Abstract
A non-eccentric elliptic rotor compressor is a novel compressor put forward to aim at the defect that an eccentric quality exists in a rotating rotor compressor and thus vibrations and noises are caused. The novel compressor changes the eccentric shaft and sleeve in the rotating rotor compressor for a central shaft and an elliptic rotor that has an interference fit with the central shaft. (or the central shaft is integrated with the elliptic rotor.) The elliptic rotor has a clearance fit with an air cylinder and forms a sealed primitive volume with sliding vanes and the bilateral cylinder covers. The primitive volume has periodic changes in the wake of the rotation of the central shaft and the elliptic rotor, thereby achieving the induction, compression and exhaust of gases.
Description
The utility model relates to a kind of compressor, particularly a kind of rotator type displacement type compressor.
Existing rolling rotor type compressor mainly reaches the eccentric crankshaft that matches with sleeve by the sleeve in slide plate, cylinder, the cylinder (claiming rotor or rolling piston again) and forms, motor drives sleeve by bent axle and do plane motion in cylinder, finishes the cyclic process of air-breathing, compression, exhaust.The characteristics of this compressor are that rotor is a round structure, and become arranged off-centre with cylinder.Such structure and layout make this type compressor have advantages such as simple in structure, easy processing, but make it have some shortcomings too, and there is eccentric mass exactly in wherein topmost shortcoming and causes vibration and noise.
The purpose of this utility model is to solve it to have eccentric mass and cause vibrating and the shortcoming of noise when keeping advantages such as existing rolling rotor type compressor is simple in structure, easy processing.
The purpose of this utility model is achieved in that elliptical rotor compressor without acceptance of persons is the elliptic rotor (central shaft also can be processed into one with elliptic rotor) that changes its eccentric shaft and sleeve into be not with eccentric mass central shaft and become interference fit with it on the basis of rolling rotor type compressor, elliptic rotor becomes Spielpassung with cylinder, and form the element volume of sealing with slide plate and both sides cylinder cap, this element volume produces periodic variation along with the rotation of central shaft and elliptic rotor, thereby realizes suction, compression and the exhaust of gas.Gap between elliptic rotor and the cylinder can reduce by the formation of lubricant film, thereby reduces the gas leakage between the element volume.
As seen the employing of said structure and arrangement can continue not only to keep that existing rolling rotor type compressor is simple in structure, the advantage of easy processing, does not also have the vibration that causes owing to eccentric mass and the shortcoming of noise simultaneously.
Fig. 1 is a longitudinal section of the present utility model.
Fig. 2 is a sectional elevation of the present utility model.
Among the figure, the 1st, compression case, the 2nd, motor, the 3rd, central shaft, the 4th, upper cylinder cover, the 5th, elliptic rotor, the 6th, bolt, the 7th, oil nozzle, the 8th, following cylinder cap, the 9th, spring, the 10th, slide plate, the 11st, outlet valve, the 12nd, relief opening, the 13rd, cylinder, the 14th, intakeport.
Rotated around the center in cylinder by prime mover such as motor or internal combustion engine drive elliptic rotor, slide plate is reciprocating under the acting in conjunction of elliptic rotor and spring, simultaneously the cavity in the cylinder is divided into air aspiration cavity and exhaust cavity.Open intakeport and relief opening on the cylinder, when elliptic rotor when cylinder axis rotates, air aspiration cavity and exhaust cavity periodically communicate with intakeport and relief opening and produce cyclically-varying on the volume, thereby constantly realize suction, compression and the exhaust process of gas.
Claims (3)
1. elliptical rotor compressor without acceptance of persons, belong to a kind of displacement type compressor, form by central shaft, cylinder, outlet valve, elliptic rotor, slide plate, spring and both sides cylinder cap, it is characterized in that: rotor be shaped as ellipse and central shaft, elliptic rotor and cylinder are arranged concentric.
2. elliptical rotor compressor without acceptance of persons according to claim 1 is characterized in that: central shaft becomes interference fit or is processed into one with elliptic rotor, elliptic rotor becomes Spielpassung with cylinder.
