Background technology
When compressed air container is filled, piston air compressor is switched to free-runing operation.Protected in this pressure pipeline
Holding pressure.Room is also turned on to be pulled in single cylinder piston air compressor.Piston from lower dead center to top dead centre when moving
Indoor air is connected in compression, and the air through overcompression is pushed back when piston is moved from top dead centre to lower dead center again,
So as to which from flow losses, energy need not be expended in free-runing operation.Connection room is bigger, the surge pressure that maximum possible occurs
It is smaller.Size if switch on room is for example just equal with discharge capacity, then surge pressure when piston is positioned at top dead centre is piston
Twice of minimum pressure during positioned at lower dead center.For double-piston or many piston compressors, each cylinder passes through during free-runing operation
Connect room to be connected with each other, so as to not need energy substantially equally.Such piston air compressor the disadvantage is that, as stopping
Returning the diaphragm valve of valve has certain leakage current, and the leakage current is provided with Liter Per Minute and also referred to as leaked.Due to leakage, pressure
Contracting air can be flowed into the cylinder of piston air compressor from pressure pipeline.Very high pressure can be reached during compression.Due to height
Pressure, compressed air flows through between cylinder and piston and reaches compressor housing, and the oil lubrication of piston compressor also is located at compressor
In housing.For the reason for environmental protection, air must be pumped through the internal combustion engine of commercial car, so as to avoid to containing profit
The air of lubricating oil aggravates the burden of environment.If the internal combustion engine of commercial car has turbocharger, the air meeting containing lubricating oil
Cause the accelerated ageing of turbocharger.
At present, Patent No. CN101680446B Chinese patent discloses a kind of piston air compressor, and the piston is empty
Air compressor includes suction chamber and the connection room separated with suction chamber, is provided with according to the present invention from the gas for connecting room to suction chamber
Road.The problem of piston type air compressor of this structure solves leakage to a certain extent, but structure is complex, and dissipate
Hot inconvenience.
