Description

The invention relates to an air dryer housing according to the preamble of claim 1 and a cylinder head housing according to the preamble of claim 3 and a corresponding housing system with the air dryer housing and the cylinder head housing. The invention also relates to a compressor and an assembly method with the housing system.

Air dryer housings and cylinder head housings of a housing system of the type mentioned at the outset, in particular for mounting on a compressor for generating compressed air, are known.

An air dryer housing described at the outset and a cylinder head housing for mounting on a compressor are, for example, in DE 199 11 933 B4 described. A compressed air generator there has an air dryer housing containing a desiccant and a cylinder head housing. The cylinder head housing is part of an air compression device which is driven by a drive means. It is envisaged to attach the air dryer housing to the cylinder head housing by means of a releasable closure. For this purpose, a fastening section with a wedge-shaped groove is formed on the cylinder head housing, a projection of the air dryer, formed from the air dryer housing and a cover, hooking into the groove and thus connecting the two housings to one another.

In DE 100 51 471 A1 describes a detachable screw connection between an air dryer housing with a desiccant cartridge and a compressed air system.

Out EP 1 233 183 B1 a connection between an air dryer housing and a compressor is known, which is realized by means of a number of screws. Here, an air dryer housing filled with desiccant or the like is non-positively connected to a compressor housing by separate screws.

Concepts of this type are essentially either restricted to air dryer housings in a single-chamber construction, that is to say to air dryers with a lower air volume throughput, or require a comparatively high component and, as a result, assembly work. The connection concepts mentioned are still in need of improvement. In particular, connection concepts of this type between the housing parts can be improved to ensure a secure and stable connection.

It is therefore desirable to implement a simple, detachable connection between the air dryer housing and the cylinder head housing, in particular with relatively little, in particular construction and material, effort. Furthermore, it is desirable that the connection between the housing parts should be designed to be easily detachable, but at the same time ensures a secure and stable connection between the air dryer housing and the cylinder head housing.

This is where the invention comes in, the task of which is to provide an air dryer housing, a cylinder head housing and a housing system and a compressor which solve the problems addressed above. It is also an object to specify an assembly method in which the outlay on components, and therefore the assembly outlay for a connection of this type, is reduced. At least an alternative solution to the existing design of the air dryer and cylinder head housing and their connection in a housing system should be proposed.

The object relating to the air dryer housing is achieved by the invention with an air dryer housing according to claim 1.

The invention is based on an air dryer housing with a receptacle for an air drying cartridge or similar air drying agent, for mounting on a cylinder head housing of a compressor or similar compressor. The air dryer housing has an air dryer housing edge which has a first part of a first connecting means and a first part of a second connecting means. The first part of the second connecting means on the edge of the air dryer housing lies opposite the first part of the first connecting means. The air dryer housing edge spans a connection level between the air dryer housing and the cylinder head housing, the first and second connecting means being designed to implement a releasable connection on the air dryer housing edge.

According to the invention, it is provided in the air dryer housing that a holding connection can be formed for the releasable connection to the first connecting means. By means of this holding connection, the air dryer housing can be pivoted about an axis along the connection plane to the cylinder head housing. The second connecting means can be formed as a clamping connection, by means of which the air dryer housing can be clamped to the cylinder head housing against a holding force of the holding connection.

According to the invention, it is provided that the first part of the first connecting means is designed as a first holding part in the form of an axial insertion pin and / or an axial holding groove with an axial extension along the axis. The first part of the second connecting means is designed as a first clamping part in the form of a holding means.

The object relating to the cylinder head housing is achieved by the invention with a cylinder head housing according to claim 3.

The invention is based on a cylinder head housing of a compressor or similar compressor, preferably with a housing for a crank mechanism or similar compressor unit, in particular for attachment to a drive for the compressor unit. The cylinder head housing has a cylinder head housing edge, with a second part of a first connecting means and a second part of a second connecting means. The second part of the second connecting means lies opposite the second part of the first connecting means on the edge of the cylinder head housing. The cylinder head housing edge spans a connection plane between the air dryer housing and the cylinder head housing, the first and second connecting means being designed to implement a releasable connection on the cylinder head housing edge.

According to the invention, it is provided in the cylinder head housing that a holding connection can be formed for the releasable connection to the first connecting means. By means of this holding connection, the air dryer housing can be pivoted about an axis along the connection plane to the cylinder head housing. The second connecting means can be formed as a clamping connection, by means of which the air dryer housing can be clamped to the cylinder head housing against a holding force of the holding connection.

It is provided according to the invention that the second part of the first connecting means is designed as a second holding part in the form of an axial insertion pin and / or an axial holding groove with an axial extension along the axis. The second part of the second connecting means is also designed as a second clamping part in the form of a counter-holding means.

