Definitions

  • the invention relates to a device for transmitting a driving force between two components according to the preamble of claim 1.
  • Such a device is known from DE 33 29 790 A1.
  • a driving force is transmitted in a valve carrier between a first component (driver 15) and a second component (lamella 13) via a cover (flat slide valve 34) which is in engagement with the first component on the one hand and with the second component on the other hand, the first component is slidably guided in a housing and the cover seals the housing.
  • the cover is displaced with the first component by engagement with a part of the first component which projects out of the housing. So that the cover can fulfill its sealing function at any time during this displacement, it must be dimensioned sufficiently in the direction of the displacement axis to cover the housing, in particular its opening required for the protruding part mentioned above, in every position of the first component.
  • the invention is therefore based on the object to improve a device of the type mentioned with simple means such that its space requirement in the direction of the axis of displacement of the first component can be significantly reduced.
  • the invention is suitable for all types of displaceability of the first component; the displaceability can, for example, be straight and / or take place along a curved path.
  • the invention enables a reduction in the relative movements between the cover and the housing and thus a reduction in the corresponding friction work with an increase in the efficiency of the device as a result.
  • the driving force can come from any of the components involved.
  • the invention is suitable for all types of movement of the second component.
  • An example is one translatory movement (displacement) or a pivoting movement to think about an axis of rotation, which can run essentially parallel to the axis of rotation of the lid.
  • the axis of rotation of the cover can in turn be arranged to run essentially transversely to the axis of displacement of the first component.
  • the invention can advantageously be used in a case in which one component is displaceable or movable between two end positions and thereby drives the other component to move or move between two end positions assigned to the end positions mentioned.
  • the first component is designed as a driver of an actuator arranged in the housing for moving the second component.
  • the drive of the second component is important.
  • the second component is designed as a lamellar valve member of a valve formed by this valve member and at least one housing opening.
  • the valve member can be pivoted between two end positions, in one of which it opens (opens) the housing opening and in the other it covers the housing opening (ie closes unless the valve member is lifted from the housing opening, for example by negative pressure transversely to the pivoting direction) ).
  • An embodiment in which the cover does not influence or impair the housing contours results if the cover is sunk in the housing to a flush surface of the housing facing away from the housing with a surface surrounding the cover.
  • This housing surface can be a specially arranged housing surface, for example a countersunk, but also the outer housing surface per se or an inner housing surface.
  • the above-mentioned recessed arrangement of the cover advantageously enables the second component to be guided on the housing surface mentioned and on the side of the cover facing away from the housing.
  • the lid can be rotated in any suitable manner.
  • the cover has at least one lateral surface that is rotationally symmetrical with respect to its axis of rotation and with which it is mounted radially in a lateral surface of the housing that is compatible with it.
  • This outer surface can be the outer outer surface, which determines the transverse dimension of the cover, or an inner outer surface.
  • the housing should also be sealed between the outer surface of the cover and the outer surface of the housing that is compatible with it.
  • the aforementioned lateral surfaces describe at least one circle in the plan.
  • the diameter of the lateral surfaces can be dimensioned such that an opening in the form of a housing slot, in which the first component is guided in the direction of its displacement axis, is arranged within the outline of the lateral surface of the housing, at least approximately Kind of a tendon lies in this floor plan.
  • the housing has a sealing seat enclosing the lateral surface in a plane lying transverse to the axis of rotation of the cover, on which the cover is arranged with a compatible one and arranged transversely to its axis of rotation Sealing seat rests.
  • the seal created in this way precedes the rotatable bearing, not only relieving it of the sealing function, but also protecting it also against influences that originate on the side of the cover facing away from the housing or on the inner or outer surface of the housing assigned to this side of the cover.
  • the outer surface of the cover can show any course.
  • the cover can be designed if its outer lateral surface is rotationally symmetrical to its axis of rotation, that is, depending on the design, has at least one circle as a plan.
  • the embodiment mentioned above with the rotatable bearing upstream seal can be designed to save space by arranging the sealing seats of the cover and housing on a transition surface between the outer lateral surfaces and the lateral surfaces serving to rotatably support the cover.
