Abstract
The utility model belongs to a breathing device for an air compressor, which is particularly suitable for the miniature and small air compressors the air displacement of which is smaller than or equal to 10 cubic meters per minute. The utility model comprises a breather valve and a vent pipe. The breather valve is installed on a back cover of a crankcase, an air inlet port is arranged on a first level air inlet chamber, and the vent pipe is connected between the air inlet port and the breather valve. The utility model has the advantages of low engine oil consumption and no pollution, and can enhance the air suction efficiency of the compressor to a certain extent.
Description
The utility model belongs to a kind of breathing equipment of air compressor, and it is particularly suitable for little, the mini air compressor use of air displacement smaller or equal to 10 cubic metres of per minutes.
Because can not seal fully between the piston ring of compressor and the cylinder, air compressor always has portion gas to enter in the crankcase because of leakage when pressurized air, form back pressure, therefore, the technician is provided with an inhalation valve usually on the crankcase bonnet.Existing inhalation valve is made up of valve body, steel ball, end cap, and back pressure gas is discharged by inhalation valve, directly enters air.Because compressor adopts splash system lubrication, the bent axle of compressor is when high speed rotating again, and the pin of buying oil certainly will stir the lubricant oil in the crankcase, and under action of centrifugal force, lubricant oil is thrown out of from spindle, forms mist of oil.Mist of oil will enter inhalation valve by back pressure gas in crankcase, under the damping function of steel ball, the part mist of oil is separated from the gas in inhalation valve, and lubricant oil flows back to bonnet, enters crankcase again, but still have the part mist of oil to discharge with back pressure gas, enter air.This shows that there is following defective in existing inhalation valve: 1, increased consumption of lubricating oil, strengthened user cost; 2, befouling environment; 3, reduce the exhaust efficiency of compressor.Along with the increasing of the discharge capacity and the exhaust pressure of compressor, above defective is more obvious.
In view of this, the purpose of this utility model is that the defective that overcomes prior art provides a kind of low consumption of lubricating oil, non-environmental-pollution, and improved little, the mini air compressor breathing equipment of the gettering efficiency of compressor to a certain extent.
The technical solution of the utility model is: little, mini air compressor breathing equipment comprises inhalation valve, inhalation valve is installed on the crankcase bonnet, it also comprises breathing pipe, has inlet hole on air compressor one-level air-inlet cavity, is connected breathing pipe between inlet hole and inhalation valve.
The utility model is owing to be connected breathing pipe between inhalation valve and one-level air-inlet cavity, therefore, the back pressure gas of discharging from valve body enters the one-level air-inlet cavity with mist of oil by the breathing pipe transporting, has stopped environmental pollution, has improved the gettering efficiency of compressor.Owing to after mist of oil enters the one-level air-inlet cavity, promptly enter next compression cycle, therefore reduced the machine oil loss.
Accompanying drawing 1 is a V-type air compressor breathing equipment schematic representation.
Accompanying drawing 2 is a Z type air compressor breathing equipment schematic representation.
Accompanying drawing 3 is a model utility partial cutaway diagrammatic sketch.
Below in conjunction with accompanying drawing the utility model is elaborated.
V-type air compressor breathing equipment embodiment.Little, mini air compressor comprises the inhalation valve of being made up of valve body 2, steel ball 3, end cap pipe 4, and breathing pipe 6 is used for the ventilation elbow 8 that breathing pipe 6 is installed.Steel ball 3 places valve body 2, and the suction port of valve body 2 is by the air outlet of the crankcase bonnet 1 that is threaded, and end cap pipe 4 is T-shape, and one by being threadedly connected to the air outlet of valve body 2, and two is connected to breathing pipe 6 by gland nut 5 in addition.As Fig. 3, have inlet hole 9 on the one-level air-inlet cavity cylinder head stopper 7, ventilation elbow 8 one ends are connected with suction port 9 by screw thread, and the other end is connected with breathing pipe 6 by gland nut 5.
As Fig. 2, the utility model is equally applicable to Z type air compressor, because this type air compressor is vertical, so end cap pipe 4 is a straight tube-like.
Equally, the utility model is applicable to that also different model such as W type, different external form, air displacement use smaller or equal to little, the mini air compressor of 10 cubic metres of per minutes.