The invention achieves the object relating to the device, also to a housing system of claim 5, i. H. with an air dryer housing and cylinder head housing according to the concept of the invention, namely the air dryer housing according to claim 1 and the cylinder head housing according to claim 3.

According to the invention, it is provided in the housing system that the air dryer housing is positioned on one side relative to the cylinder head housing by the first connecting means, designed as a holding connection. In an insertion position, the axial insertion pin is inserted in the axial holding groove of the holding connection. As a result, the air dryer housing can be pivoted about an axis along the connection plane to the cylinder head housing. The holding means and the counter-holding means of the second connecting means implement the clamping connection, by means of which the air dryer housing can be clamped against the holding head of the holding connection to the cylinder head housing.

The invention achieves the object relating to the device, also to a compressor or compressor of claim 20.

According to the invention, the compressor or the like compressor has a compressor unit and a compressor drive for driving the compressor unit, at least one housing system for connection to the compressor or the like compressor, the housing system having the air dryer housing and the cylinder head housing according to the concept of the invention.

The invention achieves the object relating to the method for an assembly method of claim 21.

According to the invention, the assembly method has the steps: inserting an insertion pin into a holding groove, so that the air dryer housing and the cylinder head housing are connected on one side and have a variable opening angle on the opposite side; Pivoting the air dryer housing in the insertion position until the air dryer housing lies flat on the cylinder head housing; Fixation of the air dryer housing and the cylinder head housing on one side by the first clamping mechanism, in particular by the geometrical design of the insertion pin and the holding groove; Securing the connection between the air dryer housing and the cylinder head housing by means of the second clamping mechanism, formed from holding means and counter-holding means, in particular designed as a screw connection or clamping tooth / clamping groove connection or by means of the flange of the drive means; Screwing the housing system to the crankcase, in particular depending on the selected version of the second clamping mechanism.

The invention is based on the consideration that it is generally advantageous to keep the effort involved in installing an easily detachable air dryer housing, in particular the effort that results from the number of components required, as low as possible, but without the durability and reliability of the connection restrict negatively. Therefore, it is fundamentally advantageous to implement a detachable connection on the edge of the housing.

In addition, however, the invention has advantageously recognized to create an easily detachable, yet safe and stable connection.

The concept of the invention primarily provides that the first connection means can be formed according to the invention as a holding connection, by means of which the air dryer housing can be pivoted about an axis along the connection plane to the cylinder head housing. Accordingly, it is provided according to the invention that the first part of the first connecting means is designed as a first holding part in the form of an axial insertion pin and / or an axial holding groove with an axial extension along the axis. Accordingly, the second part of the first connecting means is designed according to the invention as a second holding part in the form of an axial insertion pin and / or an axial holding groove with an axial extent along the axis.

The air dryer housing can advantageously be pivoted in particularly easily about an axis along the connection plane to the cylinder head housing and can then be locked.

The concept of the invention primarily provides that the second connecting means can be formed according to the invention as a clamping connection, by means of which the air dryer housing can be clamped to the cylinder head housing against a holding force of the holding connection. Accordingly, it is provided according to the invention that the first part of the second connecting means is designed as a first clamping part in the form of a holding means. Furthermore, the second part of the second connecting means is designed according to the invention as a second clamping part in the form of a counter-holding means.

This creates a secure and stable connection for a housing system and the compressor. The same advantages are established analogously in the assembly process.

The invention is based on the finding that the first part of the first connecting means of the air dryer housing can be arranged along one of the outer edges of the air dryer housing edge. This results in the advantage according to the invention that the air dryer housing can be positioned as desired relative to the connection component without the function described being adversely affected. Furthermore, this design results in the advantage according to the invention of a largely arbitrary spatial arrangement of further components of the compressor or similar compressor. The overall assembly of the compressor can thus advantageously be improved, and partial disassembly of components, for example for maintenance purposes, can be facilitated.

The invention is based on the finding that the second part of the first connecting means of the cylinder head housing can be arranged along one of the outer edges of the edge of the cylinder head housing. It is thus made possible according to the invention to position the corresponding air dryer housing in a particularly advantageous manner relative to the cylinder head housing during its assembly. This results in the advantage according to the invention, a largely arbitrary spatial arrangement of further components of the compressor or the like compressor. The overall assembly of the compressor can thus advantageously be improved, and partial disassembly of components, for example for maintenance purposes, can be facilitated.

