Abstract

A hydraulic system, especially for motor vehicles includes a master cylinder, a slave cylinder and a pressure medium line connected thereto. The invention provides a hydraulic system which is simple or economical to produce by virtue of the fact that the hydraulic system includes at least one hydraulic plug-type connection with a plug connector and a socket contact and the plug connector includes an abutment and a sealing element which are made of different materials and which are connected together in a material fit.

Claims (12)

1. A hydraulic system comprising:

a master cylinder;

a slave cylinder;

a pressure-medium line connecting the master cylinder to the slave cylinder; and

at least one hydraulic plug-in connection having a plug connector and a plug socket, the plug connector including an abutment made of a first material and a sealing element made of a second material, the abutment integrally joined with the sealing element.

2. The hydraulic system as recited in claim 1 , wherein the hydraulic system is part of a motor vehicle.

3. The hydraulic system as recited in claim 1 , wherein the abutment and the sealing element are integrally joined to one another in a form-locking manner.

4. The hydraulic system as recited in claim 1 , wherein the abutment includes at least one of an injection moldable plastic, a thermoplastic elastomer, a liquid silicon rubber, and a general purpose elastomer.

5. The hydraulic system as recited in claim 1 , wherein the plug connector includes one of an external bead and an inner bead integrally molded on the sealing element.

6. The hydraulic system as recited in claim 1 , wherein the plug connector includes an annular groove and further comprising a clamping spring engaged in the annular groove, wherein the plug connector and the plug socket are connectable.

7. The hydraulic system as recited in claim 6 , wherein the plug connector and the plug socket are connectable in a positive locking manner.

8. The hydraulic system as recited in claim 1 , wherein the first material has a first color and the second material has a second color.
