Abstract

A fluid housing of a fluid treatment system of a fluid system has a housing part of plastic material that is provided with a receiving chamber for accommodating a fluid treatment component; an installation opening, closable by a closure housing part, for installing the fluid treatment component in the receiving chamber; and a housing connecting section to connect the housing part to the closure housing part. A housing fastening section is provided with which the fluid housing can be fastened to a holding component of the fluid system. An insert is at least partially introduced into the plastic material of the housing part. The insert is provided with a reinforcement region extending with sections thereof in the housing connecting section and is further provided with fastening region extending with sections thereof in the housing fastening section. A fluid treatment system with such a fluid housing is provided.

First claim

What is claimed is:

1. A fluid treatment system of a fluid system comprising
at least one fluid housing, wherein the at least one fluid housing comprises:
at least one housing part of plastic material,
wherein the at least one housing part comprises:
at least one receiving chamber configured to accommodate at least one fluid treatment component for treating a fluid;
at least one installation opening, closable by a closure housing part, enabling installation of the at least one fluid treatment component in the at least one receiving chamber;

at least one housing fastening section forming a connecting flange protruding radially outwardly from an outer side of the at least one housing part and configured to fasten the fluid housing to a holding component of the fluid system;
at least one housing connecting section surrounding the installation opening and configured to connect the at least one housing part to the closure housing part;
at least one insert comprising metal and/or a composite material, the at least one insert at least partially embedded into the plastic material of the at least one housing connecting section of the at least one housing part, wherein the at least one insert comprises:
at least one annular reinforcement region of the at least one insert is embedded into the plastic material of the at least one housing connecting section such the plastic material is arranged on both radially outer and radially inner sides of the annular reinforcement region of the at least one insert; and
wherein the at least one insert comprises at least one fastening leg connected at a first end to the at least one annular reinforcement region of the at least one insert, the at least one fastening leg embedded, at least in sections, into plastic material of the connecting flange of the at least one housing fastening section.

2. A fluid housing of a fluid treatment system of a fluid system, the fluid housing comprising:
at least one housing part of plastic material, wherein the at least one housing part comprises:
at least one receiving chamber arranged in an interior of the at least one housing part and configured to accommodate at least one fluid treatment component for treating a fluid;
at least one installation opening, closable by a closure housing part, enabling installation of the at least one fluid treatment component in the at least one receiving chamber; and
wherein the at least one housing part has at least one housing connecting section surrounding the installation opening of the at least one housing part and configured to connect the at least one housing part to the closure housing part;

at least one housing fastening section forming a connecting flange protruding radially outwardly from an outer side of the at least one housing part and configured to fasten the fluid housing to a holding component of the fluid system;
at least one insert comprising metal and/or a composite material, the at least one insert at least partially embedded into the plastic material of the at least one housing connecting section of the at least one housing part, wherein the at least one insert comprises:
at least one annular reinforcement region of the at least one insert is embedded into the plastic material of the at least one housing connecting section such the plastic material is arranged on both radially outer and radially inner sides of the annular reinforcement region of the at least one insert; and
wherein the at least one insert comprises at least one fastening leg connected at a first end to the at least one annular reinforcement region of the at least one insert, the at least one fastening leg embedded, at least in sections, into plastic material of the connecting flange of the at least one housing fastening section.

3. The fluid housing according to claim 2 , wherein
the plastic material is at least partially injection molded around the at least one insert.

4. The fluid housing according to claim 2 , wherein
the at least one insert exhibits a higher mechanical strength than the plastic material of the at least one housing part.

5. The fluid housing according to claim 2 , wherein
the at least one insert is arranged such that the at least one insert has no direct contact with a fluid-conducting region of the fluid housing.

6. The fluid housing according to claim 5 , wherein
the at least one insert comprises a surface area of maximally 50% that is in direct contact with an environment surrounding an exterior of the fluid housing.

7. The fluid housing according to claim 2 , wherein
the at least one insert comprises at least one support section configured to positionally fix the at least one insert at least during embedding in the plastic material by injection molding the plastic material of the at least one housing part about the at least one insert.

8. The fluid housing according to claim 7 , wherein
the at least one support section is at least partially not covered by the plastic material of the at least one housing part during injection molding.

9. The fluid housing according to claim 7 , wherein
the at least one support section comprises at least one support surface.

10. The fluid housing according to claim 2 , wherein
the at least one fastening leg is integrated into the at least one insert, the at least one fastening leg extending outwardly away from the at least one housing part.

11. The fluid housing according to claim 10 , wherein
the at least one fastening leg is formed as one piece together with the at least one insert or is integrally formed on the at least one insert.

12. The fluid housing according to claim 11 , wherein
the at least one fastening leg is at least two fastening legs and
wherein the at least one insert connects the at least two fastening legs with each other.

13. The fluid housing according to claim 2 , wherein
the at least one insert comprises at least one support section configured to support at least one function component of the fluid treatment system.

14. The fluid housing according to claim 13 , wherein
the at least one function component is an inlet socket or an outlet socket.

15. The fluid housing according to claim 2 , wherein
the housing connecting section of the fluid housing comprises a radially inner thread arranged on an radially inner surface of the fluid housing adjacent to the installation opening, the radially inner thread configured to connect fluid housing to the closure housing part.

16. The fluid housing according to claim 2 , wherein
the metal of the at least one insert is selected from the group consisting of die cast metal and sheet metal and wherein the composite material is fiber composite plastic material.

17. The fluid housing according to claim 2 , wherein
at least the housing connecting section comprises plastic material selected from the group consisting of a fiber-reinforced polymer material, a particle-reinforced polymer material; and a fiber-reinforced and particle-reinforced polymer material.

18. The fluid housing according to claim 2 , wherein
the at least one fastening leg has a first end connected to the annular reinforcement region of the at least one insert;
wherein the at least one fastening leg has an opposite free end arranged outwardly away from the annular reinforcement region of the at least one insert;
wherein the at least one fasting leg includes at least one hollow fixation sleeve.