  • both lateral surfaces can be cylindrical, conical or crowned.
  • the cover-side lateral surface can also be cylindrical, for example, and the housing-side lateral surface can be conical or spherical.
  • sealing seats of the housing and of the cover can also be designed in all suitable mutually compatible ways. In consideration all pairings come with surface or line contact. A separate seal can also be arranged between the sealing seats mentioned.
  • the valve carrier shown has a housing (1) in the form of a plate, in and on which a device for transmitting a driving force between two components (22, 2) is arranged.
  • the first component (22) is the driver of an actuator arranged in the housing (1) and generally designated (8).
  • the first component (22) is slidably guided in the housing (1).
  • the guidance takes place in a (straight) housing slot (7).
  • the housing (1) has an opening (27) through which the first component (22) can be knocked out.
  • the housing slot (7) is covered by a cover (5) in such a way that it protects the housing (1) against influences on the side of the cover (5) facing away from the housing (1) or that side of the cover (5) Side of the housing (1) have their origin seals.
  • the first component (22) has a part (21) protruding from the housing (1), especially from the housing slot (7), which engages with the cover (5).
  • the cover (5) is rotatably mounted in the housing (1), namely about an axis of rotation (6) extending essentially transversely to the displacement axis (double arrow V) of the first component (22), such that, as a result of the engagement between the cover (5) and the first component (22) of a rotation of the cover (5) corresponds to a displacement (V) of the first component (22).
  • FIG. 2 The axis of rotation (6) of the cover (5) is shown in FIG. 2 as the center line of the cover (5), while FIG. 1 only shows its point projection.
  • a lamellar valve member is provided as the second component (2) and is pivotally mounted in the housing (1) about a pivot axis (12) parallel to the axis of rotation (6).
  • the pivot axis (12) is shown in FIG. 1 as the center of an unspecified pivot pin which radially supports the second component (2).
  • the pivoting movement of the second component (2) is indicated by a double arrow (S).
  • the cover (5) engages with the second component (2) on its side facing away from the housing (1).
  • the first component (22) can be displaced between two end positions, which are denoted by (I) or (II) in FIG. 2. When it moves between these end positions, the first component (22) drives the second component (2) between two (swivel) end positions assigned to these end positions in the manner described below.
  • the end position of the second component (2) assigned to the position (I) of the first component (22) is shown in the figures.
  • the second component (2) forms an inlet valve (2, 9) with a housing opening (9), which is the mouth of a housing channel.
  • the second component In its end position assigned to position (I), the second component covers the housing opening (9) and thereby closes the inlet valve (2, 9), unless it is exerted by a force transversely to the pivoting movement, for example as a result of a vacuum, from the housing opening (9) is lifted off. In its end position corresponding to position (II), the second component (2) releases the housing opening (9) and thereby opens the inlet valve (2, 9).
  • the illustration also shows a second housing opening (10) with which the second component (2) forms a further inlet valve (2, 10), for which the determinations just made apply accordingly.
  • the points of engagement between the cover (5) and the first component (22) on the one hand and between the cover (5) and the second component (2) on the other hand are designed so that the components (22 or 2) when transmitting a driving force between the components on the Cover (5) transverse to its axis of rotation (6) essentially no forces, in other words: in can exert essentially no radial forces on the cover (5). This ensures that the drive force is transmitted without jamming between the components.
  • the engagement points in the exemplary embodiment are designed as follows.
  • the cover (5) On its side facing the housing (1), the cover (5) has a guide slot (20) which is essentially directed towards its axis of rotation (6) and in which the part (21) of the first component (21) protruding from the housing (1) 22) is performed.
  • the cover (5) On the other hand, the cover (5) has on its side facing away from the housing (1) a driver (4) which is guided in an elongated guide slot (3) formed in the second component (2) in the longitudinal direction thereof, which longitudinal direction essentially runs transverse to the swivel direction (S).
  • driver and guide slot could also be interchanged to produce the engagement between cover and second component.
  • the cover (5) is sunk in the housing (1) such that its surface facing away from the housing (1) is essentially flush with a housing surface (24) surrounding the cover (5).
