Now be described with reference to the accompanying drawings as follows with preferred embodiment:

Please refer to Fig. 1, Fig. 2, Fig. 3, the utility model distributor 1 is established a plurality of mounting hole 11 for installation, and it is made up of an oil inlet pipe 3, three group oil outlet groups 2 and three group cycle assignment loop sets 4 at least at least; This oil inlet pipe 3 be provided with screw thread and not penetration hole for Lubricant feeding machine input lubricant oil, this be dutiful join on loop sets 4, the oil outlet group 2 or under stride across oil inlet pipe 3 and be divided into the both sides.

Please refer to Fig. 2, Fig. 3, the utility model quantitative lubricating distributor, wherein, this cycle assignment loop sets 4 is: a straight hole 40 that strides across oil inlet pipe 3 and run through, its left and right sides is established right screw 41, left screw 42 respectively, two right screws 41 again, 41A, left screw 42, establish parting on the right side of inclination between 42B respectively and join through hole 43, part on the left side and join through hole 431 and make two groups of straight holes 40,40A communicates; Straight hole 40 is established a through hole 30 and is communicated in oil inlet pipe 3 again, also establish right oil outlet 21, the left oil outlet 22 that a right port 31 and left port 32 are communicated in following explanation respectively in the appropriate location, two ends, straight hole 40 is also installed a dispensing piston 44 and with screw thread stopple 410 screw locks;

Please refer to Fig. 1, Fig. 5, this dispensing piston 44 is cylinders of multistage different-diameter, and wherein path 440 stretches out screw thread stopple 410 and outside being exposed to, twice path 441 less than straight hole 40 to hold the fixed capacity lubricating fluid;

Please refer to Fig. 3, Fig. 4, the utility model quantitative lubricating distributor, wherein, this oil outlet group 2 is: be parallel to straight hole 40 belows, its left and right sides is established the not right oil outlet 21 and the left oil outlet 22 of penetration hole and screw thread respectively; Two right oil outlets 21 and two 22 of left oil outlets are established right intercommunicating pore 23, a left connection hole 231 that tilts respectively respectively makes two groups of holes communicate; The right port 31 that right again oil outlet 21 is established Vertical direction communicates in straight hole 40; The left port 32 that left side oil outlet 22 is established Vertical direction communicates in straight hole 40;

Because the utility model can expand oil outlet group 2 and cycle assignment loop sets 4 becomes many groups, as five, six, seven groups,,, and its hole, loop is identical, for convenience of explanation, second group its both sides of straight hole numbering 40A right screw numbering 41A, left screw 42A, second oil outlet that straight hole 40A is beneath named second right oil outlet 21A, second left oil outlet 22A, and its inclined hole is right intercommunicating pore 23A, left connection hole 231A; Second through hole 30A of second straight hole 40A of name, second right port 31A, second left port 32A, be assemblied in second dispensing piston name 44A in second straight hole 40A, the inclined hole name on second right screw 41A next door parts on the right side joins through hole 43A, and the inclined hole name on second left screw 42A next door parts on the left side joins through hole 481A.The 3rd group straight hole numbering 40B, right screw 41B is named in its both sides, left screw 42B, the 3rd oil outlet that straight hole 40B is beneath named the 3rd right oil outlet 21B, the 3rd left oil outlet 22B, and its inclined hole is right intercommunicating pore 23B, left connection hole 231B; Name the 3rd the through hole 30B of the 3rd straight hole 40B, the 3rd right port 31B, the 3rd left port 32B, the 3rd dispensing piston 44B, the inclined hole name on the 3rd right screw 41B next door parts on the right side joins through hole 43B, and the inclined hole name on the 3rd left screw 42B next door parts on the left side joins through hole 431B; By that analogy, for the ease of processing, right port 31, left port 32 and balanced loop 45 are with stopple 12 screw locks by external boring back; Each right screw 41,41A, 41B, 41C left side screw 42,42A, 42B, 42C etc. are all with screw thread stopple screw lock in addition.

Please refer to Fig. 2, hole, four groups of loops begins to take shape, and afterwards, parts on the right side and allocates oilhole 47 into and first right screw 41 is communicated with hole, balanced loop 45 and allot oilhole 47C and communicate with last straight hole 40C through parting on the left side; Part on the left side and allocate oilhole 46 into and make first left spiral shell also 42 communicate with hole, balanced loop 45 and allot oilhole 46C and communicate with the opposite side of last straight hole 40C through parting on the right side.When dispensing piston during in the neutral position, part and allot oilhole 47C, part on the right side the position of allotting oilhole 46C on the left side and be the path approximately on the neutral position that is positioned at dispensing piston 44, the position of the left and right distribution through hole on the straight hole is to be positioned on the big footpath of dispensing piston.

The utility model figure is shown with four right oil outlet 31A, B, and C and four left oil outlet 22A, B, C amounts to eight oil outlets, expands with the same practice more to have more oilhole, has six oil outlets at least; The composition in hole, the above-mentioned loop of mat, lubricant oil is flowed into by oil inlet pipe 3, please refer to Fig. 2, via through holes 30 flows into and is distributed in first group of straight hole 40 with the space of the inferior path 441 of dispensing piston 44 and to the right promotion dispensing piston 44, after moving the certain oil mass of supply, through hole 30 is blocked and fuel feeding no longer in the big footpath of dispensing piston 44, lubricant oil flows into the right screw 41A that right piston hole 43 enters second group, promoting dispensing piston 44A is moved to the left, making oil flow into right port 31A enters second group of right oil outlet 21A and flows out, the flow of lubricant output is quantitatively to form quantitatively as aforesaid space, because though right intercommunicating pore 23A communicates, but the hole is little and resistance is big, can not flow to right intercommunicating pore 23A through right oil outlet 21B, unless right oil outlet 21A is with screw thread stopple screw lock; 44A is moved to the left because of dispensing piston, through hole 30A is not blocked in its big footpath and fuel feeding promotes dispensing piston 44A in the space of the inferior path 441A of second group of straight hole 40A and dispensing piston 44A and to the right, after moving the certain oil mass of supply, through hole 30A is blocked and fuel feeding no longer in the big footpath of dispensing piston 44A, oil flows into to part on the right side joins the right screw 41B that through hole 43A enters the 3rd group, promote dispensing piston 44B and be moved to the left, make oil flow into right port 31B and enter the 3rd group of right oil outlet 21B and flow out, by that analogy; Lubricant oil flows out the 4th group of right oil outlet 21C, be after the last oil outlet in the right flows out, oil is flowed out by the 4th group of through hole 30C, flow into the 4th group of straight hole 40C and dispensing piston 44C inferior path 441C the space and promote dispensing piston 44 to the right, oil is allotted oilhole 46C and is entered this hole, balanced loop 45 and communicate and allocate oilhole 46 into and enter first left screw 42 in parting on the left side through parting on the right side, promotes dispensing piston 44 and is moved to the left, foregoing symmetry action, oil is flowed out in regular turn by left oil outlet, no longer describe in detail.Please refer to Fig. 5, the utility model also can install limit switch 5 additional, and the path length 440 time of contact of itself and piston judges as circuit loop whether piston blocks so that control signal to be provided.
