Definitions
- the invention relates to a Schwenkkolbenverdränger with a Displacer housing, in which an approximately cylindrical receiving space for an approximately cylindrical, smaller in outer diameter and mounted eccentrically to the receiving space on an eccentric drive Swivel piston is provided between its outer wall and the inner wall of the receiving space is an approximately sickle-shaped Interspace forms, which by one, between one in the housing located inlet opening and an outlet opening arranged Divider divided into a pressure chamber and a suction chamber is, on the one hand with the housing and on the other connected to the pivot piston, outer and inner Attachment points of the divider in the circumferential direction of the Swivel piston offset from each other and are where the divider is made of bendable material.
- the divider also made of a flexible Material, such as a thin spring metal strip or a spring strip package, or of an elastomeric material, For example, reinforced rubber, or as one of such Materials composite construction can be made can, with the divider always a uniform thickness having.
- DE 26 28 365 A1 that the separating web hinged at its bead-shaped attachment points rotatably in associated recesses of the rotary piston on the one hand and the housing is mounted on the other, closes the DE 26 28 365 A1 does not mean that the u.a. also made of elastic or flexible materials or materials Trennsteg the elasticity of the material used at least almost maintained.
- a so-called rotary piston compressor a compressor housing with an approximately cylindrical receiving space Has. In the receiving space is also about cylindrical, provided in the outer diameter of smaller rolling piston, the mounted eccentrically to the receiving space on an eccentric drive is.
- the previously known rotary compressor has a metal Link on the one hand on the rolling piston and on the other hinged to the peripheral space bounding the receiving space is held.
- the connecting member which is the suction chamber from the pressure chamber separates, consists of a bolt-shaped linkage members provided circular arc piece, which is when rolling of the rolling piston inserts tightly into a recess in the housing wall, causing a gentle rolling overflow of the rolling piston is achieved. While the outlet slot with the pressure side permanently communicates, controls the link at his Pivoting the inlet slot of this otherwise valveless Single compressor.
- a Schwenkkolbenverdränger is known in which the between the outer peripheral piston wall and the Inner wall of the receiving space remaining crescent-shaped gap is divided by a divider, which consists of a elastic material.
- This divider which is about radial is oriented to the oscillating piston, is in the rolling movement the swing piston on the inner wall of the receiving space cyclically compressed and stretched. Due to these stretching and compression loads the elastic material of the divider becomes so claims that connected to the pivot piston divider only a comparatively short life is granted.
- the achievement of this task is in the Schwenkkolbenverdränger of the type mentioned in particular in that the divider near its two attachment ends Bending sections and inbetween a more rigid Intermediate section has.
- the also made of bendable material manufactured divider of the rotary piston displacer according to the invention has an intermediate section compared to the bending portions provided near the attachment ends designed more rigid and therefore against compression of the Trennstegs is relatively insensitive.
- the inventive design of the divider allows that this divider the relatively large tensile and especially the Can absorb compression forces by the at a fast-running swivel piston compressor on the divider acting mass forces can arise.
- the Schwenkkolbenverdränger invention has none metal parts rubbing against each other, the abrasive media should not be suspended or an additional Lubrication required in the area of the receiving space. Since the one hand with the housing and on the other hand with the Swivel piston connected divider between its outer and inner attachment point runs approximately helically, is this divider when rolling the pivot piston only one Bending stress, but not additional stretching and compression loads exposed. Because the divider, made only of bendable Material consist, but not necessarily made of elastic material must be prepared during the operation of the invention Schwenkkolbenverdrfiters only comparatively small Loads is exposed, the invention is characterized Schwenkkolbenverdränger in this respect by a long life and a versatile usability. The long life is further increased by the fact that the flexible divider no is subjected to elastic deformation, so that one with additional energy expenditure and with increased warming Connected flexing work on the divider can be avoided.
- the outer attachment point of Trennstegs on the housing between the inlet opening and the Outlet opening and the inner attachment point in Circumferential direction offset to an outer Attachment point is arranged on the rotary piston that the Divider in abutment position on the inner wall of the receiving space covers the inlet or outlet.
- the divider becomes during the rolling movements of the rotary piston so sealing pressed against the inlet or outlet opening that a performance-reducing return flow of the pumped medium avoided can be.
- a preferred embodiment which is characterized by a particularly high work performance, provides that the outer Attachment point of the divider to the housing between the Inlet opening and the outlet opening close to the outlet opening and the inner attachment point of the divider on the Swivel piston next to the inlet opening, the outlet opening turned away, are arranged.
- a hinged tilting of the divider during the Rolling movements of the rotary piston is facilitated when the Divider at its attachment bead-like, preferably in cross-section has approximately round or rounded formations and if in the housing and the rotary piston to matching mounting recesses are provided.
- Schwenkkolbenverdrnatureers does not necessarily have to be made of elastic material, but can also consist of solely flexible material can the divider, for example made of flexible plastic and / or an elastomer and / or spring steel.
- the two bending sections of the divider have a smaller cross-section than the intermediate section.
- the Schwenkkolbenverdrnatureers invention must the divider the torque of the rotary piston not only as Traction, but also can absorb as a compressive force.
