Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description.Obviously, described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Below
Description only actually at least one exemplary embodiment be it is illustrative, never as to the present invention and its application or make
Any restrictions.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figures 1 to 6, the embodiment provides a kind of spacers, and spacer is for being arranged in the first gas
Between cylinder and the second cylinder, spacer includes ontology 10, through-hole 20 and Oil Guide chamber 30.Wherein, ontology 10 has and is oppositely arranged
First end face and second end face, first end face and second end face are respectively used to be cooperatively connected with the first cylinder and the second cylinder.It is logical
Hole 20 is arranged on ontology 10, and through-hole 20 is for wearing crankshaft.Oil Guide chamber 30 is arranged on ontology 10, Oil Guide chamber 30 and through-hole 20
Connection.
Using the technical solution of the present embodiment, Oil Guide chamber 30 is set on the ontology 10 of spacer, and by Oil Guide chamber 30 with
Through-hole 20 on ontology 10 is connected to, and at work, the lubricating oil between crankshaft and through-hole 20 can be flow to leads such compressor
In oil pocket 30, the relatively low lubricating oil of temperature can be to cold in the first cylinder or the second cylinder by heat transfer in Oil Guide chamber 30
Matchmaker cools down, and so as to reduce the temperature of refrigerant, improves the efficiency of compressor.
Specifically, Oil Guide chamber 30 is arranged in the suction hole of close first cylinder of ontology 10 and/or close to the second cylinder
The position of suction hole.Cylinder generates suction superheat in the suction chamber of the position of suction hole and close suction hole at work
Problem.The suction hole close to the first cylinder by the way that ontology 10 is arranged in Oil Guide chamber 30 or the suction hole close to second cylinder
Position can prevent suction superheat by the cooling effect of lubricating oil.The temperature of refrigerant can be reduced in this way, to improve compression
The volumetric efficiency and efficiency of machine.Oil Guide chamber 30 is arranged at the same time close to the suction hole of the suction hole of the first cylinder and the second cylinder
Position, two cylinder suction superheats can be prevented simultaneously.
As shown in Figure 1, Oil Guide chamber 30 is sector structure.Sector structure is set by Oil Guide chamber 30, Oil Guide chamber can be increased
30 volume, so that the more lubricating oil of storage in Oil Guide chamber 30, and can match with the shape of the intake region of cylinder,
So as to improve the cooling effect to refrigerant.Lubricating oil in the present embodiment can be understood as the refrigeration oil in compressor.?
In the present embodiment, 180 ° to 220 ° can be set by the angle between two end faces of sector structure, with the air-breathing with cylinder
Region matches.
In the present embodiment, the entrance of Oil Guide chamber 30 is connected to through-hole 20, the outlet of Oil Guide chamber 30 and the outside of ontology 10
Connection.Such setting can be such that lubricating oil flows in Oil Guide chamber 30, to reinforce heat exchange effect, improve to refrigerant and the first gas
The cooling effect of cylinder or the second cylinder.
As shown in Fig. 2, spacer further includes first passage 40, first passage 40 is arranged on ontology 10, and Oil Guide chamber 30 is logical
First passage 40 is crossed to be connected to through-hole 20.It, can be convenient for being guided to lubricating oil, so that lubricating oil by the way that first passage 40 is arranged
Smoothly flow therein Oil Guide chamber 30.
First passage 40 can be connected to the external of ontology 10, can not also be connected to the external of ontology 10.In this implementation
In example, first passage 40 includes first entrance 41, first outlet 42 and second outlet 43.Wherein, first entrance 41 and through-hole 20
Connection, first outlet 42 are located at the lateral surface of ontology 10, and second outlet 43 is led between first entrance 41 and first outlet 42
Oil pocket 30 is connected to second outlet 43.Being arranged such can make the lubricating oil into first passage 40 that can both be flowed into Oil Guide chamber 30
It is interior, and the outside of ontology 10 can be flowed out to, so as to reinforce the flowing of lubricating oil, improve heat transfer effect.
As shown in Figure 1, Oil Guide chamber 30 and first passage 40 are arranged at intervals on ontology 10, spacer further includes second channel
50, second channel 50 be arranged on ontology 10, the outlet of second channel 50 is connected to Oil Guide chamber 30, the entrance of second channel 50 and
First passage 40 is connected to.By the way that second channel 50 is arranged, the lubricating oil for entering first passage 40 can be shunted, make one
Lubricating oil of sharing in the benefit enters Oil Guide chamber 30, outside or other positions of another part outflow of lubrication oil to ontology 10.
As shown in Fig. 2, spacer further includes third channel 60, third channel 60 is arranged on ontology 10, third channel 60
Entrance be connected to first passage 40, the outlet of third channel 60 is located in first end face and/or second end face, third channel 60
Sliding vane groove of the outlet for cylinder be connected to.It, can will be between the through-hole and crankshaft of spacer by the way that third channel 60 is arranged
Lubricating oil be introduced into the sliding vane groove of cylinder, to be lubricated to the slide plate in sliding vane groove.Cylinder herein can be first
Cylinder or the second cylinder can also be the first cylinder and the second cylinder.
For original compressor, when the liquid level of lubricating oil is lower than slide plate, lubricating oil cannot moisten slide plate
It is sliding, it is prone to wear the components such as slide plate.Technical solution through this embodiment, even if the liquid level of lubricating oil is lower than slide plate,
In the case where the rotation of crankshaft drives, the lubricating oil between through-hole and crankshaft can sequentially pass through first passage 40 and third channel 60 enters

On end face and second end face, third channel 60 be it is multiple, multiple third channels 60 are set along the extending direction interval of first passage 40
It sets.When the first cylinder and the second cylinder are according to identical location arrangements, can by two of third channel 60 outlets respectively to
Lubricating oil is provided in the sliding vane groove of first cylinder and the second cylinder, to guarantee that the slide plate in the first cylinder and the second cylinder can
Obtain good lubrication.
As shown in Figure 1, ontology 10 is ring structure, first passage 40 is radially extended along ontology 10,60 edge of third channel
Ontology 10 it is axially extending.Such setting can be in order to the processing of first passage 40 and third channel 60, to reduce spacer
Manufacturing cost.
In the present embodiment, spacer further includes fourth lane 70, and fourth lane 70 is arranged on ontology 10, fourth lane
70 entrance and the outlet of Oil Guide chamber 30, the outlet of fourth lane 70 are located at the lateral surface of ontology 10.Pass through setting the 4th
Channel 70 can reinforce the guiding function to lubricating oil, consequently facilitating the flowing of lubricating oil, improves the cooling effect to refrigerant.
It specifically, can be by angle of the Oil Guide chamber 30 between the end face of fourth lane 70 and the axis of first passage 40
It is set as 180 ° to 220 °, meanwhile, by folder of the Oil Guide chamber 30 between the end face of first passage 40 and the axis of first passage
The value at angle is arranged smaller, to improve the volume of Oil Guide chamber 30, so that Oil Guide chamber 30 stores more lubricating oil, and then improves
To the cooling effect of refrigerant.
Spacer, which can be set, to be an integral structure, and may be set to be split type structure.In the present embodiment, ontology 10
Including first partition 11 and second partition 12, first partition 11 and second partition 12 are cooperatively connected.Wherein, first end face is located at the