  • the surrounding housing surface (24) and the side of the cover (5) facing away from the housing (1) form a coherent surface on which the second component (2) is guided as it moves.
  • the mentioned housing surface (24) is in turn lowered by at least the thickness of the second component (2) compared to the rest of the housing surface on the relevant side. Since the driver (4) of the cover (5) is not thicker than the second component (2), the lowering of the surface (24) means that the device is accommodated in the housing without exceeding the housing dimensions.
  • the housing (1) has an outer surface, which is rotationally symmetrical to the axis of rotation (6), for example produced by countersinking.
  • the cover has a jacket surface (26) that is compatible with this jacket surface. With this he is mounted radially in the lateral surface of the housing (1).
  • the lateral surfaces mentioned have, as rotationally symmetrical surfaces, at least one circle as a plan.
  • the housing slot (7) lies within this floor plan. The diameter of the lateral surfaces is dimensioned such that the guide slot in the plan is at least approximately in the manner of a (circular) chord, ie touches or almost touches the plan in the area of its end faces.
  • the position of the axis of rotation (6) can be varied within the framework of the desired force or path translations between the components, then it can also be used to determine the smallest possible transverse dimension of the cover (5). If, in a manner not shown, the described rotatable mounting, more precisely: the bed joint, the sealing function described above is also transferred, so the minimum possible transverse dimension of the cover (5) is ensured.
  • the rotatable mounting (bearing joint) is relieved of the sealing function.
  • the housing has, in a plane lying transversely to the axis of rotation (6) of the cover (5), a sealing seat, not designated, enclosing the lateral surface, on which the cover (5) with a compatible sealing seat (23) rests.
  • the sealing seats of the housing (1) and cover (5) are enclosed by an outer outer surface, which is rotationally symmetrical to the axis of rotation (6) and compatible with one another, of which that on the cover is designated by (25). Due to the rotationally symmetrical design of this outer lateral surface, the construction with the smallest possible transverse dimension of the cover (5) is achieved in view of the separation of the rotatable bearing and sealing function.
  • the sealing seats are each formed on transition surfaces in the housing (1) and on the cover (5) between the outer circumferential surface (e.g. 25) and the rotatable bearing-serving circumferential surface (e.g. 26).
  • the lateral surfaces mentioned are shown as cylindrical surfaces and the sealing seats mentioned are shown as step surfaces between the cylindrical surfaces. However, these surfaces can also be designed in any other way that ensures the required functions.
  • the described separation of the rotatable bearing and the sealing function also enables, in a manner not shown, that the cover instead of the rotating one
  • the lateral surface (26) has bearing points or surfaces only in a few places on the same circumference.
  • the cover (5) is designed as a disk-shaped body, which is sunk with its entire thickness in the housing (1). This arrangement also serves to accommodate the device in the housing, as already mentioned, without changing the overall dimensions.
  • valve member (13) As shown in FIG. 1, there is another lamellar valve member (13) on the non-lowered area of the housing surface, which forms further inlet valves (11, 13) with housing openings (11) in a manner not described in detail and which forms the second component (2 ) partially covered in the top view.
  • the valve member (13) is omitted for the sake of clarity.
  • the device shown in the exemplary embodiment for transmitting a driving force between two components functions as follows.
  • the first component can be displaced from its end position (I) into its end position (I) by pressurizing the actuator (8) via an unspecified pressure connection and is pushed back into the end position (I) by a return spring (not specified) when the pressure drops.
  • the first component (22) transmits a driving force in the circumferential direction of the cover (5) to the flank of the guide slot (20) in the cover (5), the end (21) of the first component (22) in the guide slot ( 20) slides.
  • the driver (4) of the cover (5) exerts a peripheral force on the flank of the guide slot (3) on the second component (2) about its pivot axis (12), the driver (4) simultaneously in the guide slot ( 3) slides.
  • the force and displacement ratio between the first component (22) and the second component ( 2) can be varied.
  • the first component (22) and the second component (2) move in the same direction; this is because seen from the pivot axis (12), the points of engagement between the two components (22, 2) and cover (5) are arranged on this side of the axis of rotation (6).