Advantageous developments of the invention can be found in the subclaims and specify in particular advantageous possibilities for realizing the above-explained concept of a housing system in the context of the task and with regard to further advantages.
The insertion pin, in combination with the housing having the holding groove, advantageously forms a releasable clamping mechanism, with a release and a clamping position being feasible. In particular, in a development of the housing system it is provided that the releasable clamping mechanism, which is formed by an advantageous combination of insertion pin and the housing having the retaining groove, has a first and a second clamping element. The first clamping element is formed by the housing itself on which the axial holding groove is formed. The second clamping element is formed by the axial ends of the axial insertion pin. The axial ends of the first and second clamping elements of the clamping mechanism are advantageously geometrically shaped. The geometric design of the respective axial ends of the insertion pin and of the housing having the retaining groove advantageously realize a technical function by means of which the clamping mechanism can be represented.

In general, it has proven to be advantageous that the second clamping element of the clamping mechanism has a flattened line circumferential section, along which the air dryer housing can be displaceably guided on the cylinder head housing. Additionally or alternatively, it is advantageous that the second clamping element of the clamping mechanism has a circular circumference, along which the air dryer housing on the cylinder head housing can be pivoted.

It is also advantageously provided that the air dryer housing can be fixed on one side to the cylinder head housing by the holding connection, formed by the first connecting means.

If the air dryer housing and cylinder head housing are in the insertion position, that is, if the insertion pin lies in the holding groove, the clamping mechanism can be implemented. In particular, it is provided that, depending on a variable opening angle between the air dryer housing and the cylinder head housing, the clamping mechanism can transition from a release position into a clamping position. It is advantageously provided here that the clamping element of the air dryer housing can engage with the clamping element of the cylinder head housing. As soon as the air dryer housing lies flush on the cylinder head housing, the clamping elements of the clamping mechanism can fully engage with one another. In particular, this means that the air dryer housing and the cylinder head housing are already securely fixed to one another on one side, without additional material or assembly effort being necessary, as would be the case, for example, when using a complete screw connection.

In the context of a preferred development, it is provided in particular that the first clamping element of the clamping mechanism is geometrically shaped as a circular segment-shaped groove on the housing, which has the axial holding groove, the circular segment-shaped groove being formed on the opposite axial ends of the axial holding groove. Said housing has at least one, but advantageously two such circular segment-shaped grooves. It is further provided that the second clamping element of the clamping mechanism is formed by the axial ends of the axial insertion pin, the respective end at least on one side transverse to the axis in the axial extent of the axial insertion pin, flattened, preferably flat, surface with limited extent in the axial direction of the Has insertion pins.

It is advantageously provided that the radius of the first and the second clamping element of the clamping mechanism is the same. In particular, the radius of a circular segment-shaped groove on the housing is equal to the radius on a head extension on the axial insertion pin.

The description of the circular segment-shaped groove on the housing having the holding groove means, in particular, a circular segment-shaped depression on either the air dryer housing or the cylinder head housing depending on the specific design of the housing system in the individual case. The groove in the shape of a segment of a circle at the opposite ends of the holding groove is of limited axial extent and has a radius which is identical to that of the corresponding insertion pin. In particular, the radius of the insertion pin can deviate from this radius in an area that does not belong to the first clamping mechanism.

Furthermore, the description of the flattened, preferably planar, surface at the respective axial ends of the insertion pin means in particular the flattening on one side of an otherwise cylindrical insertion pin with limited axial expansion, in particular with an axial expansion corresponding to the circular segment-shaped groove. The insertion pin advantageously has a transverse to the axis at both ends A in the axial extent E flattened, preferably flat, surface, which - in the insertion position - is coplanar with the connection side or connection plane of either the cylinder head housing or the air dryer housing.

This geometric design of the respective ends results in the advantage that the housing on which the insertion pin is formed can be inserted into the holding groove of the respective other housing of the housing system. This is possible on the condition that the plane of the surface of the insertion pin, preferably plan, transverse to the axis in the axial extent is coplanar with the plane which is formed by the connection side or connection plane of the corresponding housing. This level is called the connection level. In this case, the insertion pin can then be inserted into the holding groove and the air dryer housing has a variable opening angle relative to the cylinder head housing. If one of the two housings is now pivoted in the insertion position so that both housings lie flat on one another, the preferably flat surface of the insertion pin is also rotated into the circular segment-shaped groove of the holding groove. The air dryer housing is then clamped on one side with the cylinder head housing and thus secured on one side against unintentional misalignment.

If the connection between the air dryer housing and the cylinder head housing is intended to be released again, one of the two housings can be pivoted back into the starting position, so that the insertion pin is no longer in engagement with the circular segment-shaped groove of the holding groove. This applies on the condition that the second connection means is not yet in place.

