Abstract

The invention relates to a brake fluid container for a master cylinder in a hydraulic brake system. A safety valve is provided to ensure that the neck of the brake fluid container closes when the brake fluid container is detached from the master cylinder, for example in case of an accident. The safety valve is disposed in a cartridge which can be inserted from outside in a tightly sealing manner into the neck of the container.

First claim

The invention claimed is:

1. A brake fluid container for a master cylinder of a hydraulic brake system comprising:
a container base;
a neck protruding relative to an outside of the container base for insertion into a socket of the master cylinder;
a safety valve mounted in a cartridge which is inserted into the neck; and
a valve closure body of the safety valve which interacts with the socket so that the safety valve is opened when the neck is introduced into the socket, and is closed when the neck is located outside of the socket.

2. The brake fluid container of claim 1 , wherein the cartridge further comrises a sleeve on an outer lateral surface with an retaining element for holding the sleeve in the neck in a pressure-tight sealing manner.

3. The brake fluid container of claim 2 , wherein the outer lateral surface of the sleeve is provided with a circumferential bead, which is pressed into the inner lateral surface of the neck.

4. The brake fluid container of claim 1 , further comprising an inwardly directed circumferential collar at the end of the safetly valve sleeve facing the container, wherein the collar end surface is directed inwards into the sleeve and serves as a stop face for a valve spring and whose outwardly directed end surface serves as a valve seat face.

5. The brake fluid container of claim 4 , wherein the outwardly directed end surface is flat and runs perpendicular to the axis of the sleeve.

6. The brake fluid container of claim 4 , wherein the outwardly directed end surface has a funnel-shaped configuration and expands conically outwards.

7. The brake fluid container of claim 6 , wherein the valve closure body has a head which is located outside of the sleeve in front of the valve seat face, and has a sealing element located on its outer edge.

8. The brake fluid container of claim 7 , wherein the head sits on a shaft through which the sleeve is guided and whose lower end ends in a tappet.

9. The brake fluid container of claim 8 , wherein the shaft has in its central region a radial expansion whose end surface directed inwards into the sleeve serves as a counter stop face for the valve spring.

10. The brake fluid container of claim 9 , wherein the expansion is provided on an outer edge by recesses.
