Master cylinder assembly in brake system and piston stop

摘要

The present invention relates to a master cylinder assembly in a brake system and a piston stop. The master cylinder assembly comprises one or more piston assemblies. At least one of the piston assemblies comprises a piston (1), a piston stop (2) and a spring (3), wherein the piston stop (2) snaps into the piston (1), and the spring is retained between the piston (1) and the piston stop (2) and placed outside the piston stop (2). According to the present invention, on a circumferential wall of the piston stop (2) are provided deep slots (4) extending axially and running through the thickness of the circumferential wall, and these deep slots open towards one side of the piston stop where it snaps into the piston (1).

1. A master cylinder assembly in a brake system, comprising:
one or more piston assemblies, at least one of the piston assemblies comprising a piston (1), a piston stop (2) and a spring (3), wherein the piston stop (2) snaps into the piston (1), and the spring is retained between the piston (1) and the piston stop (2) and placed outside the piston stop (2), wherein a circumferential wall of the piston stop (2) is provided with deep slots (4) extending axially and running through the thickness of the circumferential wall, and the deep slots open towards one side of the piston stop (2) where the piston stop snaps into the piston (1), an “R”-shaped lead (8) provided at an end of the piston stop (2) where the piston stop snaps into the piston (1), and reinforcing ribs (12) axially provided on a circumferential inner wall of the piston stop (2) and disposed closely adjacent to the “R”-shaped lead (8) of the piston stop (2).