The second clamping element of the clamping mechanism is preferably formed with a head extension on the axial insertion pin, which extends essentially transversely to the axis in the axial extent. In particular, the head extension on one side of the axial insertion pin has a flattened, preferably flat, surface which extends transversely to the axis in the axial extent. The preferably flat surface which is flattened transverse to the axis in the axial extent preferably delimits the surface Head extension on the front. In particular, the flattened surface is bordered by a circumferential course to form a frame of the head extension.

In the context of a particularly preferred further development, the clamping mechanism is advantageously formed by the design of the head extension.

It is advantageously provided that the head extension on the axial insertion pin has a circumferential course. In particular, the circumferential course is the same as that of a face, preferably a planar surface, on the head extension. The circumferential course advantageously has a circular circumference, in particular a circular section.

It is advantageously provided that the head extension on the axial insertion pin has a circumferential course with a number of line circumferential sections, in particular secants. Provided with particular advantage is the number of line circumferential sections, in particular secants, on the circumferential course relative to the circular circumference rounding, in particular the circular section. The circular circumference rounding preferably takes an angle of more than 180 ° on the circumferential course and / or the number of line circumferential sections forms an angle of less than 180 ° on the circumferential course.

As part of the further development, the clamping mechanism is advantageously established in that the number of line circumferential sections of a circumferential course - in particular the line circumferential sections of a circumferential course on a border of the front, preferably planar, surface of the head extension - on the head extension for free insertion in a, preferably circular segment-shaped groove are formed at one end of an axial holding groove. In particular, it is provided that a circular circumference is designed to engage the groove, which is preferably in the form of a segment of a circle, for clamping action, in particular at the respective opposite axial ends of the axial holding groove.

On a circumferential course of the second clamping element, preferably on the head extension, at least one of the number of line circumferential sections is advantageously provided for guiding on a leading edge of the first clamping element; in particular in the case of a line circumferential section and guide edge which are aligned in parallel, ie if the housing opening planes are aligned opposite one another with an opening angle - this is illustrated by a non-limiting example of a preferred embodiment in 7 (i) shown.

Advantageously, at least the part of the circular circumference that immediately adjoins the line circumference section for latching under the leading edge is advantageously formed on the head extension — this is explained using a non-limiting example of a preferred embodiment 7 (ii) shown.

In a preferred development, it is provided that the second connecting means, which is designed as a holding and counter-holding means of a clamp connection, primarily secures the air dryer housing against a rotational movement about an axis which is collinear with the axis of the insertion pin as soon as the air dryer housing and the cylinder head housing is in the insertion position. Thus, according to a development of the invention, a particularly advantageous connection between the air dryer housing and the cylinder head housing can be achieved with minimal effort in terms of assembly and additionally required material. The overall assembly of the compressor can also be advantageously improved in this way, and partial disassembly of components, for example for maintenance purposes, can be facilitated.

In particular, it is further provided that the second connecting means, which realizes a clamping connection between the air dryer housing and the cylinder head housing, is designed as a non-positive screw connection. It is provided according to the invention that the first part of the second connecting means is designed as a threaded hole and the second part of the second connecting means is designed as a through hole or the like. In this embodiment, an additional connecting screw is also required, which is guided through the through hole and screwed into the corresponding thread. As a result, the air dryer housing is thus completely fixed to the cylinder head housing. This first suggestion of a specific embodiment of the second connecting means has the advantage that, compared to the known prior art for air dryer housings in a multi-chamber construction, at least the material expenditure and, consequently, the assembly expenditure are reduced.

As part of a preferred development, in particular as an alternative to the previously mentioned variant, the second connecting means is provided such that the second connecting means is designed as a form-fitting, two-part clamp connection. It is provided here that a first part of the clamping connection is formed by a number of clamping teeth which are formed on the crank mechanism or the like compression mechanism. In this embodiment variant, it is further provided that a number of corresponding clamping grooves are formed on the air dryer housing for the clamping teeth. The housing system, consisting of air dryer housing and Cylinder head housing, is then connected on one side by means of insertion pin and retaining groove and then screwed onto the crank mechanism or similar compression mechanism. The clamping teeth thus come into contact with the clamping grooves on the air dryer housing. As a result, the air dryer housing is secured against rotation on the cylinder head housing and thus completely fixed. This embodiment variant realizes a particularly advantageous connection between the air dryer housing and the cylinder head housing, since additional components such as screws or the like can be completely dispensed with.

