Definitions
- the invention relates to a progressive distributor with three or more control pistons, each of which can be displaced in a housing bore of a distributor housing, each of which delivers a specific quantity of lubricant via a respective front outlet, which is guided via one of two annular grooves in the housing bore of the respective previous control piston the lubricant supplied under pressure through a housing inlet is pressed alternately into its two end positions in the associated housing bore, the control pistons being controlled successively by the lubricant due to the two annular grooves each such that the next control piston can only be displaced by the lubricant when the piston movement of the preceding control piston is completely or almost completed, the housing bores being connected to the inlet via a central bore, one channel each having an annular groove in the respective housing bore of the previous Existing control piston connects to the end face of the respective housing bore of the subsequent control piston, with the exception of a control piston with an annular groove and end face lying on the same side, but with a control piston with an annular groove and end face lying on
- Such a progressive distributor is known from DE 34 05 690 C2. To equip such a progressive distributor with additional functions and To make new applications usable, especially where machines with very small quantities are to be lubricated or where individual lubrication points are to be supplied frequently, but others, for example, can only be supplied daily, weekly or monthly, there is provision for a connecting channel for the respective end faces at least one housing bore, but not all housing bores, each connected to one end face of the bore of an additional cylinder, in which an additional piston is arranged so that it can move back and forth between two stops, at least one piston having to deliver against an outlet pressure which is higher is than the outlet pressure against which the additional piston works, and an overflow valve or a check valve with back pressure is assigned to the corresponding outlets for the generation of the higher outlet pressure.
- the additional pistons can have at least one circumferential groove which only releases an outlet of a piston in the two end positions of the additional piston.
- the respective piston to whose housing bore the additional cylinder is connected, is pushed from one side to the other by acting on one end face, not only the amount of lubricant displaced by the opposite end face of this piston is released from the outlet assigned to this piston, but also by moving the additional piston from its one end position to the opposite end position, such an additional amount of lubricant that corresponds to the free volume of the additional cylinder.
- the displacement cylinder of the individual pistons stops until the entire content of the additional cylinder is emptied, since at least one of these additional pistons would have to move against an outlet pressure that is higher than the outlet pressure that the additional piston takes into account, taking into account the frictional losses has to overcome.
- the additional piston blocks the required outlet for the continuation of the Shifting cycle of the pistons until the additional piston has been shifted from one end position to the other end position and its circumferential groove releases the necessary outlet for the continuation of the shifting cycle.
- the first solution variant has the advantage that the piston can be changed continuously.
- the second variant of the solution has the advantage that it works reliably under all pressure conditions, since an increased back pressure at at least two opposite outlets of a piston is not important.
- the progressive distributor acts with the one additional cylinder as a hydraulic timing element, the time delay for the continuation of the displacement cycle being determinable or determined by the volume of the additional cylinder.
- the object of the present invention is to propose a progressive distributor, from the entire or at least several outlets of which different lubricant volumes can be dispensed with little design effort and safe operation.
- the displacement resistance of the respective metering piston is also advantageously less than the displacement resistance of the control piston assigned to it.
- a determinant of the displacement resistance of the metering piston is its end face, which is subjected to lubricant pressure, and consequently also the cross section of the bores in which the metering pistons can be displaced.
- the displacement resistance of the respective metering piston can be set by means of an O-ring arrangement and / or by fitting it into its bores.
- a structurally advantageous arrangement of the invented progressive distributor is obtained when the respective metering piston is parallel to the control piston assigned to it and on the side of the distributor housing assigned to the inlet, except for a control piston which is closest to the inlet and its metering piston most distant from the inlet.
- stops are arranged on an end face of the distributor housing immediately adjacent to the outlet openings of the associated outlet.
- every second outlet, every second assigned stop and each assigned housing bore for the control pistons are each arranged in one of three rows in such a way that the associated distributor housings, outlets and housing bores for the control pistons are immediately adjacent to each other.
- a check valve can be assigned to the outlet openings of the outlets.
