Abstract
The utility model discloses a kind of rebreather of engine, comprise resuscitation apparatus body, resuscitation apparatus body is provided with the air outlet and suction port that are communicated with resuscitation apparatus chamber body, the bottom of resuscitation apparatus chamber body is that the sidepiece of shoe cream room resuscitation apparatus body is provided with deaerator return tube, rebreather of engine integrated external oil collecting gas separating device drainback passage, this rebreather of engine is possessed simultaneously and gets gas and oil return function, reduce machine part quantity, deaerator return tube extend in shoe cream room, the gap can flowed for oil return is left between bottom the end of deaerator return tube and shoe cream room, the end of such deaerator return tube is below shoe cream room liquid level, the end that deaerator return tube can be positioned at shoe cream room seals, seal by return opening, thus prevent crankcase gas blowby from entering in deaerator return tube, play the effect preventing return tube gas blowby.
Description
Technical field
The utility model relates to a kind of rebreather of engine.
Background technique
Rebreather of engine is discharged with the waste gas of crankcase to reduce machine oil, in prior art, rebreather of engine and deaerator are arranged on complete machine respectively, gas got by deaerator and oil return is respectively two component, and majority is in comparatively distant positions, general oil-returning structure is arranged in the middle part of oil sump or body, get gas position then in motor head gear chamber position, when deaerator position is in time getting gas, distance oil return position is far away, line arrangement is longer, waste resource, and space is arranged improper.
Model utility content
The technical problems to be solved in the utility model is for above-mentioned defect, provide a kind of rebreather of engine, this rebreather of engine integrated external oil collecting gas separating device drainback passage, this rebreather of engine is possessed simultaneously and gets gas and oil return function, reduce machine part quantity, and return tube gas blowby can be prevented.
In order to solve the problems of the technologies described above, the utility model comprises resuscitation apparatus body, described resuscitation apparatus body is provided with the air outlet and suction port that are communicated with resuscitation apparatus chamber body, the bottom of described resuscitation apparatus chamber body is shoe cream room, its structural feature is: the sidepiece of described resuscitation apparatus body is provided with deaerator return tube, and described deaerator return tube extend in shoe cream room.
The sidepiece described resuscitation apparatus body being installed deaerator return tube is provided with the mounting shell connected as one with resuscitation apparatus body, and the inner chamber of mounting shell is communicated with resuscitation apparatus chamber body, shoe cream room.
Described deaerator return tube partially passes through mounting shell and extend into an end away from air outlet in the inner chamber of mounting shell.
Away from leaving the gap can flowed for oil body between end, air outlet one in the end of described deaerator return tube in shoe cream room and mounting shell inner chamber.
The setting direction that setting direction and the deaerator return tube of described air outlet are positioned at part beyond mounting shell is parallel.
Compared with prior art the utility model has the following advantages: the sidepiece of resuscitation apparatus body is provided with deaerator return tube, rebreather of engine integrated external oil collecting gas separating device drainback passage, this rebreather of engine is possessed simultaneously and gets gas and oil return function, reduce machine part quantity, the sidepiece of resuscitation apparatus body is provided with the mounting shell connected as one with resuscitation apparatus body, the inner chamber of mounting shell and resuscitation apparatus chamber body, shoe cream room is communicated with, deaerator return tube enters in shoe cream room through mounting shell inner chamber, the resuscitation apparatus of this structure makes return tube need not receive oil sump or other positions, decrease complete machine amount of parts, and shorten the length of return tube to a certain extent, the gap can flowed for oil return is left between bottom the end of deaerator return tube and shoe cream room, the end of such deaerator return tube is below shoe cream room liquid level, the end that deaerator return tube can be positioned at shoe cream room seals, seal by return opening, thus prevent crankcase gas blowby from entering in deaerator return tube, play the effect preventing return tube gas blowby, resuscitation apparatus can multi-angle use, and all can realize oil sealing effect, prevent assembling deviation from causing afunction phenomenon, and can under multiple layout angle, utilize liquid level difference to prevent return tube gas blowby.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is A direction view in Fig. 1;
Fig. 3 be in Fig. 1 B-B to sectional view;
Fig. 4 is another setting angle schematic diagram of the utility model.
Embodiment
As shown in the figure, rebreather of engine comprises resuscitation apparatus body 1, resuscitation apparatus body 1 is provided with the air outlet 2 and suction port 3 that are communicated with resuscitation apparatus chamber body, the bottom of resuscitation apparatus chamber body is shoe cream room 6, suction port 3 is connected with crankcase, and the air-fuel mixture gas in crankcase is entered by suction port 3 in the inner chamber of resuscitation apparatus body 1 and carries out Oil-gas Separation, and the fluid after separation enters shoe cream room 6, and returning in crankcase, the gas after separation is discharged by air outlet 2.The sidepiece of resuscitation apparatus body 1 is provided with deaerator return tube 4, and an end of deaerator return tube 4 is connected with deaerator, and the other end of deaerator return tube 4 extend in shoe cream room 6.The sidepiece in the present embodiment, resuscitation apparatus body 1 being installed deaerator return tube 4 is provided with the mounting shell 5 connected as one with resuscitation apparatus body 1, and the inner chamber of mounting shell 5 is communicated with resuscitation apparatus chamber body, shoe cream room 6.The setting direction that setting direction and the deaerator return tube 4 of air outlet 2 are positioned at part beyond mounting shell 5 is parallel, is convenient to arrangement, saves space.The resuscitation apparatus of this structure is integrated with externally connected type deaerator drainback passage, makes return tube need not receive oil sump or other positions, decreases complete machine amount of parts, and shorten the length of return tube to a certain extent.Deaerator return tube 4 the other end extend into the end away from air outlet 2 in the inner chamber of mounting shell 5 through mounting shell 5, can store that a part is flowed back to by deaerator return tube 4 or by the oil return of separating in air-fuel mixture gas in shoe cream room 6, away from leaving the gap can flowed for oil body between end, air outlet 2 one in the end of deaerator return tube 4 in shoe cream room 6 and mounting shell 5 inner chamber, the end of such deaerator return tube 4 is below shoe cream room 6 liquid level, the end that deaerator return tube 4 can be positioned at shoe cream room 6 seals, seal by return opening, thus prevent crankcase gas blowby from entering in deaerator return tube 4, play the effect preventing return tube gas blowby.
In the present embodiment, resuscitation apparatus can multi-angle use, and all can realize oil sealing effect, prevent assembling deviation from causing afunction phenomenon, and can under multiple layout angle, utilize liquid level difference to prevent return tube gas blowby.
The above is specific constructive form of the present utility model; the utility model is not restricted to the described embodiments; the art personnel, replace all in protection domain of the present utility model based on the equivalent variations of concrete structure on the utility model and parts.