In particular, as a further alternative to the aforementioned embodiment variants with regard to the second connecting means, it is provided that the aforementioned second connecting means is likewise designed here as a form-fitting, two-part clamping connection, but deviating from the previous variant, the cylinder head housing and the crank mechanism or similar compression mechanism are provided as integral parts Execute monoblock. The clamp connection of the second connecting means is then formed by a preferably flat, segment-shaped surface on the air dryer housing and by the flange of the drive means of the compressor or the like compressor. For this purpose, it is provided that the flange of the drive means lies flat on the corresponding, circular segment-shaped surface of the air dryer housing in the assembly position. As soon as the drive means is screwed to the monoblock, the air dryer housing is clamped between the flange and the monoblock and thus secured against rotation. The air dryer housing is thus fixed to the monoblock. Alternatively, this embodiment variant realizes a particularly advantageous connection between the air dryer housing and the monoblock, consisting of the cylinder head housing and the crankcase. In this embodiment variant, additional components such as screws or the like can also be completely dispensed with.

It is provided in the present case that the clamping mechanism 500 from one in 3C shown release position 530A in an in 3D shown clamping position 530B can pass over.

3A shows in front of a release position 530A so the cylinder head housing 200 and the air dryer housing 100 in a released position to each other before assembling and 3B shows the cylinder head housing 200 and the air dryer housing 100 in an assembled position after or in the clamping position 530B .

The clamping mechanism 500 is in a to the released position in 3A matching release position 530A shown specifically in 3C and the corresponding clamping position 530B is again shown in concrete terms in 3D (suitable for the composite position of the 3B) . The following is the 3C and 3D taken together for further explanation of the connection means 110 for the holding connection 700 like it in 3A and 3B is designated.

The clamping mechanism 500 is formed by the geometric design of the insertion pin 130 on the one hand and the holding groove 140 having housing on the other hand. The insertion pen 130 points at its opposite axial ends to a cross to the axis A in the axial extent E flattened, preferably flat surface 510 , which faces the subsequent housing. The housing on which the retaining groove 140 is pronounced, points in the region of the opposite axial ends of the retaining groove 140 a circular segment-shaped groove N on.

The axial extent of both clamping elements 520A , 520B is the same here. The radius R2 the insertion pin 130 and the radius R1 the groove N at the holding groove 140 on the housing 200 are in the area of this clamping mechanism 500 equal and larger than that in 3A designated radius R in the area of the holding groove 140 . In the area of the holding groove 140 In this respect, the radii correspond R the insertion pin 130 and the holding groove 140 .

The insertion pin 130 with the holding groove 140 engaged ( 2nd , B → A), the air dryer housing is located 100 first in the in 3C shown release position 530A , provided that a leading edge F1 of the cylinder head housing 200 facing, on the line peripheral portion U1 flattened side formed (then partially K1 the circumference rounding K ) on the head extension 131 the insertion pin 130 is coplanar with a connection level 190A of the cylinder head housing 200 . There is between the air dryer housing 100 and cylinder head housing 200 a variable opening angle Ö ( 2nd ), based on the concrete opening angle Ö1 , Ö2 in 7 is explained in more detail. When closing the opening angle Ö does this as in 3D shown, then in the state of 3B the connection levels 190A , 190B , 190B on the housings 100 , 200 together and thus closes the air dryer housing 100 to the cylinder head housing 200 at.

This situation is shown in the transition of the positions of the housing system 900 from the opening angle Ö1 in 3C to the opening angle Ö2 in 3D respectively. 7 (i) on 7 (ii) .

If the position of the 3C , 7 (i) occupied first opening angle Ö1 reduced to the second opening angle Ö2 in the position of the 3D , 7 (ii) so the air dryer housing 100 So in the direction of the cylinder head housing 200 pivoted about the axis A , which is collinear with the axis of the insertion pin 130 . Finally both clamping elements arrive 520A , 520B of the clamping mechanism 500 engaged. This situation is specifically shown in 7 (iii) which the in 3D , 7 (ii) recognizable second opening angle Ö2 reduced to zero.

As soon as both clamping elements 520A , 520B of the clamping mechanism 500 for the holding connection 700 completely engaged, like that in 7 (iii) recognizable is the air dryer housing 100 held on one side relative to the cylinder head housing 200 . This connection can be released in reverse order.

Is in 3C and 3D can be seen that the second clamping element 520B of the clamping mechanism 500 with a head extension 131 on the axial insertion pin 130 is formed. The head extension 131 extends essentially transverse to the axis A (the axis in the in 5 shown axial extension E ) and has a flattened, preferably flat, surface on the end face 510 on. The flattened area 510 is with one in the 3C shown side, on the face of the axial insertion pin 130 formed and extends across the axis A in the axial extent E . Analog is also present here in 3C not visible flattened surface, on the opposite end of the in the 3C shown side - so on the opposite side - on a further head extension on the axial insertion pin 130 formed and also extends transversely to the axis A in the axial extent E . The head extension is present 131 on the axial insertion pin 130 further explained and the explanation applies to that in 3C visible head extension 131 as well as the head extension opposite the front, which in 3C is not visible.

