TELESCOPIC HYDROPNEUMATIC SHOCK ABSORBER Russian patent published in 2022 - IPC F16F9/88 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering. The shock absorber contains a working cylinder filled with liquid and gas. A floating piston, elastic membrane or flexible bladder separates liquid and gas. The working cylinder consists of two telescopically connected glasses with oppositely directed open ends. The glasses fit snugly with side walls with the possibility of axial movement relative to each other. On the inner surface of the bottom of the outer sleeve, a fixing rod is fixed on its axis, passing through the axial opening of the hydraulic throttle, fixed in the open end of the inner sleeve. The diameter of the expanded head of the fixing rod is greater than the diameter of the axial hole of the hydraulic throttle.

EFFECT: increase in strength is achieved while simplifying the design, reducing weight and increasing reliability.
