The invention relates to a high performance vibration damper (1) with a dual acting piston (23) movable in a sealed sliding manner in a tube (36). The piston (23) acts upon a fluid in the working chambers (A, B) by means of forced fluid circulation and displaces said fluid for damping a shock by means of a nozzle device (38) in such a way that the vibrational energy is converted into heat. According to the invention, the fluid thus heated is fed to a cooling device integrated into the high performance vibration damper (1). Said cooling device is configured as at least two chambers (C, E) located between the vibration damper housing (32) and the tube (36). The at least two chambers (C, E) interact with a suction channel provided for the working chambers (A, B) by means of at least one throttling device. The high performance vibration damper (1) thereby reliably prevents penetration of foamed oil into a working chamber (A, B) thus effectively preventing loss of functionality as a result of the low viscosity of the oil foam. The high performance vibration damper (1) is also characterized by a very compact and simple construction. |