The head extension 131 the axial insertion pin has a circumferential profile already mentioned above U on that in a kind of frame Z in the axial direction of the head extension 131 transforms. The circumferential course U has a circular circumference here K , namely here in the form of a segment of a circle. This circular circumference K borders the previously mentioned preferably flat surface 510 on the insertion pin 130 and is located on the face of the head extension 131 ; the circumference rounding K is a number of line circumference sections U1 , U2 , U3 on the circumferential course opposite; the latter line peripheral portions U1 , U2 , U3 are executed here as secants. The line perimeter sections U1 , U2 , U3 limit the previously flattened area 510 in the sense of a border on the head extension 131 on the insertion pin 130 , in other words on the head extension 131 . The circular circumference K takes an angle of more than 180 ° on the circumferential course U of the flattened area 510 one and the number of line circumferential sections U1 , U2 , U3 together make an angle of less than 180 ° on the circumferential course U of the flattened area 510 a.

On the head extension 131 is now with this formation of the number of line peripheral sections U1 , U2 , U3 , as in 3C initially recognizable, for free insertion into the circular segment-shaped groove N at the opposite axial ends of the axial retaining groove 140 educated. As in 3D recognizable then serves - when reducing the first opening angle Ö1 to the second opening angle Ö2 in the position of the 3D , 7 (ii) - the circumference rounding K intervention in the circular segment-shaped groove for a clamping effect N at the opposite axial ends of the axial retaining groove 140 .

Concretely serves on the head extension 131 initially at least one peripheral section U1 the number of line perimeter sections U1 , U2 , U3 for guiding on a leading edge F1 . The part immediately following it K1 the circumference rounding K then clicks in; he clicks under the leading edge F1 when reducing the first opening angle Ö1 to the second opening angle Ö2 in the position of the 3D , 7 (ii) . The clamping mechanism comes about in that the line peripheral portion U1 of the second clamping element 520B for guiding at the leading edge F1 of the first clamping element 520A a beveled surface, so to speak, to the part immediately adjacent to it K1 a circular circumference K on the frame Z the head extension 131 forms.

In this embodiment, it is shown by way of example how the second clamping element is advantageous, but nevertheless generally 520B of the clamping mechanism 500 with a flattened line peripheral portion U1 can be provided along which the air dryer housing 100 on the cylinder head housing 200 can be moved. For example, like here a flattened circular section around the air dryer housing 100 from above into the holding groove 140 to be able to introduce. It has been used for the second clamping element 520B of the clamping mechanism 500 also generally a circular circumference K proven advantageous along the air dryer housing 100 on the cylinder head housing 200 can be pivoted, namely for engaging in the circular segment-shaped groove N on the cylinder head housing 200 .
4th shows in concrete terms essentially a preferred alternative development of the second connecting means 120 that the clamp connection 600 between air dryer housing 100 and cylinder head housing 200 realized. There is a first and a second part of the first connecting means 110 on one of the for example in 2nd opposite side shown to the second connecting means 120 .

The clamp connection of the second connecting means 120 is used here in a second variant of a clamp connection 602 preferably formed by a number of clamping teeth 610A and corresponding clamping grooves 610B .

According to 4th it is provided in this embodiment that the housing for a crank mechanism 300 of the compressor or the like compressor 1000 a number of clamping teeth 610A has, the air dryer housing 100 again corresponding clamping grooves 610B having. It is provided in this development that the air dryer housing 100 in a first step with the cylinder head housing 200 one-sided by means of the holding connection described above 700 is connected. The next step is the housing system 400 with the housing for a crank mechanism 300 screwed, the clamping teeth 610A on the housing for a crank mechanism in the corresponding clamping grooves 610B of the air dryer housing 100 intervention. The air dryer housing 100 is therefore completely on the cylinder head housing 200 fixed. Advantageously, in this embodiment variant, no additional screws or the like are required for the air dryer housing 100 with the cylinder head housing 200 to a housing system 400 connect to. This means that this embodiment variant is particularly advantageous with regard to the material and assembly effort required.

