SHAFT CONNECTING STRUCTURE AND HYDRAULIC(PNEUMATIC) DEVICE Russian patent published in 2020 - IPC F16D1/06 F15B15/14 

FIELD: machine building.

SUBSTANCE: invention relates to hydraulic(pneumatic) device, and more specifically to connection structure of shaft for mutual connection of element in form of shaft and conjugated element. Connecting structure (45A) of shaft includes limiter (48) mounted with possibility of relative turn on piston rod (22) and equipped with multiple ledges (49) of engagement and multiple slotted grooves (50). Plurality of engagement ledges (49) are inserted into slit grooves (50). Plurality of slit grooves (50) includes a plurality of inlet grooves (56) and a plurality of inclined engagement grooves (60) extending in the inclination direction relative to the circumferential direction. Piston rod (22) and piston element (20) are connected to each other via restrictor (48) so that they cannot move relative to each other in axial direction.

EFFECT: simplified assembly.
