Embodiment
Fig. 2 shows the variable-displacement swash-plate-type compressor according to the utility model one embodiment.This kind variable-displacement swash-plate-type compressor comprises a front case 1, a cylinder body 2 and a rear case 4.Front case 1 has sealed the front end of cylinder body 2, and it and cylinder body 2 inside have formed an inside and have been provided with the wobbler chamber of wobbler 7, and have the several pistons hole in the cylinder body 2.Rear case 4 has air aspiration cavity and exhaust cavity, and the control valve parts are housed on it, and it is bonded on the rear end of cylinder body 2 by valve plate 3.Cylinder body 2 and front case 1 have supported a live axle 5 by main shaft bearing 13, and this live axle 5 can be around a rotational.Be fixed with a drive plate 6 (rotor) on the live axle 5, it is indoor that this drive plate 6 is positioned at wobbler.In addition, a wobbler 7 is installed on the live axle 5 by its center hole.This swash plate 7 and above-mentioned drive plate 6 are linked into linkage by drive pin, and link to each other with piston in being installed in piston hole by crawler shoe, like this, piston just can its upper dead center and lower dead centre between reciprocating rhythmically, promptly realize air-breathing, the exhaust process of compressor.Simultaneously, linkage can change the inclination angle of wobbler within the specific limits, promptly realizes the displacement variation process of compressor.
In order to improve the lubrication circumstances of compressor under bad working environments, on the wall of wobbler chamber, be provided with some oil suction grooves 10 especially.These oil suction grooves 10 can axially be provided with, and as shown in Figure 2, oil suction groove 10 is preferably parallel with live axle 5.When compressor is installed in the equipment such as automotive air-conditioning system, oil suction groove 10 preferably be positioned at live axle 5 directly over, thereby the nucleus movement mechanism of being convenient to make oil suction groove 10 isolated lubricant oil from refrigeration agent drop in compressor under action of gravity is lubricated.Be preferably in addition, oil suction groove 10 is formed by a taper concave surface, and this taper concave surface is more shallow near the front end place.Simultaneously, the front-end face of front case 1 is connected by an arc surface with the joint of sidewall.Like this, under the synergy of the arc surface of front case 1 and taper concave surface, can make a part of lubricant oil by a main shaft bearing in specific passage 15 (referring to Fig. 5) the lubricate compressors front case 1 13 and axle envelope parts 14.Oil suction groove 10 can directly be molded into from the blank of front case and cylinder body, and its quantity can be set as required, the preferable equally distributed oil suction groove 10 of wall that is provided with 6 to 8 around the wobbler chamber.
In addition, for forward thrust bearing 12, front case 1 interior bearing and the axle that further improves compressor seals the lubricated of parts 14, can on front case 1 end face of wobbler chamber, leakproof oil gluten plate 11 be set.These leakproof oil gluten plates 11 extend along front-end face.In illustrated embodiment, be provided with two leakproof oil gluten plates 11, but also can select to be provided with the gusset of other quantity.
For the indoor lubricating oil splash of wobbler is assigned in the moving parts, on swash plate 7, be provided with some teats 9,9 '.As shown in the figure, the teat 9 on the swash plate 7 is arranged near drive pin 16 joints, and teat 9 preferably can extend near upper dead center.
When the compressor in the present embodiment uses, even under the situation that the flow of the refrigeration agent of carrying lubricant oil secretly of working under the high speed float amount operating mode reduces, rely on the structure of oil suction groove 10, leakproof oil gluten plate 11 and teat 9 in the wobbler chamber, can supply with the lubricant oil of collecting fully by the moving element in compressor, thereby improve the reliability of variable-displacement swash-plate-type compressor.
Those skilled in the art are understandable that it only is exemplary more than describing, and under the prerequisite that does not break away from the utility model scope, the foregoing description also can be made various distortion.For example, the shape of oil suction groove 10 is not limited only to the taper concave surface, also can adopt the shape of cylinder concave surface.Need be understood that although the utility model is that example is described with the variable-displacement swash-plate-type compressor, this technological scheme also can be applicable to the fixed displacement swash-plate-type compressor.These all will be included within the scope of appended claims.