5 shows specifically the closed preferred alternative development of the second connecting means 120 in a different view. The clamp connection 600 is the third variant of a clamp connection 603 between Air dryer housing 100 and cylinder head housing 200 realized. The first connection means is located here 110 on one of the for example in 2nd opposite side shown to the second connecting means 120 . In this embodiment variant, it is provided that the cylinder head housing 200 and the housing for a crank mechanism 300 , integral as a monoblock 710 are executed. The third variant of a clamp connection 603 is formed here by a flat, segmented surface 720A , formed on the air dryer housing 100 as well as through a flange 720B a driving means of the compressor or the like compressor. It is provided here that the air dryer housing during assembly of the compressor 100 in a first step with the integral monoblock 710 one-sided by means of the holding connection described above 700 is connected. In a next step it is then provided that the drive means of the compressor 1000 via a flange connection 720B also with the compressor 1000 is connected. The flange of the drive means lies flat on the surface provided 720A of the air dryer housing 100 on. The air dryer housing 100 is therefore between monoblock 710 and flange 720B clamped fixed. The air dryer housing 100 is therefore completely on the monoblock 710 fixed. Advantageously, in this embodiment variant, no additional screws or the like are required for the air dryer housing 100 with the monoblock 710 connect to. This means that this embodiment variant is particularly advantageous with regard to the material and assembly effort required.

According to the 6A , 6B and 6C is essentially labeled with the 1A and 1 B an assembly process 800 shown schematically, in which the clamp connection 600 as a screw connection of a first variant of a clamp connection 601 is executed.

The assembly procedure described 800 applies - taking into account the necessary modifications - but also for the alternative design variants of the clamp connection 602 , 603 . Once the air dryer housing 100 and the cylinder head housing 200 in the loading position B are located - such as in 2nd schematically shown -, is the air dryer housing 100 around an axis A to pivot in a swivel motion S , with the axis A is collinear with the axis of the insertion pin 130 . This will make the opening angle Ö between air dryer housing 100 and cylinder head housing 200 reduced until the air dryer housing 100 flat on the cylinder head housing 200 lies on.

These assembly steps 810 , 820 are shown schematically in the 6A and 6B . In a subsequent assembly step 830 , the air dryer housing 100 one-sided to the cylinder head housing 200 held by the clamping mechanism 500 , formed by the clamping elements 520A , 520B . In a final assembly step 840 , is a single screw 900 through the through hole 160 to guide and into the threaded hole 150 screw in. This assembly step 840 is shown schematically in the 6C . The air dryer housing 100 is thus completely on the cylinder head housing 200 fixed. The last step is according to the variant 602 , 603 the clamp connection 600 adapt.

In relation to 7 is for a first step in view (i) the relative arrangement of the air dryer housing 100 and cylinder head housing 200 with an opening angle Ö1 , like using 3C explained, shown; latter 3C is with the release position 530A here in detail X1 shown. The geometric design of the respective ends as a head extension 131 the axial insertion pin 130 is such that the air dryer housing 100 on which the insertion pin 130 is trained in the holding groove 140 of the cylinder head housing 200 of the housing system 400 can be inserted.

This is possible on the condition that the plane of the plane surface of the insertion pin 130 - That is, the area which is through the line circumferential section U1 is bordered - is coplanar with the connection level 190A , which is formed by the connection side of the corresponding cylinder head housing 200 - That is the plane which is the leading edge F1 having--. This level is the first connection level 190A designated. In this case, the insertion pin can then be used 130 in the holding groove 140 insert and the air dryer housing 100 has a variable opening angle Ö1 relative to the cylinder head housing 200 on.

In 7 can now be seen in view (ii) and (iii) for a second and third step that by reducing the opening angle Ö1 to Ö2 (View (ii)) of one of the two housings 100 , 200 is pivoted; ie roughly with the in 6A designated pivoting movement S .

In the present case the air dryer housing 100 swiveled in the insertion position so that the cylinder head housing 200 and the air dryer housing 100 in the area of the first and second connection level 190A and 190B Lie flat on top of each other (view (iii) - angle ZERO).

In this state, this leads to the first connection level 190A on the cylinder head housing 200 and the second connection level 190B on the air dryer housing 100 together and thus closes the air dryer housing 100 to the cylinder head housing 200 at.

In this case, the preferably flat surface of the line peripheral section is also U1 on the head extension 131 on the insertion pin 130 in the circular segment-shaped groove N the holding groove 140 rotated into it, like this based on 3D was explained and the in 7 (ii) in detail X2 with reference to the first and second clamping element 520A , 520B of the clamping mechanism 500 is shown. So then the air dryer housing 100 on one side with the cylinder head housing 200 jammed and thus one-sided against unintentional misalignment in the first and second connection levels 190A , 190B secured.

If you intend to disconnect the air dryer housing and cylinder head housing again, one of the two housings can 100 , 200 back to the starting position of the 7 (i) be pivoted back. In the case, the air dryer case 200 can be removed upwards and there is the insertion pin 130 then no longer in engagement with the circular segment-shaped groove N the holding groove 140 . This applies provided that the second connection means, here the in 7 (iv) connecting screw shown 900 , does not yet apply.

