Description

Technical Field

[0001] The invention relates to a valve cartridge. Background Art

[0002] Valve cartridges are known, for example, in single-lever mixing valves or in push-push valves with or without additional temperature and / or flow control.

[0003] The valve cartridge has a housing which holds the individual components together even in the disassembled state.

[0004] The valve cartridge is usually inserted into a corresponding cup-shaped receptacle which has a hose receptacle or a hose connection in each case in order to produce the fluid connection. Summary of the invention

[0005] The invention is based on the object of simplifying the design of the valve cartridge.

[0006] To achieve this object, the invention provides the features of claim 1. In particular, the valve cartridge is characterized in that at least one plug-in receptacle is formed in the connection-side housing part. This makes it possible, for example, to connect a hose to the valve cartridge. The invention makes it possible to dispense with a separate cartridge receptacle on which a hose connection is formed or to which a hose is fastened.

[0007] In an advantageous embodiment, it is provided that the plug receptacle is designed for a preferably axially oriented plug connection of a connecting hose. This makes it possible, for example, to plug a connecting hose into the plug receptacle.

[0008] In an advantageous embodiment, it is provided that the housing parts are connected by means of a loss prevention device. This makes it possible, for example, for the housing part on the operating element side to be connected to the housing part on the connection side in a loss-proof manner. This can be achieved, for example, via a snap-on or latching connection.

[0009] In an advantageous embodiment, it is provided that at least two plug-in receptacles are provided. This makes it possible, for example, to fasten two connecting hoses to the valve cartridge. In particular, it can be provided that at least three plug-in receptacles are provided. This makes it possible, for example, to fasten three connecting hoses to the valve cartridge. The plug-in receptacles are designed in particular for a hot water hose, a cold water hose and a mixed water hose. The valve cartridge thus makes it possible for hot water and cold water to be mixed and for the mixed water to be drained away via the mixed water hose.

[0010] In an advantageous embodiment, it is provided that at least one plug-in receptacle has a pull-out prevention device, which can for example ensure that a connecting hose plugged into the plug-in receptacle cannot be pulled out or cannot be released by itself.

[0011] In an advantageous embodiment, it is provided that the at least one plug receptacle projects beyond the contact surface of the housing part on the connection side. This makes it possible, for example, for the plug receptacle to be formed outside the housing part on the operating element side. In particular, it can be provided that the at least one plug receptacle projects from the contact surface forming the housing bottom. This makes it possible, for example, for a connecting hose to be easily plugged into the plug receptacle. In particular, it is provided that the at least one plug receptacle projects tubularly from the contact surface forming the housing bottom. This makes it possible, for example, for a tubular connecting hose that is circular in cross section to be fixed in the plug receptacle.

[0012] In an advantageous embodiment, it is provided that the housing part on the operating element side forms at least one through-opening for the operating element, thereby making it possible, for example, to actuate a valve cartridge.

[0013] In an advantageous embodiment, it is provided that at least two disks for fluid control that can be moved toward one another are arranged in the interior, in particular in contact with one another. This allows, for example, the mixing ratio of hot and cold water and the water pressure in the valve cartridge to be adjusted. In particular, it can be provided that the at least two disks that can be moved toward one another in the interior are made of ceramic. This minimizes, for example, the deposits of scale on the ceramic disks.

[0014] In an advantageous embodiment, it is provided that at least one connecting hose is locked in the plug-in receptacle by means of a spring clip. This makes it possible, for example, to provide a pull-out prevention device for the connecting hose. In particular, the cold water hose and / or the hot water hose is locked in the plug-in receptacle by means of a spring clip. These water hoses are usually subject to high pressures of 2 to 8 bar. The locking of the spring clip, which engages in the groove of the hose connector, holds the hose in the plug-in receptacle very securely.

[0015] In an advantageous embodiment, it is provided that at least one connecting hose is locked in the plug receptacle by means of a claw. Thus, for example, a pull-out prevention device can be provided for the connecting hose by arranging the claw in the plug receptacle such that the claw resists pulling forces in the direction opposite to the plugging direction and prevents the hose from being pulled out. In particular, it is provided that at least the mixed water hose is locked in the plug receptacle by means of the claw. Thus, for example, an advantageous locking can be achieved for the mixed water hose, which is usually at a lower pressure than the cold water hose and the hot water hose.

[0016] In an advantageous embodiment, it is provided that the connecting hose comprises a hose nipple having a groove. A locking element, for example a spring clip, can engage in the groove to prevent pulling out and thus lock the connecting hose.

[0017] In an advantageous embodiment, it is provided that at least one connecting hose is locked in the plug receptacle by means of a claw and a spring clip. Thus, for example, it can be achieved that the connecting hose is particularly advantageously locked in the plug receptacle by means of a combination of two locking elements.

