摘要:
A tandem-type pneumatic brake booster, in particular for hydraulic vehicle brake systems, having a housing comprising a first and a second housing half shell, the interior of which is divided with the aid of a partition into a front and a rear booster chamber, wherein the partition has a centrally arranged, circular cavity, through which a control housing or a cylindrical control housing extension extends, and the partition rests sealingly against the control housing or the control housing extension by a sealing element, having a first and a second movable wall, which respectively subdivide the front and the rear booster chamber into a first low-pressure chamber and a first working chamber and into a second low-pressure chamber and a second working chamber, having at least one connecting conduit between the first working chamber and the second working chamber in order to equalize the pressure between said two working chambers.

摘要:
A cylinder, in particular for motor vehicle hydraulic brake systems, i includes at least one plunger piston (3) displaceable in a housing (2), at least one circular sealing collar (5) provided in an annular groove (4) of the housing (2) and having a dynamically applied inside sealing lip (6) which abuts with a first sealing surface (8) on the plunger piston (3), and a statically applied outside sealing lip (7) which abuts with a second sealing surface (9) on a bottom (10 of the annular groove (4), as well as a collar back (17). The collar back (17) has an uneven design and includes at least one circumferential sealing surface (18; 24).