As part of a preferred development, it is also provided that the second connecting means - here the in 7 (iv) connecting screw shown 900 - Which is designed as a holding and counter-holding means of a clamp connection 600 in the first variant of a clamp connection 601 , the air dryer housing primarily secures against swiveling movement around an axis A which is collinear with the axis of the insertion pin 130 as soon as the air dryer housing 100 and the cylinder head housing 200 are in the loading position.

This allows a particularly advantageous connection of the air dryer housing 100 and cylinder head housing 200 can be achieved with minimal effort in terms of assembly and additional material required. The overall assembly of the compressor can also be advantageously improved in this way, and partial disassembly of components, for example for maintenance purposes, can be facilitated.

In particular, it is further provided that the second connecting means - here the in 7 (iv) connecting screw shown 900 - That realizes a clamp connection between the air dryer housing and the cylinder head housing, is designed as a non-positive screw connection. It is provided here that the first part of the second connecting means is designed as a threaded hole and the second part of the second connecting means as a through hole 901 or the like is executed. In this embodiment, an additional connecting screw is also used 900 needed through the through hole 901 out and into the corresponding thread of the cylinder head housing 200 is screwed in. The result is the air dryer housing 100 thus completely on the cylinder head housing 200 fixed. This first proposal of a concrete design of the second connecting means as a screw 900 has the advantage that, compared to the known state of the art for air dryer housings in a multi-chamber construction, at least the material expenditure and, consequently, the assembly expenditure is reduced.

In relation to 8th In the context of a second embodiment, as an alternative to the previously mentioned variant, the second connection means is provided that the second connection means is a positive, two-part clamp connection 602 is executed.

It is provided here that a first part of the clamping connection is formed by a number of clamping teeth 610A which on the crank mechanism 300 or similar compressor work are formed. In this embodiment variant it is further provided that the clamping teeth 610A a number of corresponding clamping grooves 610B on the air dryer housing 100 are trained on how to do this using 4th is explained.

The housing system 400 consisting of air dryer housing 100 and cylinder head housing 200 , is first unilaterally using an insertion pin 130 and holding groove 140 connected as shown in view (i) of the 8th is shown.

The clamping teeth arrive 610A in contact with the clamping grooves 610B on the air dryer housing 100 if - similar or analogous to the assembly as it is based on 7 was explained - a variable opening angle Ö while swiveling the air dryer housing 100 to the cylinder head housing 200 or vice versa, as shown in view (i) of 8th is shown - the opening angle Ö is while swiveling the air dryer housing 110 towards the cylinder head housing 200 reduced to zero like this in view (ii) of the 8th is shown. In this state, this in turn leads to the first connection level 190A on the cylinder head housing 200 and the second connection level 190B on the air dryer housing 100 together and thus closes the air dryer housing 100 to the cylinder head housing 200 at.

Then the housing system 400 on the crank mechanism 300 or similar compressor work with corresponding screw connections 301 screwed - this is in view (iii) and (iv) of the 8th shown. The result is the air dryer housing 100 on the cylinder head housing 200 secured against rotation and thus completely fixed.

This embodiment variant realizes a particularly advantageous connection between the air dryer housing and the cylinder head housing, since this involves additional components such as screws 900 or the like can be completely dispensed with.

It is particularly another alternative to the 5 In relation to the above-mentioned embodiment variants with regard to the second connecting means, the previously mentioned second connecting means is also provided here as a positive, two-part clamp connection 602 , 603 is executed, but deviating from the previous variant, the cylinder head housing is provided 200 and the crank mechanism 300 or the like compressor unit as an integral monoblock.

The clamp connection 600 as the third variant of a clamp connection 603 of the second connection means is then, as already based on 5 explained formed by a flat, segmented clamping surface 720A on the air dryer housing 100 as well as through a flange 720B the drive means of the compressor, not shown here 1000 or the like compressor. For this purpose it is provided that the flange 720B of the drive means not shown here in the mounting position flat on the corresponding, circular segment-shaped surface 720A of the air dryer housing 100 lies on.

As soon as the one not shown here, on the flange 720B continuing drive means with the monoblock 710 is screwed, the air dryer housing 100 clamped between the flange 20B and monoblock 710 and thus secured. The air dryer housing 100 is on the monoblock 710 from cylinder head housing 200 and crankcase 300 fixed. Alternatively, this embodiment variant realizes a particularly advantageous connection of the air dryer housing 100 and monoblock 710 consisting of cylinder head housing 200 and crankcase 300 . In this embodiment variant, additional components such as screws or the like can also be completely dispensed with.
