PISTON ASSEMBLY Russian patent published in 2020 - IPC F16F7/09 F16F9/06 F16F9/32 F16F9/36 

FIELD: machine building.

SUBSTANCE: invention relates to piston assembly 1 comprising piston sleeve 2 having longitudinal axis 3, piston rod 11 displaceable, in particular, along said longitudinal axis 3, and guiding device—damper 10 for guiding and damping piston rod 11 in piston assembly 1; 1a; 1b, comprising guide element 16 and at least one damping element 17. Damping element 17 is made enclosing piston rod 11 and comprises damping ring or at least one damping plate 26. Shock-absorbing ring or damping plates 26 are made from resilient material. Guide element 16 and damping element 17 are located in guiding device—damper 10 in undisplaceable manner. Guide element 16 comprises two half-shells 22, piston rod 11 is installed so that its free end 12 (first end) is located outside of piston sleeve 2, and its opposite end 13 (second end) is located inside piston sleeve 2. At second end 13 of piston rod 11 piston 14 is fixed, which serves as a means of preventing it from inadvertent pulling.

EFFECT: creation of a piston assembly with improved technical characteristics, in particular, such a piston assembly, which can be implemented in a simple and reliable manner.
