Abstract
The utility model relates to a plunger type quantitative dispenser, which is used for filling lubricant grease in a lubrication system. The utility model comprises a casing, a plunger sleeve in the casing, a guide sleeve, a control plunger in the plunger sleeve, and a grease discharge plunger in the guide sleeve, wherein the upper end of the control plunger is sheathed with a spring, the upper part of which is sheathed on a quantitative rod that can move relatively to the control plunger until contacting the control plunger, and the travel range of the quantitative rod is pre-arranged according to grease needed to be discharged. The grease discharge plunger is in slide fit with the guide sleeve which is connected with the casing by screw threads. The casing, the plunger sleeve, the guide sleeve, the control plunger, and the grease discharge plunger are communicated with each other by oil paths, and are communicated with a grease inlet and a grease outlet. Through the displacement of the control plunger and the grease discharge plunger, the oil paths are opened or closed. Grease is not supplied through the expansion and contraction of a sealing ring. Grease output can be arranged as required through the regulation of the travel range of the quantitative rod. The utility model has the advantages of reliable working performance and accurate quantitative grease supply.

Embodiment
Shown in accompanying drawing, a kind of plunger-type quantitative distributor of the present utility model comprises control plunger 12 and the interior oil extraction plunger 5 of guide pin bushing in plunger bushing 17, guide pin bushing 3 and the plunger bushing in housing 1, the housing; In the plunger bushing periphery axial groove 11 that runs through two ends is arranged, have the annular groove 16 of center hole 13, control plunger periphery of radial hole 14 and control plunger and annular groove to be connected on this groove with cross-drilled hole 15 between center hole; On plunger bushing, there is a radial hole 19 to communicate in addition with the oil outlet 20 of housing, oil inlet hole 18 on control plunger lower end and housing connects, control plunger upper end is with spring 10, the top cover set amount bar 4 of this spring, this quantitative bar can relatively move with the control plunger, until both contacts, its stroke need set in advance by oil drain quantity; This quantitative bar overcoat oil extraction plunger 5, oil extraction plunger and guide pin bushing are slidingly matched, guide pin bushing and housing scyewed joint, this connection screw thread place at guide pin bushing has axial groove 8, there is aperture 7 to communicate on this groove with oil extraction plunger upper end portion, the groove lower end is connected with circular groove 9, is connected with the axial groove 11 of plunger bushing periphery by circular groove, and seal ring 6 is housed on the guide pin bushing upper periphery;
For making cleaning, on guide pin bushing 3 tops, be provided with dust-proof cover 2, dust-proof cover fixes by screw and housing;
Said quantitative bar 4 overcoat oil extraction plungers 5, quantitatively the end face of bar and the spacing of oil extraction plunger are adjustable;
The oil outlet 20 that communicates with radial hole 19 on the said housing can be offered two by different direction, blocks with plug 21 for wherein no one.
This distributor can be combined into a column of dispensers by a plurality of being superimposed.
Working principle of the present utility model is: when oil inlet hole 18 feeds pressure oil, control plunger 12 the effect lower compression spring 10 of pressure oil and on move, cut off being communicated with of cross-drilled hole 15 on radial hole 14 and the control plunger and center hole 13 gradually, on continuing, moves the control plunger, oil inlet hole 18 connects with radial hole 14, pressure oil is by controlling radially aperture 14 of plunger underpart, axial groove 11, circular groove 9, axial groove 8, aperture 7, to oil extraction plunger 5 upper end portions, pressure oil makes the oil extraction plunger drive quantitative bar 4 and moves down, pressure spring 10, with the fluid of preserving between quantitative bar 4 and control plunger 12, the radial hole 19 on plunger bushing transfers to lubricating point by oil outlet 20; When quantitative bar 4 props up the set point of control plunger upper end portion and it is further depressed when moving, the control plunger has blocked radial hole 14, and the oil-feed path is cut off, and the oil extraction operating mode stops.
When the oil pressure at oil inlet hole 18 places reduces because of off-load, the control plunger further moves down under the effect of spring force, connect until radial hole 14 and cross-drilled hole 15 and the center hole 13 controlled on the plunger, oil extraction this moment plunger drives quantitative bar and moves up under the effect of spring force, the fluid that makes oil extraction plunger upper end portion is through aperture 7, axial groove 8, circular groove 9, axial groove 11, radial hole 14, annular groove 16, cross-drilled hole 15, center hole 13 enters store oil between quantitative bar 4 and the control plunger 12, prop up the guide pin bushing set point until the oil extraction plunger, on move end, the store oil operating mode finishes, and finishes a circulation.
