Abstract
The utility model relates to a close-typed oil gas separation device used for an engine, comprising a cylinder body, a cylinder cover which is arranged on the upper end of the cylinder body, a cylinder hood which is arranged on the cylinder cover and an oil bottom shell which is connected with the lower end of the cylinder body; the side wall of the cylinder hood is provided with an oil gas separator which comprises an air inlet pipe that is connected with the cylinder hood, an oil returning pipe which is connected with the oil bottom shell and an exhaust pipe which is connected with the atmosphere. The close-typed oil gas separation has the advantages that: after the oil and gas are separated in the separator, the machine oil can flow back into the oil bottom shell along the oil returning pipe in time and be avoided from being accumulated and coked in the separator; the structure of the separator is not damaged after long-term use and good separation performance thereof is ensured, furthermore, the machine oil can be sufficiently circulated and utilized and the cost is reduced; furthermore, the close-typed oil gas separation mechanism has small and simple structure and convenient replacement, has a certain interchangeability with the original structure and is convenient for the maintenance and curing of the user on the vehicle.
Description
Technical field
The utility model belongs to gas and oil separating plant, particularly relates to a kind of engine oil air separation.
Background technique
Gas and oil separating plant mainly is to reclaim machine oil in the exhaust of cylinder cap respirating tube.The gas and oil separating plant that uses on the existing motor is to install to have cancellated resuscitation apparatus on cylinder head cover, and connects respirating tube.This is simple in structure, the use initial stage can be played the effect of separation oil and gas, but because after long-time the use, high temperature oil can deposit on reticular structure, coking, has destroyed the effect of original structure, must frequently change resuscitation apparatus to guarantee Oil-gas Separation, cause its cost to increase, adopt above-mentioned cancellated resuscitation apparatus in addition, because deposition, the coking of high temperature oil, machine oil can not be fine recycling in the oil gas, caused the waste of the energy.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, change engine oil air separation easily.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of engine oil air separation, comprise cylinder head cover of installing on the cylinder cap, cylinder cap of cylinder body, cylinder body upper end and the oil sump that links to each other with the cylinder body lower end, it is characterized in that: on the cylinder head cover sidewall, deaerator is installed, described deaerator comprises, the suction tude that links to each other with cylinder head cover, the return tube that links to each other with oil sump, the outlet pipe that communicates with atmosphere.
The utility model can also adopt following technical measures:
The described suction tude that links to each other with cylinder head cover is a flexible pipe.
The described return tube that links to each other with oil sump is a flexible pipe.
Advantage and the good effect that the utlity model has are: owing on the cylinder head cover of the present utility model deaerator is installed, the suction tude of deaerator is connected with cylinder head cover, return tube is connected with oil sump, outlet pipe communicates with atmosphere, therefore after oil gas separates in separator, machine oil can in time flow back in the oil sump along return tube, avoids producing in separator accumulation, coking.Still can not destroy the structure of separator after permanent the use, not influence its performance; In addition, it is recycling fully to adopt new structure that machine oil is obtained, and has reduced cost; It is small and exquisite, simple that the utility model also has structure, and it is convenient to change, and with original structure certain interchangeability is arranged, and makes things convenient for the maintenance of client to vehicle.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a deaerator structural representation among Fig. 1.
Among the figure: 1, cylinder body; 2, cylinder cap; 3, cylinder head cover; 4, deaerator; 4-1, suction tude; 4-2, return tube; 4-3, outlet pipe; 5, oil sump.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, cylinder body 1 upper end is equipped with cylinder cap 2, and cylinder head cover 3 is installed on the cylinder cap, in the side of cylinder head cover deaerator 4 is installed, and cylinder head cover 3 is communicated with the suction tude 4-1 of deaerator, and suction tude adopts rubber pipe; The oil sump 5 that is positioned at cylinder body 1 lower end is communicated with the return tube 4-2 of deaerator, and return tube adopts rubber pipe, and the outlet pipe 4-3 of deaerator communicates with atmosphere.
User mode of the present utility model is, the high-temperature oil gas that cylinder body 1 is discharged in the running arrives cylinder head cover 3 through cylinder cap 2, high-temperature oil gas with certain flow rate flows to deaerator 4 through the suction tude 4-1 that cylinder head cover 3 is communicated with deaerator 4, and high-temperature oil gas will be made circular movement along deaerator 4 inwalls by certain initial velocity; Machine oil in the oil gas sinks under the effect of centrifugal force and gravity gradually, flowing back to oil sump 5 through deaerator 4 isolated machine oil by return tube 4-2 utilizes once more, gas in the oil gas will be discharged in the atmosphere along outlet pipe 4-3, the effective like this Oil-gas Separation purpose that realized, and the machine oil in the oil gas is fully recycled, saved cost.
Claims (3)
