In the damper of the invention, consisting of a tubular body (1) and a coaxial piston rod (13) slidably disposed inside the said body (1), a graduation (7) has been formed. In addition to this graduation (7) which causes an enlargement of the body diameter, a second graduation (17) is provided at the lower end of the pipe. Two friction elements (8, 32) are placed between these graduations (7, 17) with defined internals between them. Two oiling rings (segments) (9, 10), placed between the said friction elements (8, 32) provide the reduction of the friction heat generated during the operation of the damper. The generated heat, furthermore, is discharged through two rectangular ventilation openings (30, 31) opened on the tubular body, thus the cooling of the piston rod (13) is facilitated. The oiling rings (9, 10) serve as the oil reservoirs by forming the necessary oil reserve cell (11) between the upper (8) and lower friction elements (32) while at the same time they prevent the friction elements (8, 32) to move towards each other, thus keeping the distance between the said elements, unchanged. |
