In a master/slave cylinder system for clutches or brakes, primary seals have bevels which interact with similar bevels of formations on housings of the respective cylinders. Along with the lowest possible friction in the region of the sealing lips, this permits carrying out uncomplicated pressure/negative-pressure filling in the case of the master cylinder. The primary seals slide by the wedge of effects in the direction of the pressure on the bevels of the annular formations and reduce the annular bearing face of the sealing lip in a frictionally optimized manner.

Primary seals for master-slave cylinder systems

In a cylinder for a hydraulic system, a seal has a sealing bead clamped between a housing of the cylinder and a supporting part which holds the sealing bead in a deformed state by pretensioning. The seal is reliably held in its intended position by the supporting part and, therefore, pressure fluctuations in the pressure space do not cause a relative movement of the seal and wear of the sealing bead.
