Description
Technical field
The present invention relates to the fluid supply apparatus of compressor, in more detail, relate to having and be installed as the fixedly fluid supply apparatus of the rotary compressor of the oil pipe of the fixed groove of the oil feeder of fuel feeding of friction part.
Background technique
In general, rotary compressor comes compression refrigerant without the rotor in the centrifugal force rotary cylinder, but by with the rolling piston of the rotation interlock that is installed in bent axle lower eccentric portion, along the inner peripheral surface corotation of cylinder and the machine that transfers suction, compression refrigerant certainly.
As shown in Figure 1, closed rotary compressor by inside form airtight containing space seal container (10), be installed in mechanism portion (20) in the seal container (10), be installed in the seal container (10) and drive by the mechanism portion (20) that connects and the compression mechanical part (30) of compression refrigerant and constitute for the oily supply unit (40) of the oil inside offering of seal container (10).
Seal container (10) is by forming the opening portion of opening, the vessel (11) that the bottom, side is provided with suction port (1) respectively at upside and downside, upside opening portion at seal container (10) inserts the last side cover (12) that definite part is installed and the position is formed with exhaust port (4) in the central, and inserts following side cover (13) formation that definite part is installed in the open lower side portion of seal container (10).
At seal container (10) suction port (1) the refrigerant intake channel (2) that connects the internal flow refrigerant is installed, refrigerant intake channel (2) connects the liquid container (3) of a side.
Mechanism portion (20) is to constitute by being fixed on the inner stator (21) of seal container (10) and being installed in stator (21) inboard and carrying out rotor rotated (22).
Compression mechanical part (30) is by being pressed into the running shaft (31) that the inside that is installed in rotor (22) and bottom are formed with eccentric part (31a), inside accommodate eccentric part (31a) and with bolt in conjunction with the upper bearing (32) and the lower bearing (33) of supporting rotating shaft and be installed in the cylinder (35) of seal container (10) inside, inside links to each other with the eccentric part that is formed on running shaft (31) one sides (31a), the rolling piston (36) that the outside joins with the inner face of cylinder (35) and carries out corotation and rotation with eccentric part (31a) rotation, and cylinder (35) inner space is separated into high-voltage section and low voltage section and constitutes at the blade (not shown) that is installed on the cylinder (35) of radially doing straight reciprocating motion of cylinder (35) in rolling piston (36) outside sliding contact.
And, on certain position of upper bearing (32), be formed with the exhaust port (32a) of the refrigerant of discharging compression, the pressure that compression refrigerant is installed on the exhaust port (32a) reaches the expulsion valve (not shown) that certain value could be discharged when above, is equipped with above the upper bearing (32) and reduces the silencing apparatus (37) of discharging noise.
Oil supply unit (40) comprising: a certain amount of oil (41) that accumulates in seal container (10) bottom, from a side of the bottom of running shaft (31) to its side terminal connect running shaft (31) the oily stream (42) that is formed centrally, its bottom surface of inlet side that has hat-shaped and be installed in oily stream (42) is formed with the oil pipe (43) of oily inflow entrance (43a) again, is installed in the inner lower side of oily stream (42) and oil pipe (43) adjacency and oil is passed the oil feeder with propeller cavitation shape (44) of upper lateral part.
Give the closed rotary compressor supply power of above-mentioned formation, the interaction of stator (21) and rotor (22) rotation running shaft (31) then, the rotation according to the eccentric part (31a) of a side that is formed on running shaft (31) makes the rolling piston (36) that contacts with blade (not shown) be rotated in cylinder (35) inside again.Flowing into internal compression that the refrigerant of the low-temp low-pressure of compressor (3) is drawn into cylinder (35) by intake channel (2) suction port (1) by above-mentioned rotation becomes the state of High Temperature High Pressure.
Wash expulsion valve (not shown) open and discharge by exhaust port (32a) at the refrigerant of the High Temperature High Pressure of cylinder (35) compression, the refrigerant of discharge is through the inside of baffler (38) and seal container (10), exhaust port (4) discharge by being formed on side cover (12) again.
When rotary compressor was done to run well, the oil feeder (44) that links with running shaft (31) was rotated, and the oil (41) that accumulates in seal container (10) bottom is by ostium (43a) inflow of oil pipe (44) and by oily stream (42) guiding rising; The oil that rises by oily stream (42) supplies near and each friction part of cylinder (35), and help cylinder (35) is rotated smoothly and compresses.
But, in the aforesaid rotary compressor with pre-structure, in order to force to move oil (41) oil feeder (44) that is rotated (31) support and interlock is pressed into the inner structure that becomes to fix of oily stream (42), therefore, after using the long period, because of its supporting portion oil feeder (44) that fluffs can break away from the mounting point, but the generation part damage can produce the problem that oil is supplied with decreased performance again.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide the structure of the oil feeder of the fluid supply apparatus that improve to support rotary compressor prevent to turn round in oil feeder break away from the mounting point and sustain damage in order to avoid reduces the fluid supply apparatus of the rotary compressor of oil supply performance.
The formation of invention
In order to achieve the above object, the fluid supply apparatus of rotary compressor provided by the invention comprises: the seal container of lubricant oil is gathered in the bottom surface that forms suction port and exhaust port, be installed in the inside of seal container and according to the compression mechanical part of the rotation compression refrigerant of running shaft, give the connecting interior of rotating shaft and have the oily stream of branch of friction part supplying lubricating oil of compression mechanical part at length direction, be installed in the inside of oily stream and will accumulate in the oil feeder that the oil of seal container bottom surface upwards provides, and be installed in and have the fixedly oil pipe of the fixed groove of oil feeder when oil that the oily stream entrance part that forms on the running shaft and guiding accumulate in the seal container bottom surface flows into.
Above-mentioned oil pipe has hat-shaped, is formed with the fixing depression certain depth of oil feeder bi-side and the fixed groove that prolongs to the bottom surface direction of inserting on the bi-side in the opening portion of the oily stream of fixing insertion, and its bottom surface has oily ostium.
Form the mounting structure that is inserted into again behind the fixing side end that inserts oil feeder of fixed groove that the opening portion side at oil pipe forms in the oily stream according to the fluid supply apparatus of aforesaid rotary compressor of the present invention, can prevent that in use oil feeder breaks away from the mounting point, so the life-span that prolongs product is arranged and prevent that oil from supplying with performance low and improve the effect of product image.
