder diesel is in 6 starter motors running under the decompression state, when the one-cylinder diesel machine crankshaft reaches starting speed, disconnect 5 magnetic switch, 6 starter powers, 4 iron cores reset, under the effect of 2 decompression torsion springs, 3 decompression handle returns, single cylinder diesel valve-closing, single cylinder diesel obtain starting, and 6 starter gears separate with the single cylinder diesel flywheel teeth.
Accompanying drawing 2 is another kind of forms of 8 power switches in the embodiment of the invention 2.8 power switches and 9 power connections, the A on 8 power switches, B are respectively 5 magnetic switch power contacts, 6 starter power contacts, and 5 magnetic switch switch on and off prior to 6 starter motors, and this is more conducive to improve startability.
4 iron cores in 7 starter relays among Fig. 3 on 3 decompression handles and 6 starter motors are connected, 8 power switches are connected 7 starter relay power supplys, 4 iron cores on 7 starter relays move the one-way element on 3 decompression handles and the starter motor simultaneously, 6 starter motors are realized decompression state starting down, the bent axle of single cylinder cylinder diesel reaches starting speed, 8 power switches disconnect 7 starter relay power supplys, 4 iron cores make 3 decompression handle returns close valve, one-way element return, single cylinder diesel obtain starting.
