Abstract
The utility model provides an inner-placed breather of a single cylinder diesel engine and the breather can effectively overcome the flaw of oil leakage and comprises a breather shell, a cover plate arranged on the breather shell, a shield cover of the breather arranged on the cover plate, an air inlet arranged on the cover plate, a diaphragm which is covered on the air inlet and is fixed on the cover plate by a pressing plate, a air breathing hole which is accessible to the outside and is arranged on the breather shell and filtration substance of oil gas arranged in the cushion chamber of the breather shell. The flaw of oil leakage of the inner-placed breather of the single cylinder diesel engine is effectively overcome.
Description
Technical field
The utility model relates to Diesel Engine Breather, particularly the built-in resuscitation apparatus of single cylinder diesel.
Background technique
At present, the various single cylinder diesels of domestic production are widely used in tractor, generator mating power, three-wheel locomotive, irrigation and drainage etc.And resuscitation apparatus to be single cylinder diesel be used for reducing diesel engine oil seepage reduces the requisite parts of consumption of lubricating oil.Existing built-in resuscitation apparatus, contain ventilator housing, cover plate is housed on the ventilator housing, the resuscitation apparatus cover cap on the cover board is housed, cover plate is provided with inlet hole, is coated with diaphragm on the inlet hole, and diaphragm is fixing on the cover board by compressing tablet, compressing tablet is the sheet slab construction, also is provided with outer logical exhaling hole on the ventilator housing.Because the operating temperature of diesel engine inner chamber machine oil is about 95 ℃, during diesel engine work, the high speed rotating of its inner chamber gear drive stirs, produced the tiny oil droplet that splashes in a large number, though on the cover board the resuscitation apparatus cover cap is equipped with in the side, the machine oil oil droplet that major part is splashed flows away after having fallen on the resuscitation apparatus cover cap, but also have a spot of oil droplet to pass through inlet hole, through buffer cavity, it is external to breathe out with air-flow, makes single cylinder diesel produce oil leakage phenomenon.
Summary of the invention
The utility model purpose is to provide a kind of built-in resuscitation apparatus that can effectively overcome the single cylinder diesel of leakage of oil defective.
Solution of the present utility model is: contain ventilator housing, cover plate is housed on the ventilator housing, the resuscitation apparatus cover cap on the cover board is housed, cover plate is provided with inlet hole, be coated with diaphragm on the inlet hole, diaphragm is fixing on the cover board by compressing tablet, also is provided with outer logical exhaling hole on the ventilator housing, is provided with the hydrocarbon filter thing in the buffer cavity of ventilator housing.
Be provided with the hydrocarbon filter dividing plate in the buffer cavity of ventilator housing, the hydrocarbon filter dividing plate is provided with some oil gas through holes, is filled with the hydrocarbon filter silk screen between hydrocarbon filter dividing plate and the outer logical exhaling hole.
The beneficial effects of the utility model are, owing to be provided with the hydrocarbon filter thing in the buffer cavity of ventilator housing, the machine oil oil droplet that splashes enters buffer cavity with air-flow, after hydrocarbon filter dividing plate and hydrocarbon filter silk screen filter, air-flow is breathed out external through outer logical exhaling hole, the machine oil of aggegation on hydrocarbon filter dividing plate and hydrocarbon filter silk screen flows to the bottom of ventilator housing, is discharged in the diesel engine inner chamber through the draining hole, has effectively overcome the leakage of oil defective of the built-in resuscitation apparatus of single cylinder diesel.
Description of drawings
Accompanying drawing has provided embodiment of the present utility model.
Fig. 1 is model utility embodiment's a structural representation;
Fig. 2 is model utility embodiment's an A-A sectional view.
Among the figure: 1--draining hole; The 2--buffer cavity; The logical outward fastening double-purpose bolt of exhaling of 3--; 4--hydrocarbon filter silk screen; 5--oil gas through hole; The 6--compressing tablet; The 7--rivet; 8--resuscitation apparatus cover cap; The 9--screw; The 10--cover plate; The 11--diaphragm; The 12--inlet hole; The 13--supporting post; 14--hydrocarbon filter dividing plate; The 15--ventilator housing; The logical outward exhaling hole of 16--.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Contain ventilator housing 15, be fixed with cover plate 10 on the ventilator housing 15, resuscitation apparatus cover cap 8 is housed on cover plate 10, cover plate 10 and resuscitation apparatus cover cap 8 are bound up on the supporting post 13 in the ventilator housing 15 by screw 9, also be provided with inlet hole 12 on the cover plate 10, be coated with diaphragm 11 on the inlet hole 12, diaphragm 11 and compressing tablet 6 are tied on cover plate 10 by rivet 7 rivetings, be provided with the hydrocarbon filter thing in the buffer cavity 2 of ventilator housing 15, the hydrocarbon filter thing is made up of hydrocarbon filter dividing plate 14 and hydrocarbon filter silk screen 4, hydrocarbon filter dividing plate 14 is provided with some oil gas through holes 5, and hydrocarbon filter silk screen 4 is filled between hydrocarbon filter dividing plate 14 and the outer logical exhaling hole 16.
In the working process of diesel engine, its inner chamber leaks and produces pulse pneumatic, when pulse pneumatic passes through inlet hole 12, diaphragm 11 is produced the pulsation Driving force, make diaphragm 11 produce vibration synchronously, when the pulse pneumatic impulse force reached the high value, diaphragm 11 opened, pulse pneumatic enters in the buffer cavity 2, and from outside breathe out the logical fastening double-purpose bolt 3 of exhaling.When the pulse pneumatic impulse force was low value, the elastic restoring force of diaphragm 11 utilizations itself and cover plate 10 were fitted, and inlet hole 12 is closed, and guarantee the air-flow only import but no export, thereby made the atmospheric pressure value in the diesel engine inner chamber be lower than outer about 200 column of normal atmosphere (An) value of diesel engine.The operating temperature of diesel engine inner chamber machine oil is about 95 ℃, during diesel engine work, the high speed rotating of its inner chamber gear drive stirs, produced the tiny oil droplet that splashes in a large number, after falling on the resuscitation apparatus cover cap 8, the machine oil oil droplet major part of splashing flows away, a small amount of oil droplet is crossed inlet hole 12 with air communication and is entered buffer cavity 2, after hydrocarbon filter dividing plate 14 and 4 filtrations of hydrocarbon filter silk screen, air-flow is breathed out external through outer logical exhaling hole 16, the machine oil of aggegation on hydrocarbon filter dividing plate 14 and hydrocarbon filter silk screen 4 flows to the bottom of ventilator housing 15, is discharged in the diesel engine inner chamber through draining hole 1.
