Compressible shock absorber (100), characterized in that it comprises at least one couple of shock absorbing elements (110) co-axial and telescopic reciprocally sliding along a longitudinal sliding axis(X); said shock absorbing elements (110) co-axial comprise a cavity (115) and comprise therein a compressible air volume during their axial sliding reciprocal between a first position of maximum axial extension and a second position of lower axial extension; said at least one couple of shock absorbing elements (110) comprises air extraction means (140) susceptible of allowing an extraction of the air from said internal volume progressive with the reduction of the axial extension following the impact of a vehicle against said shock absorber. |
