Abstract

The utility model relates to a compressor, comprising a housing, a piston, and a connecting shaft, wherein the piston is arranged inside the housing; one end of the connecting shaft is connected with the piston, the other end of the connecting rod protrudes to the external of the housing, and the piston is elliptic. The compressor is favorable for improving the motor efficiency and reducing the bearing load.

Description

A kind of compressor

Technical field

The utility model relates to a kind of compressor.

Background technique

Traditional compressor all is to adopt eccentric shaft to rotate to change volume of cylinder, such as rolling piston compressor, scroll compressor etc., increased the merit loss of eccentric shaft, also keep away the bump of unavoidable eccentric shaft to rolling piston or moving scroll, easily compressor is caused damage and galloping when moving, noise and vibrations are all bigger, and bearing load is big.Relatively excessive fuel consumption of the compressor that has, as the screw rod machine, the comparison difficulty is done in the pressure of centrifugal compressor and miniaturization.

The model utility content

In order to solve the technical problem described in the background technique, the utility model provides a kind of compressor.

Technical solution of the present utility model is: the utility model is a kind of compressor, comprise housing, be arranged on piston, coupling shaft in the housing, described coupling shaft one end is connected with piston, and the other end stretches out outside the housing, its special way is that described piston is oval-shaped.

Above-mentioned housing is provided with slideway, is provided with slide plate, spring in the slideway, described slideway along housing shaft to setting, its opening along housing radially inwards, closed end extends to outside the housing; Described slide plate one end is connected with the slideway closed end by spring, and the other end and piston periphery wall contact.

Above-mentioned housing is provided with pore.

Above-mentioned pore is two, is separately positioned on the both sides of slideway.

Above-mentioned slideway along housing shaft to length and piston along housing shaft to length adapt.

The utility model is owing to adopt oval piston, and it is at the oval column Piston Compression gas twice that rotates a circle with motor reel, and suction, exhaust process are continuous, thereby make exhaust airstream more steady.Owing to do not adopt the eccentric shaft rotation, but adopt motor reel to drive the piston rotation, so compressor operation is steady, balance is good, change in torque is even by coupling shaft, help improving motor efficiency, reduce bearing load, noise and vibrations are all smaller, and are few with oil mass.In addition, this compressor arrangement is simple, and easily worn part is few, and production is more prone to, and especially compact apparatus is than the easier processing of other compressor, thereby helps the development of miniaturization.In addition, this compressor can be used for multiple media such as transporting water, has the effect of pump.

Description of drawings

Fig. 1 is the utility model structural representation.

Fig. 2 is a working principle schematic representation of the present utility model.

Embodiment

Referring to Fig. 1, the utility model comprises housing 1, is arranged on piston 2, coupling shaft 3 in the housing, and described coupling shaft 3 one ends are connected with piston 2, and the other end stretches out outside the housing 1; Described piston 2 is oval-shaped; Described housing 1 is provided with slideway 4, first pore 5, second pore 8, and described first pore 5, second pore 8 are separately positioned on the both sides of slideway; Be provided with slide plate 6, spring 7 in the slideway, described slideway 4 axially is provided with along housing 1, its opening along housing radially inwards, closed end extends to outside the housing 1; Described slide plate 6 one ends are connected by spring 7 and slideway 4 closed ends are inner, and the other end and piston 2 periphery walls contact; Described slideway 4 along the axial length of housing 1 and piston 2 along housing shaft to length adapt; Described first pore 5, second pore 8 are separately positioned on the both sides of slideway.

Referring to Fig. 2, during the utility model work, adopting motor reel to drive coupling shaft 3 drive pistons 2 rotates in cylinder, slide plate 6 is along with the rotation of piston 2 is done straight line motion along sliding 4 roads, slide plate 6 upper ends are headed on by row's spring 7 and slide plate 6 lower ends are remained with piston 2 outer surfaces contact, slide plate 6 is divided into air inlet on one side to piston 2 like this, and on one side by compression exhaust, air-breathing, exhaust is continuous.

State A: when the G of the major axis wall of piston 2 end was in the positive lower end of slide plate 6, the piston suction cylinder had just begun air inlet;

State B: when piston 2 was rotated counterclockwise several angle, piston 2 suction cylinders were air-breathing by pore 8, and the major axis wall of piston 2 the other ends is along cylinder slip, exhaust casing pressurized gas, by pore 5 exhausts;

State C: when piston 2 is rotated counterclockwise 180 when spending, at this moment the G end that is initially located in the transverse wall under the slide plate 6 is in the position relative with slide plate 6, the air-breathing end of piston 2 suction cylinders this moment, and exhaust casing finishes by pore 5 exhausts;

State D: when piston 2 continues to be rotated counterclockwise, piston 2 major axis wall G end slides along cylinder, and exhaust casing continues pressurized gas;

State E: when piston 2 is rotated counterclockwise 360 when spending, piston major axis wall G end gets back to initial position and slide plate 6 contacts, and the exhaust casing exhaust finishes, and has finished piston cycle like this one time;

State F: piston 2 continues to be rotated counterclockwise, and exhaust casing begins pressurized gas;

State A: the exhaust casing exhaust is finished, thereby finishes gas circulation one time.
