Background technique

At present, common positive displacement compressor has: reciprocating piston type, rotary-piston type, rotary vane type, list (two) spiral rod type, vortex type, diaphragm type etc.The compressor of these forms causes owing to design and constructional reason: noise, vibrate greatlyyer, poorly sealed, slide plate is easily stuck, defectives such as processing cost, precision height.

Summary of the invention

At the deficiency that prior art exists, purpose of the present invention just be to provide a kind of simple in structure, volume is little, in light weight, good seal, the rotary vane type compressor easily processing and operate steadily.

For achieving the above object, the technical solution adopted in the present invention is:

A kind of rotary vane type compressor comprises cylinder body, rotor, upper end cap, four constituent elements of lower end cap.Rotor is positioned at the eccentric and tangent with it position of cylinder interior, and upper end cap is fixed on cylinder body two ends and sealing mutually with it with lower end cap, is equipped with the bearing that is used for support rotor on it.Rotor subject is cylindrical, offer a groove longitudinally on the side face of outer garden, this groove is the arc surfaced consistent with rotor direction on the cross section, cambered surface one side links to each other with rotor surface, opposite side by revolve longitudinally the lobe axle be hinged with one can be with it to the lobe that revolves of synthetic full circle cylinder, the inboard of groove offers the through hole of certain depth, is equipped with in the through hole to revolve the spring of the outside jack-up of lobe.Be the center of circle with its bearing hole in the mounting groove of lower end cap, the position of revolving the lobe axle on the respective rotor offers one section arc-like rows and goes out the duct, offers the inlet hole that is connected with low pressure area on the mounting groove of lower end cap.Form during rotor rotation and between the inboard wall of cylinder block with the point of contact and revolve zone of high pressure and the low pressure area that lobe is the boundary.

Offer the garden cylindricality mounting groove that is used to be linked on the cylinder body on described upper end cap and the lower end cap.

Rotating shaft one end of described rotor is packed in the bearing of lower end cap, and the other end passes from the upper end cap bearing hole.

All be provided with mounting hole on described upper end cap and the lower end cap, and cylinder body be fastened between the two by nut.

Described rotor one end is provided with keyway and spiral shell button.

The present invention is in when work, rotor with its eccentric tangent cylinder body in when rotating, under the effect of revolving lobe, form volume-variation, thereby finish the process of suctions, compression, discharge, compared with prior art have following outstanding beneficial effect:

1, simple in structure, used component are few, save material;

2, easy processing, processing cost is low;

3, rotor control is discharged, and has replaced expulsion valve;

4, revolve lobe and move around axle, can not be stuck, rate of fault is low;

5, good seal leaks and lacks the delivery pressure height;

6, rotor rotatablely moves, and vibrations and noise are little.

Embodiment

The present invention will be further described in detail below in conjunction with accompanying drawing.

Description of reference numerals is as follows:

1. lower end cap

2. cylinder body

3. rotor

4. inlet hole

5. rotor shaft

6. spring

7. revolve the lobe axle

8. revolve lobe

9. discharge duct

As Fig. 1 to rotary vane type compressor shown in Figure 11, mainly by cylinder body (2), rotor (3), upper end cap (11), (1) four constituent element of lower end cap.Rotor (3) is positioned at the inner eccentric and tangent with it position of cylinder body (2), upper end cap (11) and lower end cap (1) all are provided with mounting hole (10), and by nut cylinder body (2) is fastened between the two and with it mutually the sealing, be equipped with the bearing (12) that is used for support rotor (3) on upper end cap (11) and the lower end cap (1), rotor (3) one ends outwards pass from the hole of upper end cap by bearing (12) and oil sealing (13), traversing through end is provided with keyway (15) and spiral shell button (16), the main body of rotor (3) is cylindrical, offer a groove longitudinally on the side face of outer garden, this groove is on the cross section and the consistent arc surfaced of rotor (3) direction, cambered surface one side links to each other with rotor (3) surface, opposite side is hinged with one and can be with it synthetic full circle cylinder be revolved lobe (8) by revolving lobe axle (7) longitudinally, the inboard of groove offers the through hole of certain depth, and the spring (6) that will revolve the outside jack-up of lobe is installed in the through hole.Going up with its bearing hole at the cylinder body mounting groove (14) of lower end cap (1) is the center of circle, and the position of revolving lobe axle (7) on the respective rotor (3) offers one section arc-like rows and goes out duct (9), and offers and active chamber (A) and the inlet hole (4) that (B) is connected.Form with the point of contact when rotor (3) rotates and between the inboard wall of cylinder block and revolve zone of high pressure (B) and the low pressure area (A) that lobe (8) is the boundary.

As the working principle schematic representation of Figure 12 to a periodic duty process shown in Figure 15.

As shown in figure 12, this moment be circulation of compressor just at first, inlet hole (4) is connected with active chamber (A) with (B), the groove that revolves lobe (8) and rotor (3) side fits like a glove, revolve lobe (8) and rotor (3) and sealed arc-like rows and go out duct (9), played the effect of expulsion valve.

As shown in figure 13, the state of compressor map interlinking 12 continues operation, and rotor (3) turns clockwise, and revolves lobe (8) and outwards opens gradually under the effect of spring (6), and when revolving lobe (8) and seal inlet hole (4), active chamber (B) volume will dwindle gradually, the compression beginning.

As shown in figure 14, the state of compressor map interlinking 13 continues operation, rotor (3) continues rotation, revolving lobe (8) continues outwards to open under the effect of compression pressure, active chamber (B) volume continues to dwindle, and active chamber (A) volume enlarges the formation negative pressure gradually will be compressed thing by inlet hole (4) suction active chamber (A).

As shown in figure 15, the state of compressor map interlinking 14 continues operation, and rotor (3) continues rotation, goes out duct (9) when being connected when rotor recesses goes to arc-like rows, is compressed thing and discharges by discharging duct (9).Rotor (3) continues to go to position shown in Figure 12, finishes a periodic duty process.

Figure 16 shows that another embodiment of compressor, rotor (3) for revolving lobe (8) structure more.
