Description

Single cylinder diesel decompressor
Technical field
A kind of single cylinder diesel decompressor is the utility model is related to, specifically single cylinder diesel on startup can be automatic The device of decompression is released, belongs to technical field of internal combustion engines.
Background technology
Internal combustion engine is conventional dynamic power machine, and particularly horizontal bar diesel engine is applied in fields such as agricultural machinery, Transport Machinery Widely, most horizontal bar diesel engine is all provided with manual cranking, and decompressor will be first opened in manual cranking, Single cylinder diesel unclamps decompressor again when reaching certain rotating speed, diesel engine could start, in operation operator's proficiency The manual operating crank of decompressor one is manipulated, a manual operating crank makes startup power very limited, is difficult often to start, often starts When one people manipulate decompressor, a people manipulates crank, but it is difficult to coordinate again that two people, which manipulate, therefore the manual cranking of horizontal bar diesel engine It is user's very stubborn problem.
The domestic manual cranking for horizontal bar diesel engine also has many research, for example starts front opening decompression, during startup Decompression restoring means is transmitted into the rotation of diesel engine, when diesel engine turnning circle reaches a certain amount of, device, which will depressurize, to restore in fact Now start, but because its number of turns is not the foundation of diesel engine starting, therefore can not extensive use.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, there is provided a kind of single cylinder diesel decompressor, the letter of its structure It is single, it is easy for installation, decompression can be automatically terminated in horizontal bar diesel engine starting, make operator can be with two-hand control crank, so Startability can be not only improved, makes the startup of horizontal bar diesel engine convenient.
What the purpose of this utility model was realized in:A kind of single cylinder diesel decompressor, it includes actuating unit, held Row mechanism and opener, the actuating unit includes driving wheel and driven pulley is connected, and driving wheel passes through bearing I and base Connection, driven pulley are connected by bearing I I with base, and the executing agency includes decompression lever, and one end of decompression lever is connected to decompression On axle, return spring is connected on decompression lever, the other end of decompression lever and the end of drag-line connect, the other end and the lock shaft chain of drag-line Connect, the end of lock shaft is connected with handle, and the both ends of drag-line set are separately fixed on fixed support I and fixed support II, described to open Opening mechanism includes fixed bearing pin on the driven wheel, centrifugal-block and hinge, the connecting spring on the outside of centrifugal-block, spring it is another Side connects limiting plate, and limiting plate is fixed on the driven wheel, and support bar is fixed on base, and nut is directed to plate and is fixed on support On bar.
First handle is pulled out when starting diesel engine, the lock shaft and drag-line being connected with handle move, and centrifugal-block is in spring Under effect that lock shaft is locked, because drag-line set is fixed by fixed support I and fixed support II, therefore the end of drag-line is also moved, So that the decompression lever being connected with end rotates, the decompression of diesel engine is opened.
When manipulating crank startup diesel engine, crank driving driving wheel rotates, so as to drive the driven pulley being attached thereto to rotate, Centrifugal-block is circled and compression spring, when driven pulley rotational speed reaches certain value, i.e., the centrifugal force of centrifugal-block and Centrifugation distance is when reaching setting value, and centrifugal-block releases the locking action to lock shaft, decompression lever under the elastic force effect of return spring to Back rotation, diesel engine releases decompression and started, while the end to link together, drag-line, lock shaft and handle are withdrawn into initially State.Spring is adjusted to the pressure of centrifugal-block, rotating speed when centrifugal-block unlocks to lock shaft is just changed, so as to change diesel oil The startup rotating speed of machine, adapt to different operating modes and start.
Compared with prior art, the utility model has the advantages that:
A kind of single cylinder diesel decompressor of the utility model, its is simple in construction, and operator can be subtracted with bimanualness crank Pressure automatically terminates, and adjusts the startup rotating speed of diesel engine, adapts to various operating modes, easy for installation, and it is good to start effect.
