Abstract
The utility model discloses a brake air condition compressor with an unloading plant and pertains to a vehicle brake equipment field. The technical proposal is that the utility model comprises a cylinder body and a cylinder lid, wherein an intake valve device and an outlet valve device are respectively arranged on the cylinder lid. The upper part of the intake valve device is provided with the unloading plant which comprises a shell fixed on the cylinder lid, an unloading plunger within the shell, wherein the unloading plunger is divided into an upper cavity and a lower cavity, A spring is arranged on the unloading plunger and can press down the intake valve device to open the valve. The upper cavity is connected with the pipeline that is arranged between a vent and an accumulator unit via the pipeline. Thus when the exhaust pressure of the air condition compressor reach a certain degree, the compressed air drives down the unloading plunger to open the valve plate of the intake valve device, thus the air condition compressor is in a state of unloading when rotating. When the pressure within the air storage tank is dropping, the spring goes up against the unloading plunger to leave off the valve plate of the intake valve device, thereby the valve plate returns to the original place and at this time the air condition compressor is in normal operation. The utility model has advantage of that the compressor simplifies the structure, reduce the power consumption and manufacturing cost, improve the reliability and efficiently reduce the occurrence of breakdown.
Description
Technical field
The utility model relates to a kind of air compressor, relates in particular to a kind of braking air compressor that has relief arrangement.
Background technique
The braking of prior art is not provided with special relief arrangement with air compressor, but the pressure regulator valve of the another kind of structural type of adapted, so that when gas holder pressure surpasses specified value, the air compressor relief opening promptly through the straight-through atmosphere of pressure regulator valve, emits compressor air and end gas holder is inflated.After this, when gas holder pressure was reduced to another specified value, pressure regulator valve side made air compressor recover to inflate to gas holder.The air compressor of this structure, its relief arrangement is communicated with pressure regulator valve, and pressure regulator valve is communicated with gas holder, and gas holder is communicated with the outlet valve of air compressor again, so forms a closed-loop path.Therefore, this relief arrangement complex structure, because pipeline is more, power consumption is big, the probability that breaks down is big, so safety reliability is poor.
Summary of the invention
The utility model is at the existing in prior technology shortcoming, simplifies the structure and provide a kind of, has reduced kinetic equation loss, can reduce cost, and has improved reliability, can effectively reduce the technological scheme of the air compressor of rate of breakdown.
The utility model is realized by following technical measures: it mainly comprises cylinder body, cylinder cap is equipped with suction valve device and discharge valve apparatus, be provided with relief arrangement at cylinder cap and above the suction valve device, relief arrangement comprises the housing that is fixed on the cylinder cap, the off-load plunger in the housing, the off-load plunger is divided into epicoele and cavity of resorption with housing, the off-load plunger is provided with spring and air-intake valve plate can be pressed down unlatching, and described epicoele is by the pipeline connection between pipeline and relief opening and the caisson.Drain pressure when air compressor reaches one regularly like this, pressurized air moves down the off-load plunger valve block of suction valve device device is opened, be in unloading condition when air compressor turns round like this, when the pressure in the gas holder descends, spring is with off-load plunger jack-up, make it break away from the valve block of suction valve device, the valve block of suction valve device resets like this, at this moment the air compressor proper functioning.
Set the pressure values of the unlatching of relief arrangement in addition for convenience, the off-load plunger in the relief arrangement housing is provided with pressure-regulating device.By the pressure values in the pressure values control gas holder of control off-load, when the pressure value of meeting the requirements of in the gas holder, the relief arrangement running.
Above-mentioned pressure-regulating device comprises the spring that is sleeved on the plunger rod, is provided with look nut in the lower end of spring, and look nut is screwed on the relief arrangement housing.By the compressed degree of swivel nut control spring, thereby the final highest pressure value that realizes setting in the gas holder starts relief arrangement when being higher than this peak.This regulation structure is simple, and is convenient and practical, and cost is low.
The beneficial effects of the utility model can find out that the utility model simplifies the structure by foregoing description, have reduced kinetic equation loss, can reduce cost, and have improved reliability, can effectively reduce rate of breakdown.
