Definitions
- the invention relates to a device for conveying, preferably with pressure, liquid media or for conveying and / or compressing gaseous media with a housing with a pressure and a suction connection, in which housing an eccentrically rotatable to the housing mounted rotor is arranged, in which at least one slider is slidably held in the radial direction, which runs sealingly along the inner wall of the housing and which is guided along a guide, the line of contact of the rotor with the inner wall of the housing between the suction and the pressure connection.
- a device of this type namely a pump, has been e.g. known from U.S. Patent 3,001,482.
- slides are provided with rollers which are guided in a groove-shaped guide with considerable play in order to avoid jamming of the rollers.
- the aim of the invention is to avoid these disadvantages and to propose a device of the type mentioned in the introduction, in which a play-free guidance of the slides is ensured without the risk of the slides becoming jammed.
- the center paths of the rolling elements associated with the guideways have a diametrically constant distance from the center of the drive shaft of the rotor, which results in a play-free guidance of the slide with at least one approximately elliptical guideway .
- Another object of the invention is to propose a work machine or an engine.
- the housing has at least two separate chambers, in each of which one rotor is located, and that the housing runs along a guide and is guided along a guide, the line of contact of the rotor with the inner wall of the housing lying between the inlet and the outlet is arranged with a slide, the runners being connected to one another in a rotationally fixed manner and the slide being controlled by two guide tracks arranged on the inside of an attachment, on which rolling elements of the slide roll, each slide being supported on both guide tracks and an outlet of the one chamber is connected to the inlet of the other chamber with the interposition of a control element.
- the proposed measures ensure reliable guidance of the slide. By guiding the slide with two rolling bodies rolling on different guideways, an exact and practically play-free guidance is ensured, the risk of jamming also being avoided. This also results in very little wear, since the rolling elements roll on free tracks and cannot grind their end faces against other walls, as is unavoidable when guiding rolls in grooves and leads to increased wear.
- the center paths of the rolling elements assigned to the guideways have a diametrically constant distance with respect to the center of the drive shaft of the rotor, which results in a play-free guidance of the slides with at least approximately elliptical Guideway results.
- control member is formed by a hollow cylinder provided with slots, the interior of which can be alternately connected via the slots to the connecting line or the second chamber.
- control member the interior of the control member being a prechamber forms in which the mixture which has flowed in under pressure can be kept under pressure until the connection to the second chamber is opened, even if the pressure in the connecting line between the two chambers has already decreased due to a change in the position of the rotor and thus of the slide ⁇ is sunken. All that is required for this is a corresponding arrangement of the slots and a corresponding control of the hollow cylinder having them.
- the rotor arranged in the second chamber has a depression on its lateral surface, which is arranged close to a guide for the slide passing through the rotor.
- the volume that can be supplied to the second chamber can be increased in a simple manner without the position of the slide having to be changed in the direction of the outlet of the second chamber, the slide being used when the mixture flows into the second chamber available volume is limited.
- the slide can be exposed to the force of the expanding gas or mixture for a large part of the travel of the slide during one revolution of the rotor.
- the runners of the two chambers are connected to one another via a coupling, in which the two coupling halves can be adjusted and locked in their mutual position, the two coupling halves preferably being provided with a toothing which is engaged with each other.
- Fig. 1 shows a longitudinal section
- Fig. 2 shows a cross section through an inventive
- Fig. 3 shows a longitudinal section through an inventive
- Fig. 5 shows a cross section along line VV of Fig. 3 through the second chamber
- Fig. 6 shows schematically the kinematics of the rolling process of the support body.
- the drive shaft 3 is eccentrically mounted in the housing 5 or on bearings held on the plates thereof.
- the housing 5 has an inlet 5a and an outlet connection 5b for the liquid medium which is preferably to be conveyed under pressure or the gaseous medium which is to be conveyed and / or compressed. Operating modes of e.g. as a gas or liquid pump, compressor or the like are therefore possible.
- This end shield is designed as a control ring 1 and has on the inside of a tubular extension in two different planes perpendicular to the drive shaft 3 arranged guideways la, lb.
- a hollow rotor 4 is arranged, which is arranged centrally on the drive shaft 3 and from this anget ⁇ o .. (> *:. Is The annular wall of the hollow rotor 4 provided me Amsterdamin slot 7, which is penetrated by the slide 2. .
- the slider 2 has an elongated slot 9 which is penetrated by the drive shaft 3, which in the area of the slider 2 has flats 10 which can slide along the walls of the elongated slot 9 of the slider 2 and between them with only slight play intervention.
- the slide 2 By controlling the slide 2 by means of the two rolling bodies 2a, 2b which - as explained in more detail in connection with FIG. 6 - roll on the two guideways la, lb, at least one of which has the shape of an ellipse , the desired distance of the end face 11 of the slide from the inner wall 12 of the housing can be maintained, by means of which the wear of the slide can be kept correspondingly low.