- Fig. 1 shows a schematic section of an embodiment of a progressive distributor implementing the invention
- Fig. 2 shows schematically the view of an end face of the distributor housing.
- FIG. 1 relates to a progressive distributor with a distributor housing G, in which four control pistons SA to SD are fed into four housing bores A to D through a central bore M through the inlet E, for example from a pump (not shown) Lubricant can be moved back and forth.
- the housing bores A to D and the control pistons SA to SD are assigned eight (four on each side) outlets A1 to A8.
- Each control piston SA to SD has two annular grooves R at an axial distance from one another.
- the respective end faces of the housing bores A to D are in flow connection via channels K1 to K8 with the annular groove R of the corresponding control pistons SA to SD of the respective previous housing bores A to D.
- the area of the annular groove R and the end face of the subsequent housing bore D lie on the same side of the) central longitudinal plane (perpendicular to the plane of the drawing, from top to bottom / running).
- the housing bore D of the lowest ⁇ control piston SD is in the area of the annular groove R via the channels K1 and K2; however, in each case with the end face of the housing bore A of the uppermost control piston SA which is opposite with respect to the above-mentioned central longitudinal plane.
- the outlets A1 to A8 are each guided through the housing bore A to D and the annular groove R of the preceding control spool SA to SD.
- the housing bores A to D are all connected to the inlet E via the center bore M.
- control pistons SA to SD under the influence of the supplied lubricant on one end side and by releasing a certain lubricant volume VSA to VSD, alternately into the two end positions in their housing bore A through one of the outlets A1 to A8 on the other side until D is pressed.
- the next control piston SA to SD can only be shifted by the lubricant after the piston movement of the previous control piston SA to SD has been completely or almost completed.
- a connecting channel V1 to V8 connects the respective end faces of the housing bores A to D with one end face of the respectively assigned bore BA to BD with two end stops AS1 to AS8, at least one of which is axially adjustable and / or interchangeable.
- one of the metering pistons BA to BD can be moved back and forth by the lubricant between the stops AS1 to AS8.
- the displacement resistance of the respective metering piston DA to DD assigned to a control piston SA to SD is smaller than the displacement resistance of the respective subsequent control piston SA to SD.
- the displacement resistance of the respective metering piston DA to DD is smaller than the displacement resistance of the control piston SA to SD assigned to it.
- the displacement resistance of the respective metering pistons DA to DD is carried out in the illustrated case by fitting into the associated bore BA to BD, the respective metering piston DA to DD having a larger end face than the respectively associated control piston SA to SD.
- the displacement resistance can also be set by means of an O-ring arrangement on the respective metering pistons DA to DD.
- the respective metering piston DA to DD is provided axially parallel to the control piston SA to SD assigned to it and on the side of the distributor housing assigned to the inlet E, except for a control piston SA which is closest to the inlet E and its metering piston DA farthest from inlet E.
- each second outlet A1 to A8, every second assigned stop AS1 to AS8 and each opening of the assigned housing bores A to D for the control pistons SA to SD are each in one of three rows in opposite end faces of the distributor housing G. arranged in such a way that the mutually assigned outlets A1 to A8, stops AS1 to AS8 and housing bores A to D for the control pistons SA to SD are located directly adjacent to one another in a user-friendly manner.
- a check valve RV1 to RV8 can be assigned to the outlet openings of the outlets A1 to A8.
- lubricant is introduced into the central bore M via the inlet E, it reaches the right end face via the right annular groove R of the control piston SA and the channel K8 of the control piston SB and via the connecting channel V8 onto the right end face of the metering piston DB, which are consequently driven to the left in their respective bores B and BB.
- the displaced volume of lubricant VSB or VDB is due to the connecting channel V7 via the channel K7 and the left annular groove R of the control piston SA on the Outlet A7 delivered. It can be seen that the lubricant volume VDB, which can be displaced by the dosing piston DB, is determined by the changeable axial position of the stop AS7 and is therefore variable.
- an adjustable stop can also be provided for the metering pistons DA to DD on the right-hand side of the bores BA to BD in the drawing, in order to provide a variable displaced lubricant volume on this side as well.