[0018] In this case or generally, it can be provided that at least one connecting hose is rotatable relative to the plug-in receptacle. This can, for example, reduce torsional stresses in the connecting hose. The rotatability can be achieved, for example, by the claw sliding on the connecting hose and / or by the rotatability of a claw carrier on which the claw is formed in a restraining device, which restrains the claw carrier. The restraining device can, for example, be designed so that the claw carrier presses the claw into the connecting hose in the event of a pull-out load. The restraining device and the claw carrier can cooperate in a manner known per se, so that the connecting hose can be pulled out of the claw carrier while the claw carrier is held against the pull-out direction. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The invention will now be described in more detail with the aid of an exemplary embodiment, but the invention is not limited to this exemplary embodiment. Further exemplary embodiments result from the combination of the features of individual or multiple claims with one another and / or with individual or multiple features of the exemplary embodiment.

[0027] The valve cartridge 1 has an actuating element-side housing part 2 which is captively connected to a connection-side housing part 3 .

[0028] At least one plug receptacle 4 for a connecting hose 5 is formed in the connection-side housing part 3. The plug receptacle 4 and the housing part 3 are therefore connected in one piece and are formed as a common injection-molded part.

[0029] The plug receptacle 4 is designed for a preferably axially oriented plug connection to a connecting hose 5. In this example, the connecting hose 5 is inserted, in other examples it is pushed on.

[0030] The housing parts 2 , 3 are connected via an anti-lost device 7 , such as a snap connection.

[0031] In this example, at least two, in particular at least three, plug receptacles 4 are provided, in particular for a hot water hose 13 , a cold water hose 14 and a mixed water hose 15 .

[0032] Each plug receptacle 4 has a pull-out protection 6 .

[0033] The plug receptacles 4 are each designed for a non-detachable plug connection, in particular via a pull-out protection 6 . The pull-out protection can have, for example, a locking element which engages in a groove 16 of the hose nipple 17 or which engages in a gripping manner with the connecting hose 5 .

[0034] Each plug-in receptacle 4 protrudes from a contact surface 8 of the connection-side housing part 3. In this case, the contact surface 8 can be used to clamp the valve cartridge 1 in a holder (not shown, for example on a sanitary fitting). In this case, the valve cartridge 1 is clamped on the housing part 2 between the contact surface 8 and the counter surface 19 (shoulder).

[0035] Each plug receptacle 4 therefore projects preferably in a tubular manner from a contact surface 8 which forms the housing bottom.

[0036] The housing part 2 on the operating element side forms at least one passage 9 for an operating element 10 .

[0037] At least two disks 12 for fluid control, preferably made of ceramic and movable toward one another (covered by the housing part 2 ), are arranged in the interior 11 (inside the pot-shaped housing part 2 ), in particular in contact with one another.

[0038] These disks can bear directly or indirectly against sealing elements on the housing part 3 , which are seated in the groove 18 .

[0039] Valve cylinder 1 Figure 4The embodiment shown in FIG. 4 shows a housing part 3 on the connection side, which has a connecting hose 4 inserted into a plug-in receptacle 4. The connecting hose 4 has a hose connector 17 with a groove 16, into which a spring clip 21 engages and locks the connecting hose 4. In this case, the spring clip 21 serves as a locking element. The housing part 3 on the connection side and the plug-in receptacle 4 have a receptacle 20 for the spring clip 21, so that the spring clip can be used to lock the connecting hose 4 there. The receptacle 20 is formed in the plug-in receptacle 4 of the hot water hose 13 and the cold water hose 14. In the embodiment shown, the cold water hose 14 and the hot water hose 13 are locked in the plug-in receptacle 4 by the spring clip 21.

[0040] The spring clip 21 is hereby guided externally around the plug receptacle 4 of the mixed water hose 15 and forms an arc 22 .

[0041] The arc 22 extends around the center 23 of the plug receptacle 4 of the mixed water hose 15 from the spring clip insertion direction so that the arc 22 engages the mixed water hose 15 from behind and narrows behind the mixed water hose 15. This forms a narrowing.

[0042] The spring clip 21 fixes the connecting hose 5 in the connection-side housing part 3 via the receptacle 20 .

[0043] The plug-in receptacle 4 of the mixed water hose 15 is located at Figure 4 An additional latch portion 24 is constructed in the middle. Figure 5 and Figure 6 The embodiment shown is without the latch 24 .

[0044] Figure 6 A further embodiment of the valve cartridge 1 is shown, in which the receptacle 20 also extends over the plug receptacle 4 of the mixed water hose 15 .

[0045] The spring clip 21 thus grips the mixed water hose 15 and thereby creates a retaining force on the mixed water hose 15 , which fixes the spring clip 21 in its insertion direction.

[0046] In an embodiment not shown, at least one connecting hose 15, in particular a mixed water hose 15, is locked in the plug receptacle 4 by means of a claw. In another embodiment not shown, at least one connecting hose is locked in the plug receptacle 4 by means of a claw and a spring clip 21.

[0047] The valve cartridge 1 having the operating element-side housing part 2 which is captively connected to the connection-side housing part 3 is characterized in that at least one plug receptacle is formed in the connection-side housing part 3 .
