Description

The invention relates to a cartridge adapter with a base body having at least one hose connection and an adapter part detachably connected thereto, wherein the adapter part has a cartridge side and a base body side, wherein the base body side has a contact area for contact with the base body. The invention further relates to a cartridge adapter with a base body having at least one hose connection and an adapter part detachably connected thereto, wherein the adapter part has a cartridge side and a base body side, wherein the base body side has a contact area for contact with the base body, wherein the cartridge side and the base body side preferably have connection openings connected fluidically to each other in pairs. The invention also relates to a set of different adapter parts that can be detachably connected to a common base body of a cartridge adapter and have a cartridge side and a base body side with connection openings. The invention further relates to a series of cartridge adapters, wherein at least two variants have a matching base body and different adapter parts. The invention further relates to the use of an adapter part, wherein the adapter part is detachably connectable to a base body to form a claimed cartridge adapter. is. The invention relates to a sanitary fitting with a claimed cartridge adapter. Cartridge adapters, especially one-piece cartridge adapters, are known from practical use and serve to connect a valve cartridge fluidically to hoses. For this purpose, the known hose connectors have a contact surface against which the valve cartridge can fit tightly, with connection openings corresponding to the inlets and outlets of the valve cartridge being formed in the contact surface, each of which is fluidically connected to a hose connector. Valve cartridges often provide a mixing function for blending hot and cold water and a flow control function for adjusting the flow rate. The corresponding cartridge adapters therefore have three hose connections, for example, for pressurized hot and cold water hoses and a mixed water hose designed for low pressure. Such valve cartridges can be designed, for example, as single-lever mixing cartridges or as rotary push-button valves. The invention is based on the objective of improving the interchangeability and/or variability of at least one component of the cartridge adapter by making the cartridge adapter multi-part. To solve the problem, the features of claim 1 are provided according to the invention. In particular, to solve the aforementioned problem in a cartridge adapter of the type described above, it is proposed that outside the A support area is formed on the contact area on the base body side to support a contact force applied to the cartridge side. For example, the support area can be positioned laterally, particularly in relation to the insertion direction of the adapter part and/or the cartridge. This allows for easy access. The support area can be designed, for example, as a projection, in particular a support ring, support collar, or at least a support mandrel. This allows for the simple application of a clamping force to a valve component. The basic body can, for example, have three hose connections, in particular a cold water hose connection, a hot water hose connection and a mixed water hose connection. The main body can, for example, be formed within the main pipe of a sanitary fitting and project, at least partially, into a cartridge chamber of the sanitary fitting. Furthermore, the adapter part is formed within the cartridge chamber and can interact with the section of the main body that projects into the cartridge chamber. Once the base body and the adapter part are positioned correctly within the sanitary fitting, a cartridge can be screwed into the cartridge chamber of the sanitary fitting, which exerts the contact force on the cartridge side of the adapter part. To advantageously prevent the contact force applied by the cartridge to the cartridge side of the adapter part from directly affecting the When the base body is transferred, the support area is formed outside the contact area between the base body side of the adapter part and the base body. The support area is preferably formed by the sanitary fitting itself, in particular by a section within the cartridge chamber of the sanitary fitting. A further advantage is that this allows for higher fatigue strength of the base body, as it is not directly stressed in the contact area with the adapter part. Furthermore, higher fatigue strength of the adapter part can also be ensured, since the contact force applied by the screwed-on cartridge does not cause wear on any contact surface of the adapter part that is in contact with a contact surface of the base body in the contact area. For example, the material of the adapter part can be reinforced in the support area. Alternatively or additionally, the features of claim 2 are provided according to the invention to solve the afor