- This can by a corresponding, for example, thickened shape of the divider and / or about one incorporated into the divider Reinforcement can be achieved.
- the intermediate section the divider a gain, preferably a Reinforcing insert to increase the compressive stiffness in the Compound level has between the attachment ends.
- the housing and / or the rotary piston in the circumferential course of the Trennstegs recesses for at least partially receiving the Have separating web.
- a short circuit between pressure and suction chamber can be effectively avoid if laterally next to the swinging piston between at least one of its side walls and the housing or a drive shaft guide at least one circumferentially closed seal is provided. It can as seals ring seals and / or bellows seals be provided.
- Another refinement embodiment according to the invention is that the Schwenkkolbenverdränger part of a Compressed air motor and that at least two axially juxtaposed Schwenkkolbenverdränger with in Rotation direction preferably offset by 180 ° swivel piston are provided. Are the swing pistons offset by 180 ° arranged, then at the 12 o'clock position a Oscillating piston an overflow of compressed air between inlet and outlet opening prevented. This is a startup of the engine from any position.
- FIG. 1 is different versions 1, 2, 3 a Schwenkkolbenverdrnatureers shown.
- the swivel piston displacer 1, 2 and 3 have a displacement housing 4, the at least one approximately cylindrical receiving space 5 bounded.
- In the at least one receiving space 5 is an approximately cylindrical and in the outer diameter slightly smaller swing piston. 6 intended.
- the pivoting piston 6 of the at least one Receiving space 5 is mounted on an eccentric drive 7.
- the one end of the bridge with the rotary piston. 6 connected divider 8 is with its other web end between a located in the displacer housing 4 inlet port 11 and an outlet opening 12 held on the displacer housing 4.
- the swivel piston displacers 1, 2, 3 shown here have no metal parts rubbing against each other, the abrassiven Media should not be suspended or an additional Lubrication required in the area of the receiving space. Since the one hand with the displacer 4 and on the other with the swing piston 6 connected divider 8 between his outer and inner attachment point approximately spirally runs, this divider is 8 when rolling the Swivel piston 6 exposed to only one bending stress. There the flexible divider 8 no elastic deformation is exposed, with an additional energy expenditure and increased heating associated flexing work on the divider 8 avoided.
- the illustrated here Schwenkkolbenverdränger 1, 2, 3 are therefore characterized by a long life and their versatile usability.
- the outer one is Attachment point of the divider 8 on the displacer 4 between the inlet opening 11 and the outlet opening 12 and the inner attachment point on the rotary piston 6 in the circumferential direction arranged at a distance offset from one another such that the Trennsteg 8 in abutment position on the inner wall of the Recording space covers the inlet opening 11.
- the divider 8 can be fixed to the outside of the rotary piston 6 be formed. Here, however, the divider 8 is both on Displacer 4 as well as on the pivot piston 6 releasably held.
- the divider 8 points to his Fastening bead-like, preferably in cross section approximately round or rounded projections 15 which in the housing 4 and on the pivot piston 6 in matching mounting recesses are held.
- the receiving space is in the Figures 1 to 3 hermetically illustrated liquid pump tightly formed. This is laterally next to the pivot piston. 6 on the drive-side side wall and an adjacent Drive shaft guide 13 a circumferentially closed Seal 16 provided here as a bellows seal is designed.
- the Schwenkkolbenverdränger 2 shown in Figure 4 is as Compressor formed.
- an exhaust valve 20 is provided.
- the Exhaust valve 20 has a centrally held membrane disk on which the outlet openings 12 on the displacer 4 close.
- the trained as a compressor Swivel piston displacer 2 for example, when pumping no bellows seal from air 16.
- Such a bellows seal 16 is only required for a compressor 2, for example toxic, expensive or radioactive gases has pumped.
- the side surfaces of the Swivel piston 6 with not visible in Figure 4 sealing rings be sealed.
- a Schwenkkolbenverdränger 3 is shown, the here serves as a compressed air motor. To start the engine off ensure each pivot position out, has the designed as a compressed air motor Schwenkkolbenverdränger 3 two offset by 180 ° pivoting piston 6, which is also at the 12 o'clock position a rotary piston 6 an overflow of compressed air between inlet and outlet ports 11, 12 prevent.
- the Schwenkkolbenverdränger shown here and in particular the liquid pump 1 according to the figures 1 to 3 can also as reversible, i. Direction of rotation variable pump designed be. Since the divider 8 in such a reversible Liquid pump 1, the torque of the rotary piston 6 is not only as a tensile force, but also as a compressive force, is an at least partially reinforcing the dividing web. 8 appropriate. For all here shown Schwenkkolbenverdrängern must the divider 8 beyond the Pressure differences between the pressure chamber 9 and the suction chamber 10th be able to record. Also, there are corresponding reinforcements and support options advantageous.
- Such Reinforcement can, for example, by the in Figure 6 shown shaping of the divider 8 done, in which the two bending sections of the divider a smaller one Have cross section as the thickened intermediate portion 22. Additionally or alternatively, it may also be appropriate if the divider 8 in the region of its intermediate portion 22 a Armiereinlage 21, with which the Pressure stiffness in the connection plane between the Can increase attachment ends of the divider 8 (Fig.7).