- the course of the two guide tracks 1a, 1b is dependent on the shape of the inner wall 12 of the housing 5 and the eccentricities of the drive shaft in relation to the house 5, and depending on the size of the hollow rotor 4, the size of which determines the measure of the delivery rate or the performance of the pump.
- the housing 105 of the engine according to FIGS. 3 to 5 has an inlet and an outlet connection 109, 110 for the mixture to be compressed.
- the bearing plates 151, 152, 153, 154 are provided with control rings 101 and, on the inside of a tubular extension, have guide tracks 101a, 101b arranged in two different planes perpendicular to the drive shaft 103.
- each hollow rotor 104 is arranged, which is arranged centrally on the drive shaft 103 and is driven by the latter.
- the annular wall of each hollow runner 104 is provided with a slot 155 through which the slide 102 passes.
- the slider 102 has an elongated slot, which is penetrated by the drive shaft 103, which has flats in the area of the slider 102, which can slide along the walls of the elongated slot of the slider 102 and intervene between them with only slight play.
- Rollers 116 are also held on each slide 102, two of which each roll on a different guideway 101a, 101b.
- the desired distance of the end face of the slide from the inner wall of the housing can be achieved ⁇ ses 105 are observed, through which the wear of the slide 102 can be kept correspondingly low.
- the course of the two guideways 101a, 101b depends on the shape of the inner wall of the housing 105 and the eccentricities of the drive shaft in relation to the housing 105, and on the size of the hollow rotor 104, the size of which determines the measure of the performance of the machine .
- the diametrical distance between the two guideways 101a, 101b from one another always remains the same, thereby ensuring exact guiding of the slides 102, by absorbing the centrifugal forces that occur during operation, which would lead to the slider being pressed against the inner wall of the housing, which would result in a correspondingly high level of wear.
- the drive shaft 103 is subdivided by a clutch 115, the coupling halves of which are non-rotatably connected to the two parts of the drive shaft 103 and are provided with a toothing in mutual engagement.
- the chamber 160 has an outlet 162 next to the inlet 109 of the housing 105, which outlet is connected to the second chamber 161 via a connecting line 107.
- a hollow cylinder 106 is arranged between the connecting line 107 and the inlet 171 of the second chamber 161, the cylindrical wall of which is penetrated by two slots 172, 173.
- this hollow cylinder 106 can be rotated by means of a cam 111 and a linkage 112.
- the slide 102 arranged in the chamber 161 is only partially indicated for the sake of clarity, with the omission of the rolling elements 116.
- the arrangement and design correspond to that of the slide arranged in the chamber 160, cf. Fig. 5.
- the cam controller 111, 112 reverses the hollow cylinder 106 and the slot 173 coincides brought with the inlet 171 so that the pressurized mixture can flow.
- the rotor 104 arranged in the chamber 182 is in a position in which its depression 117 arranged in the lateral surface is opposite the inlet 171, which opens essentially tangentially into the chamber 182.
- a spark plug 108 is arranged next to the inlet 171 and ignites the mixture.
- the associated expansion of the fuel gas drives the rotor 104 in the direction of the arrow 175, the gas in the space 182 being expelled via the outlet 110 of the housing 105.
- the rotor 104 of the chamber 160 is driven via the drive shafts and the clutch 115, which in connection with the slide valve 102 draws in and compresses the mixture.
- the compression of the mixture can be increased or decreased.
- the compression can also be increased so far that the mixture ignites by itself, so that under certain circumstances. the spark plug 108 can be dispensed with.
- FIG. 6 shows the creation of the geometrical shapes of the guideways la, 101a and lb for the exemplary embodiment according to FIG. 1 and that according to FIG. 2.
- the shape of the guideway 1b, 101b, of which approximately half is depicted, must be determined in accordance with the conditions which should prevail at the point of contact 52 between slide 2, 102 and housing 5, 105.
- Both the center path lb ', 101b' of the rollers 2b, 116 and the guideway 1b, 101b will generally deviate only slightly or not at all from a circular path around the housing center point 51.
- a deviation from the circular path can e.g. to compensate for different centrifugal forces which occur due to variable slide positions and would inevitably lead to different deformations on the supporting parts (rollers 2b, 116) and thus a grinding of the slide 2, 102 at the contact point 51.
- the second guideway la, 101a which is intended to ensure a play-free slide movement, is due to the guideway lb, 101b or its center path lb, 101b and the constant center-to-center distance of the rollers 2a and 2b or 116 or the eccentricity e is defined as the distance between the shaft center 31 and the housing center 51.
- the center path la 'of the rollers 2a can be understood starting from the center path 1b', as the set of all points which are diametrically opposed to each other with respect to the shaft center 31.
- the guide track la, 101a of which only about half that is shown in FIG. 6, which corresponds to the half of the guide track 1b, 101b also shown, then results as an equidistant with the distance corresponding to the roller body radius r to Center line la ', 101a'.
