Definitions
- a valve spring pushes the ball axially with a defined mechanical biasing force against the open end of the bore in the piston head, wherein the valve spring between the ball and a cup-shaped cap is supported.
- a radially outwardly directed flange of the pot-shaped cap bears with a defined force on a lower-side axial recess of the working piston, wherein a compression spring for generating the necessary pressure force between the flange of the cap and a bottom surface of a cylinder space of the housing of the support member is supported.
- the interior of the sleeve 44, an axially short portion of the radially inner space of the pressure member 22 and the radially inner space of the working portion 20 of the piston 24 form a reservoir 54 for receiving hydraulic fluid.
- the reservoir 54 is hydraulically separated from a Anberichtraum 56, which is formed between the radial outer side of the sleeve 44 and an axial portion 62 of the inner surface 60 of the pressure member 22 of the piston 24.
- the locking ring 86 is arranged in the second hydraulic path 72 and designed so that it can be flowed around by the hydraulic fluid largely without resistance.
- the locking ring 86 may be designed for example as a spring ring or snap ring.
